Dear Sir,

We need to generate 2GFSK and OQPSK Modulated signal with below configuration on the E4433B signal generator by applying external trigger signals from the trigger unit.

2GFSK Modulation:

BT=0.5 of the Gaussian filter (BT: Filter Co-efficient)
Frequency deviation of 35 kHz
Data rate up to 100kbits/s NRZ
Packet length:64byte

OQPSK Modulation:

Data rate:250Kbps
Packet length:20byte(7 bytes payload)

The external trigger in the clock for the synchronization purpose:

Time interval:2ms
Every rising edge of the clock the SG need to generate a require modulated signal

In our E4433B Signal generator, we have purchased the following options.

Please find the below attachments for your easy reference.

Image 1: Measurement test setup diagram
Image 2: Enabled Option on my #E4433B signal generator

I have the following queries regarding above:

1. How to enable the external "Trigger In" option in E4433B for this test?

2. How can we configure the above Modulation settings in E4433B? Kindly provide me steps if possible.

3. Which options are needed to enable us to execute the above test for E4433B, if these options are not available?

I request you to guide me regarding this.

Hi Sagar,

I checked with the experts. This was their reply.

The ‘Custom’ mode found in the ‘Real Time I/Q Baseband’ (option UN8) menu would allow the user to select and configure 2GFSK as well as OQPSK modulation types per the requirements below. In addition the custom could provide user data files to meet their packet length requirements. Now for the big problem – The Real Time I/Q baseband mode does not support external trigger. I guess this could be done in the ARB mode (option UND) but the customer would need to create the waveforms.

Hope this helps.

Pete

Hi,

after reading the documentation and looking at the block diagram, my first answer would have been "that the 'Real Time I / Q Baseband' (option UN8)" does not support the TRIG EXT function, but this generator series is very versatile, and sometimes it's very difficult to detail all the possibilities, so I decided to test on my E4437B which has the same options as your E4433B generator, because TRIG menu is availaible with UN8 option.

After testing your 2GFSK sequence at 100kbps 64 bytes, I can confirm that the TRIG EXT function works with the UN8 option, as well as the TRIG BUS, TRIG button.

First, send SCPI command with Expert connection: MMEM:DATA "2GFSK_64bytes",#1520208. this will create a dummy pattern file which will be used to activate the TRIG menu.

Now, follow this sequence on your E4433A (front pannel)
PRESET
FREQ 10MHz (in my example)
LEVEL 0ddBm (in my example)
RF ON
MODE
Real Time I/Q Baseband
CUSTOM
CUSTOM ON
FILTER
SELECT
GAUSSIAN
FILTER Bbt 0.5
RETURN
SYMBOL RATE
100kbps
RETURN
MODULATION TYPE
SELECT
FSK
FREQ DEV 10kHz (in my example)
2-LVL FSK
RETURN
2/3 (page 2 of 3)
Pattern trigger (not available at this time)
return to page 1/3
DATA USER FILE
SELECT FILE
choose 2GFSK_64bytes
go to page 2/3
Pattern Repeat
SINGLE
Pattern Trigger
EXT
RETURN
RETURN
SAVE your setup

