Dear Sir,

We have an E3314A Programmable function generator of the Agilent and we need to execute the following test case using it.

Test case Details:

We need to generate a Trigger pulse with a time interval between two pulses is around 200ms and for 1000 times repetition only not continues using API or configuration settings.

Queries:

Can we configure the settings of this function generator to generate the trigger pulse for fixed repetition?
Do we require to enable any options in this E3314A to generate the trigger pulse of 200ms time interval for 1000 times?
We need to perform the same thing in E3314A as the trigger unit as shown in the attached image1.

Kindly guide me regarding this further.

Does the trigger go to anything besides trigger the Vector signal generator?
Would a marker output from the Vector signal generator work instead.
Use Vector signal generator to create modulation signal and also