send pattern of 64bytes below with Connection Expert. (example of test pattern)
MEM:DATA:PRAM:LIST 85,20,21,20,21,20,21,20,21,21,21,21,21,21,21,21,20,20,20,20,20,20,20,20,21,21,21,21,20,20,20,20,21,21,21,21,21,21,21,21,20,20,20,20,20,20,20,20,21,21,21,21,20,20,20,20,21,21,21,21,21,21,21,21,20,20,20,20,20,20,20,20,21,21,21,21,20,20,20,20,21,21,21,21,21,21,21,21,20,20,20,20,20,20,20,20,21,21,21,21,20,20,20,20,21,21,21,21,21,21,21,21,20,20,20,20,20,20,20,20,21,21,21,21,20,20,20,20,21,21,21,21,21,21,21,21,20,20,20,20,20,20,20,20,21,21,21,21,20,20,20,20,21,21,21,21,21,21,21,21,20,20,20,20,20,20,20,20,21,21,21,21,20,20,20,20,21,21,21,21,21,21,21,21,20,20,20,20,20,20,20,20,21,21,21,21,20,20,20,20,21,21,21,21,21,21,21,21,20,20,20,20,20,20,20,20,21,21,21,21,20,20,20,20,21,21,21,21,21,21,21,21,20,20,20,20,20,20,20,20,21,21,21,21,20,20,20,20,21,21,21,21,21,21,21,21,20,20,20,20,20,20,20,20,21,21,21,21,20,20,20,20,21,21,21,21,21,21,21,21,20,20,20,20,20,20,20,20,21,21,21,21,20,20,20,20,21,21,21,21,21,21,21,21,20,20,20,20,20,20,20,20,21,21,21,21,20,20,20,20,21,21,21,21,21,21,21,21,20,20,20,20,20,20,20,20,21,21,21,21,20,20,20,20,21,21,21,21,21,21,21,21,20,20,20,20,20,20,20,20,21,21,21,21,20,20,20,20,21,21,21,21,21,21,21,21,20,20,20,20,20,20,20,20,21,21,21,21,20,20,20,20,21,21,21,21,21,21,21,21,20,20,20,20,20,20,20,20,21,21,21,21,20,20,20,20,21,21,21,21,21,21,21,21,20,20,20,20,20,20,20,20,21,21,21,21,20,20,20,20,21,21,21,21,21,21,21,21,20,20,20,20,20,20,20,20,21,21,21,21,20,20,20,20,21,21,21,21,21,21,21,21,20,20,20,20,20,20,20,20,21,21,21,21,20,20,20,20,21,21,21,21,21,21,21,21,20,20,20,20,20,20,20,20,21,21,21,21,20,20,20,20,208

After you send pattern with PRAM (volatile memory), you will have these results below.
It is possible to adjust rise and fall time of burst pulse (BURST SHAPE menu), for this test, I used default values).

When you turn off your generator and turn on, and recall your setup,you must toogle Pattern Repeat SINGLE to CONT and return to SINGLE, after load pattern with PRAM function, this action force BURST generation, after that, sequence is ready and wait for TRIGGER signal.

  Hi,
  
  Yes, with Expert Connection software version 2019 (latest version), you can connect to GPIB or RS-232 on your E4433B.
  
  With Expert Connection, just put the cursor on the interface where your E4433B generator is connected, in my case, NI-GPIB (GPIB0): right button of the mouse, I select "Rescan this Interface" ... after a few seconds, the generator type should appear. In my case, I have two generators E4437B and ESG-D3000B (E4432B).
  
  I also experimented with the RS-232 link, it is also functional and automatically, the COM1 port (ASRL1) is detected. With the RESCAN command, the generator is detected. However it displays "unknown" but, if one interrogates the device it answers. In the example, the command * IDN? has been sent.

      Hi,
      for your USB-RS232 interface, you need to add null-modem cable or adapter between interface and E4433B.
      I have similar USB-RS232 interface (COM232 Plus1), and it works with Connection Expert, but also works fine with a basic RS-232 software or NI-VISA (National Instrument) . You must set the configuration of the RS-232 with the same parameters that your E4433B. In Windows Device manager, verify if your USB Serial-Port is there. If your USB-RS232 interface appears in Connection Expert, click on +ADD button and choice "serial instrument on ASRL3 (COM3 in my case).
      
      .
      
      I have too a USB-GPIB interface but not from Prologix, but from National Instrument...it works fine. Unfortunately I will not be able to help you with your Prologix USB-GPIB interface.

        Hi, do you use a null-modem cable, because otherwise it will never work. If you use such a cable, check the pin-out with an ohmmeter to be certain. If pin 2 is connected to pin 3 at the other end of this cable, then it's a null-modem cable and everything should work fine.
        
        Here is a simple test that will check if your interface and the cables are correct. Connect your USB-RS232 interface to the PC, connect your null-modem cable too, but do not connect the last end of the cable to the E4433B:
        Do a test with the software Termite, sent a few characters, in my example "hello". you will only see your message in blue. Now put a jumper between pin 2 and 3 at the end of the cable and send another message: this time there will be a green answer if your interface and the cables are correct.

Dear Sir,

Thanks for the valuable guidance and continues support.

As per your suggestion, I have made RS232 null Modem cable and connected made set up as per your image and after that, I got the response from the E4433B is as below:

"*IDN?
<- Hewlett-Packard, ESG-D4000B, GB40051213, B.03.86"

Please find the below image for your easy reference.
After that, I have the following queries regarding this.
- What should I do next Sir?
- Can I perform your suggested SCPI commands using this or I need to use other commands?
one more point I am eagerly interested in the generation of 2GFSK signal using the TRIG EXT function.
I request you to help me with this.

  Correct Answer
  Hi, I tested all informations below on my E4437B with USB-rs232 interface.
  
           There are two methods to transmit pulsed modulation, either by a saved file (MMEM command: DATA) and external hardware to pulse the RF signal at the right time, or by a direct download in volatile memory (MEM: DATA command: PRAM), which normally requires no addition of external hardware.
           The saved file method does not allow control of the internal RF switch, and therefore requires the use of a, external generator's PULSE function or equivalent circuit.
           On the other hand, the method by the PRAM command contains the necessary commands for the control of the RF switch.
  
  So the simplest method is that of the PRAM command.
  To simplify the number of commands to send, we can save the setup in the generator that is recalled if necessary. The disadvantage, if the file is erased for any reason whatsoever, it must be recreated simply, about 1 to 3 minutes. If you prefer everything to be executed by SCPI command, simply replace the steps in the list with SCPI commands that you will find in the programming manual of your E4433B
  
  Preparation of the setup
  -> power on your E4433B
  -> After stabilization sent using your USB-rs232 interface the following SCPI command, this sequence is only used to access the TRIG menu when the time comes:
  -> MMEM: DATA '2GFSK', # 11A
  -> Then do the following sequence by pressing the appropriate buttons, this setup will be saved and can be recalled when the time comes. I put as 10MHz frequency and at 0dBm, you can change these settings now if you wish or wait later:
  
  ------------------------------------------------
  PRESET
  MODE
  RealTime IQ baseband
  CUSTOM
  DATA
  USER FILE
  2GFSK@BIT MOVE CURSOR ON THIS SELECTION
  SELECT FILE
  FILTER
  SELECT
  GAUSSIAN
  RETURN
  SYMBOL RATE
  100KBPS
  RETURN
  MODULATION TYPE
  SELECT
  FSK
  2-LVL FSK
  FREQ dev 35kHz
  RETURN
  CUSTOM ON
  2/3
  PATTERN SINGLE
  PATTERN TRIGGER
  EXT
  RETURN
  RETURN
  FREQUENCY 10 MHZ
  AMPLITUDE 0 DBM
  RF ON
  SAVE
  ENTER REGISTER NUMBER 0 TO 99, KEEP SEQUENCE = 0
  SAVE
  
  -> now the setup is saved.
  ------------------------------------------------------------------------------------------------------
  When you want use your setup after turn on your E4433B, send these 4 commands for recall setup and send 64bytes (512 bits) sequence. *RCL 0,1 it's the name of saved setup above
  
  *RST

  From this moment you have a pulsed 64bytes sequence, with external TRIG.
  When you turn off your E4433B and restart, you must redo these 4 SCPI commands to put your GFSK setup back on the road.
  You can change the value of 64bytes at any time sending your new sequence with the PRAM command.
  The explanation of the creation of this sequence follows below.
  ------------------------------------------------------------------------------------------------------
  HOW CREATE A SEQUENCE for PRAM command
  EXAMPLE FOR 2 BYTES to SEND: A5 B2
  A5 B2
  1010 0101 1011 0010

  how to create a sequence with the MMEM: DATA command (saved file)
  
  Take the example mentioned above of the 2GFSK file:
  MMEM: DATA '2GFSK', # 11A => 2GFSK is the name of the file to be saved, # 11A is the sequence content.
  
  Here the number of bytes is 1, it's A, because the number to be transmitted is actually h41 or 65 in decimal,
  the E4433B will therefore interpret the ASCII code of the character A as a byte of h41 value.
  
  After the position of the #, the first number (here = 1), indicates the number of digits that includes the next characters indicating how many bytes in all in the useful DATA.
  
  And the second digit 1 contains, 1 digit and indicates that there is only one byte.
  Here are two examples below.
  
  HOW CREATE FILE WITH DATA BYTES (MMEM: DATA 'filename', # 11A)
  #11A
  -> #
  -> 1 For the number of digits of the number of bytes that follows
  -> 1 number of bytes
  -> A It's the only byte in this sequence, WILL BE READ AS ASCII EQUIVALENT VALUE, IN THIS CASE "h41" OR "0100 0001"
  
  ANOTHER EXAMPLE
  #212ABCDEFGHIJKL
  -> 2 For the number of digits of the number of bytes that follows
  -> 12 number of bytes
  -> ABCDEFGHIJKL => h41 h42 h43 h44 h45 h46 h47 h48 h49 h50 h51 h52 => 0100 0001 0100 0010 0100 0011 .... 0101 0010

      Hi,
      You have mixed the MEM: DATA: PRAM: LIST and MMEM: DATA 'Filename' commands.
      MEM: DATA: PRAM: LIST gives you direct access to the memory and control of the RF switch (pulsed signal). There is no file name to give and the content goes into volatile memory. It is this command that you must use, if you want to have a pulsed signal. Look at the examples provided in the previous message.
      
      The other command MMEM: DATA 'filename', allows you to save your sequence in binary format, but you have no control over the RF (pulsed signal) switch.
      
      Command Expert does not support the E4433B, you have used E4428C or E4438C commands, so you can not use this software. Use Connection Expert instead.

      Hi,
      I made a basic RS-232 application to control your E4433B generator. Just specified the RS-232 COM port and connect. The text window to the left is the list of commands to execute, the next to its right are the commands that have been executed. The gray window completely to the right and the creation of the PRAM LIST file from the window at the bottom of the 64 bytes sent.
      If the signal is still present at the output of the generator (not pulsed), there is always the option that you must check and generate a new sequence. By putting a cable between the EVENT1 rear output connector and the input on the EXT2 front panel connector, it will be possible to pulse the signal. The pulse mode will then be automatically activated by generating the PRAM LIST.
      Don't forget to connect a trig signal source to the rear panel TRIGGER IN connector (0 to 5V).
      
      Regards
      Yves

Dear Sir,

Many thanks for the continued support and valuable guidance.

The new customize tool you have provided is good and easy to use regarding user perspective.

I have checked the behavior of the signal using your suggested tool.

It is continued in nature not flickering on or off.

Right now I don't have any external trigger source for triggering signal and I haven't provided that. It might be due to that it continues in nature.

If I want to use the internal trigger source of E4433B using the PRAM LIST command, then what should I do further?

Kindly guide me further as you do always.

  Hi,
  I added the TRIG BUS in the utility software, so you can adjust the time in ms, the trig will start by pressing the TRIG button. The blinking of the red LED indicates the sending of a TRIG signal. Minimum value is 50ms.
  Uninstall the previous version of this utility software and install the new one.
  
  When you start, choose right port number and RS-232 Connect
  Now, no setup to recall, you have a complete SCPI command set to send with Command to SEND button. There are 7 secondes delay for *RST command, and 200ms for each other commands to send, to be sure there are no "overrun RS-232" error.
  
  Now go to setup to do below (generator and scope).
  
  SETUP
  Do this setup with your generator and an oscilloscope. RF output of generator E4433B to channel 1 of oscilloscope.
  Do these connections: from EVENT1 connector REAR panel (red #16), to T BNC adaptor.
  From T BNC adaptor, one path to EXT 2 input FRONT panel (green #2) of the E4433B, and second path to channel 2 of the oscilloscope.
  Scope triggered by channel 2.
  
  FIRST TRY
  Push button Send PRAM, wait 2 sec
  Push button TRIG OFF, PC will send one *TRG command every 200ms
  
  => if you have result #1, every thing is OK. Nothing to do
  
  => if you have result #2, it's a FAIL: 2GFSK sequence is there, but RF always ON.
  In this case, stop TRIG sequence (red led stopped and always black on screen PRAM utility software),check the option pulse mode with EVENT1... and Send PRAM (pulse mode automatically turning ON). Push TRIG button (red led toggle). Now you will see on scope, the picture to the right.
  
  In my case, you have result #1 for my Agilent E4437B and result #2 for my hp E4432B. Same revision firmware for both generators but not the same revision code for UN8 option.
  
  Yves
  
  I've done a modification on last release, use V1.2. The problem was: after power ON of generator, the command "RAD:CUST:TRIG:SOUR BUS" didn't work for the first time. I reversed the order of execution of the last two orders. Now everything is working properly. If you use this list of commands in software, do not change the order since some commands are conditional on the previous one.

Dear Sir,
Many thanks and congratulations the commands and tools you have provided are working.

Again thanks for the continuous support and valuable guidance.

One thing I have observed that the generated trigger signal continues for every 200ms.

I required the triggering repetitions 1000 fixed.

It will be good if you can suggest to me equivalent commands for fixed 1000 repetitions.

I have a couple of more following queries regarding this.
- I need to generate a QPSK signal as well for the conductive sensitivity testing purpose using this and the following configurations are required with that modulation technique.
  OQPSK Modulation:
  Data rate:250Kbps
  Packet length:20byte(7 bytes payload)
- In my application, I need to change the time interval between 2 signals so it will be good if you can guide me further regarding this.
Again thanks for the continued support.it helps a lot.

  Hi, for time between pulse with TRIGGER BUS isn't no precise because is a TRIG BUS, there are time processing for PC, RS-232 and generator. You have result on picture below. Period corrected is 200.2msec (mean on 256 samples), min 171.6ms, max 226ms and standard deviation is 9.486ms. To have precision, you must use external generator with burst count 1000 cycles. It's possible to use internal generator low frequency internal to E4433B, but there are no flexibility. You must answer to some question below and after I will send you a new version of software and command list.
  
  You said "the commands and tools you have provided are working.", Have you used the option PULSE MODE with EVENT1..... It's important for me to know this information.
  
  Now for your OQPSK, what king of filter you need, gaussian BT 0.5 ?
  What is the value of time between pulse, 200ms for 2GFSK and for OQPSK ? it's a fixed value for both?
  
  For better time period stability, I will try to use internal low frequency generator to E4433B.
  If I use the internal low frequecy pulse generator, there are no pulse count, but by software I may count a period of 200 seconds (1000 pulse of 200ms), because there are processing between PC and E4433B, maybe the precision will be 1000±1 count, it is important to have exact count of 1000 ?
  
  While waiting for your answers, I will check the accuracy of pulse counting.
  If a use TRIG BUS, it's easy to have exactly 1000 pulses, but timing precision will be like the picture above.
  
  Yves
  
  ------------------------------------------------------------------------------------------------
  
  Finally it is possible to have a precise chronometry and to have control for an account of 1000 transmissions. I used the low frequency generator of the E443xB, and after several tests I noticed that the output LF OUTPUT offers a signal with a sufficiently stable delay after sending commands ON and OFF.
  
  I created 2 lists of commands, one for the GFSK the other for OQPSK. The GFSK tested at 200msec by TX, and the OQPSK at 25msec, thus maintaining the same TXon / TXoff ratio as the 2GFSK.
  
  I tested the signal OQPSK and 2GFSK on a N9010A and a 89441A and everything is correct.
  
  The accuracy of the vb.net TIMER function is still limited, the longer the interval will be, the more the 1000 count will be accurate for your application. Using a 53132A frequency counter in Totalize mode, I checked the software and the E443xB for an account of 1000 packets. After several hundred trials, the result has always been 1000, for OQPSK (25ms) and 2GFSK (200ms). Using a "thread" I could have had greater certainty (accuracy), but the PC would have been frozen during the test period, ie 200sec for the 2GFSK.
  I miss some information requested above, after which I will send you the modified software.

repetition:1000 fixed

The reason behind this is that I need to perform the RF conductive sensitivity test of my device with help of E4433B.

In conductive sensitivity measurement, I will provide 1000 packets either(2GFSK or OQPSK) modulated from the E4433B to DUT by reducing the amplitude of the signal lower using passive attenuator and cable.

At the receiver side, I will measure the same 1000 packets and according to received packets, I will calculate the Packet error rate in percentage(Received-transmitter).

The pass criteria for my test are:<1%PER.

      Hi,
      
      Here is the final version based on the information you provided me. I checked on a 89441A that the contents of the packets were error-free for the OQPSK as well as the 2GFSK. For the OQPSK test, a sequence containing only A0 values was used to easily check with differential encoding or not.
      
      The default sequence for 2GFSK is a PRBS 2 ^ 9-1 for 511 bits followed by a logical level 1 bit for a total of 512 bits or 64 bytes.The default sequence for the OQPSK is simply a combination of a sufficient number of runs on the demodulated signal constellation, in order to quickly evaluate if there is a problem.
      
      An important note: I used the low frequency generator of the E443xB to synchronize TX sending, but its output level is programmable, but not its offset, so I limited the level to ± 2.5V, the input to Pattern Trig connector can take from -4V to + 8V before damage. The trigger level is that of a TTL threshold, I checked and it was 1.4V, so with + 2.5V you are correct.
      
      To be able to generate 1000 packets, it was necessary to use a function TIMER in vb.net, as mentioned, but this function has a limited precision, but sufficient for your application according to the tests that I carried out. The value of this TIMER is equal to the requested period, here 200ms, +9/25 of this period.
      
      You can use the EVENT 1 connector to synchronize your measurement devices if necessary.
      
      Here are some results below, I wish you good luck in your project.

  The option UN8 do not support HALF SIN filter, to do that, you must create arbitrary waveform for UND option. This means that you need to do digital processing before sending it to the E4433D option UND. All the work on the OQPSK was useless, because of the bad information.

    Hi, it's a follow up from last message.
    
    About the 3 items:
    1 - The signal I is inverted at OUT I connector only, but not on RF signal. Verified with 2 differents instruments.
    3- Now I understand the mechanism of the markers and able to put the RF switch OFF to increase performance.
    2- With MARKER 2 feature, it's not necessary to turn off ALC. However, after activating the UND (OFF to ON) function, the RF level is within -5dB of the programmed value, it will adjust to less than 1dB after the first 7 pulses (regardless of the time between the paquest). After the first 7 pulses pass and as long as you do not do an OFF-ON cycle again, the level will always be nominal. We must redo an OFF-ON cycle, when we change the contents of packages, or when we go from FSK to OQPSK. I also noticed that if we leave the system without sending packets for a prolonged period, there may be a level error on the first impulse ... the error does not exceed 5dB for the first impulse. I make this remark in case it influences your test.
    
    This the last version of application software (V3.0 with half-sin pulse shaping filter for OQPSK).
    
    note: parameters variable: number of packets (was set to 1000), number of bytes (was 64bytes for 2GFSK and 20 bytes for OQPSK), time between transmissions.
    
    Have a good week-end

  Hi,
  I still had some free time, so I did the processing for a signal with half-sin pulse shaping filter. I have used the UND option you also have on your E4433B. I managed to keep the same hardware setup to generate the signal. Pulsed mode works well, but there are some things to keep in mind:
  
  1- the signal I is inverted, it may be some formatting E443xB because the sequence sent is really non-inverted ... but perhaps also a bad understanding of the UND option.
  
  2- It is necessary to deactivate the ALC and to make a manual adjustment of the power, however this is noted in the documentation of Keysight on this generator. I just have to check if everything is stable and compliant.
  
  3-It remains for me to understand the mechanism of the markers to be able to put the RF switch OFF, at this time without any active markers, the RF OFF is at -60dBc (on my generator), this is due to the offset I and Q. If that does not you cause no problem I can leave as well.

  Hi,
  I'm in the process of re-checking all the setups. I have a small correction to make on the software in relation to the number of bytes that we can transmit (just an error in declaring an incorrect variable).
  I was also able to use the UN8 option to do the OQPSK modulation with the halfsin pulse shaping filter. I will see which solution would be simpler and more efficient.
  In the meantime, a question, is it your OQPSK signal that you are looking to create is it actually a standard Zigbee signal 2450MHz, or simply a different application.
  And does your 2GFSK signal have to meet a particular standard?
  How will you demodulate your GFSK and OQPSK signals?

  Hi,
  
  I realize that there may be confusion with the TRIG signal, there are two possibilities based on my E4437B and E4432B generators. For the same setup with a same PRAM command, they behave differently despite having the same firmware version, whereas normally it should not. My Agilent E4437B create pulse output, while my HP E4432B does not, it create the sequence of bytes correctly, but the signal is not pulsed but continuous. I read on different forums this kind of behavior. Is it an internal failure or that the old versions of the UN8 option do not support this mode, however the PRAM command should allow this function. I have not yet found an explanation for this behavior, but we can work around the problem if you are ever in this case.
  
  The use of the PRAM command gives control for a pulsed signal, and also makes it possible to have a signal on the EVENT1 port if necessary. You can program markers (pulse for a trig on the oscilloscope for example).
  
  The question to answer for you: if you use the following setup, either, connect the LFout signal to the Pattern TRIG in connector and you have a pulsed signal as in image #1 (E4437B) you have nothing else to do. On the other hand, if the RF signal is not pulsed as in image # 2 (E4432B), then you will have to add a cable between the EVENT1 output and the connector on the EXT 2 input panel to allow using the PULSE mode. At that time, you only have to connect this additional cable and activate the pulse mode function with the software and send PRAM, you will have normally, same result as picture #3
  
  ========================================================================================
  About your questions on 3 remarks:
  For the 3 remarks I had made on the UND mode (OQPSK halfsin), you have nothing to do. I replied in a message following these 3 notes (see italic text below which is a copy of the answer)
  1-I noticed that the signal is reversed at the Iout connector. No impact on your project, it's a simple remark.
  2- I understood the mechanics of markers 1 and 2 which come with UND mode, and I used it to improve performance.
  3- for ALC mode, I studied the behavior, it is simply to warn you, but in my opinion this will have no impact, but if in doubt, ignore the first 10 pulses and look at the 1000 others to follow.
  
  "1 - The signal I is inverted at OUT I connector only, but not on RF signal. Verified with 2 differents instruments.
  3- Now I understand the mechanism of the markers and able to put the RF switch OFF to increase performance.
  2- With MARKER 2 feature, it's not necessary to turn off ALC. However, after activating the UND (OFF to ON) function, the RF level is within -5dB of the programmed value, it will adjust to less than 1dB after the first 7 pulses (regardless of the time between the paquest). After the first 7 pulses pass and as long as you do not do an OFF-ON cycle again, the level will always be nominal. We must redo an OFF-ON cycle, when we change the contents of packages, or when we go from FSK to OQPSK. I also noticed that if we leave the system without sending packets for a prolonged period, there may be a level error on the first impulse ... the error does not exceed 5dB for the first impulse. I make this remark in case it influences your test."
  ========================================================================================
  I was able to obtain a TRIALlicense for the VXA option of my N9010A, until January 16. I checked a Zigbee module at first to familiarize myself with this application. But if you tell me that your OQPSK halfsin pulse shaping signal is for a signal respecting the Zigbee standard, this means that you will have to create a compatible Zigbee FRAME before sending it via the UND option of your E4433B. If you copy the list of bytes to be sent to my software, then the signal should be recognized as a Zigbee signal. It is an experiment which I will try to make.
  
  Hence my question: the pulsed signal you want to test, is it a Zigbee signal, or simply an OQPSK halfsin pulse shaping signal which is not an industry standard.
  
  The same question also applies to the 2GFSK signal, is it linked to a known standard like Bluetooth or DECT for example. If so, your E4433B has these options.
  
  The PER that you make on your modules is a known and fixed or variable package like a PRBS sequence.
  These answers have an impact on the possible use of your E4433B generator and its different options.

  Hi,
  
  First, I would like to thank Keysight for granting me a 1 month VXA demo license for my N9010A, this allowed me to test the generation of a Zigbee signal using an E4437B and E4432B generator and try a config Zigbee on a 89441A.
  
  Unfortunately i'm busy on a project right now and i don't really have any more time to devote to generating the Zigbee signal on the E443xB generator. However I have successfully completed the experience of creating Zigbee on this type of generator, here is a very brief summary and a small PDF document showing the results using a Zigbee MC13202 transceiver as a reference receiver. I wanted to make more complex frames using the MRF24J40, but I ran out of time, the work had started but could not be finished. Here are the important points:
  
  - An E443xB type generator with the UN8 option can generate a Zigbee signal in the standards. I have used two types of commands successfully: BIT file and PARAM list.
  - An E443xB type generator with the UND option can generate a Zigbee signal in the standards. This approach gives the best EVM performance until proven otherwise (I haven't had time to optimize EVM performance with the UN8 option).
  - An 89441A can be configured to receive a Zigbee signal, and compared to an N9010A with VXA option, the EVM is slightly less efficient, but everything else works correctly.
  I used the documents you sent me to do this work to produce modulation DATA.

Dear Sir,
Once again many thanks for sharing your valuable guidance and experience with me.
How is the situation at your side due to COVID-19?
I hope all are going well with you.
I hope you are fine nowadays during quarantine.

In India, the sudden rise in COVID-19 cases in India over the past few weeks has forced the nation to a standstill. In the interest of national health and safety, the government has promptly announced a complete lock-down in India till 14th April 2020.
So I am working from home during the quarantine.

No problem, Sir, If you are busy on another project. I can understand.

I have checked the file which you have attached.
It helps me a lot.
It will be good if you can share with me the utility files so it helps me a lot to generate signals and validate its EVM using VSA.

  Hi,
  sorry, yes I read your message, but I have to finish a pressing technical document on a project. Yes I will send you this week the utility that I used, but also how to code the Zigbee signal if you don't know, it's relatively simple (when we have to find out how obviously), the most complicated was to understand how to program the RF generator.
  
  We too are touched by covid-19, like a good part of the planet, we are in containment and the shutdown of the majority of industries. I also work at home but I did it before because I am self-employed. In the meantime, I hope that on your side everything will be fine.

    Dear Sir,
    Many thanks for the valuable reply and support.
    
    It's good to hear that you are in a safe place.
    
    I have a few more details which I need to share regarding the 802.15.4 Zigbee frame structure format.
    
    ********************************************
    Regarding 2GFSK Signal FSK PHY frame structure,
    
    you will get the preamble, SHR, PHR and Payload details from the below document.
    
    Please find the attached document MAC AND PHY SUB-LAYER CLARIFICATIONS (Page No:21 to 24).
    
    I need to use a 127byte payload later instead of 64Byte for better results comparison using your utility the same as the Zigbee alliance.
    Do we have the support of the configuration of the payload in the utility?
    
    *******************************************
    Regarding OQPSK Signal PHY frame structure,
    
    I have found the following image for more reference.
    Same as in the future we need to use 64Byte Payload later to perform the Total Radiative Sensitivity test using the same configurations of VSG as per the JTM 3.3 Document.
    
    What should be the PHR value as per the above image for 64Byte length of payload?
    Do we need to convert the length of the frame from binary to decimal or binary to hex in the utility?
    
    Once I will get more details regarding the OQPSK I will share it with you, sir.

      Hi,
      
      The utility software does no Zigbee framing or CRC calculation. It is up to you to create your FRAME in hexadecimal mode and write it in the "Byte to Send" window. The utility will then make the necessary transformation so that the generator can transmit the signal to OQPSK or FSK required for the Zigbee.
      
      "Do we have the support of the configuration of the payload in the utility? " = no, utility is just to convert your packet of bytes to RF signal OQPSK or 2GFSK.

  Hi,
  this is the latest version of the utility software for your E4433B. Unfortunately, I used only GPIB and not rs-232 because I too often had "overrun errors". I tried to use handshaking without much success. But you have a GPIB Prologix interface, it should work well, enter the address of your E4433B in the window assigned for that.
  
  You have 2GFSK, and Zigbee halfsin OQPSK with UND option (best performance) or UN8 option (possibility to change some parameters like IQ mapping). Software tested on N9010A and 89441A (result in pdf document).

  Hi,
  Point 1: regarding the address of E4433B
  Press
  PRESET button
  UTILITY button
  softkey GPIB/RS-232
  You can see GPIB address on top softkey
  
  How can I get the address of E4433B using GPIB Prologix?
  In this example below, replace the number 23 by the number of your E4433B address.
  If you only have one GPIB interface connected to your computer, the number after GPIB remains 0.
  Press RETURN KEY, and if everything is OK, message similar to below will appear (Hewlett-Packard, E4433B, …). If not, message will be “E443xB not connected”.
  
  Point 2: Regarding Payload size
  Can I increase the size of the payload in the utility for OQPSK?
  Yes. Limit is the pattern RAM of your generator. I tested up to 1024 bytes for UN8 PRAM list and 256 bytes for UND option.
  
  If I need to configure own hex data byte information then how can I configure the data in the utility for both 2GFSK and OQPSK?
  Just write hexadecimal bytes to send in the windows.
  Utility software use Zigbee coding 32bits/4bits to send and halsin filter for OQPSK modulation (8 samples/bit for UND, and 20 samples/bit for UN8).
  
  I made an improvement for the bytes input window. But before sending you an improved version, I would like to retest the Zibgee module based on the MC13202 to see if everything is working properly, there I am busy now, probably not until next week.

Dear Sir,

I need your valuable guidance regarding the use of Utility which you have prepared as per the special requirement.

It will be good if you can provide me the procedure steps or document(Which describes the information regarding the what sequence I need to maintain using a utility to successfully run the test) which helps me while performing the 1000 packet test of 2GFSK and OQPSK using E4433B.

Another point is regarding the Receiver Section.
You have used MC13202 Zibgee transceivers as a receiver to receive 1000 Zigbee packets to get the PER data of the chip.
Please find the below image for more reference.

It will be good if you provide me more details regarding that
- Does your utility regarding the receive window section as shown in the above image support other chipset configurations or it is another utility especially you have prepared for Receiver?
- What should I do if I need to use other Zigbee transceivers as a receiver to receive 1000 Zigbee packets to get the PER data of the chip(Like JN5169 and OL2385 chipsets)?
- What hardware connection required at the receiver side? Can I use a term or other tool for receiver configurations and logs?
- What are the requirements required regarding receiver side configuration using the tool?

I request you to guide me further in this regard.
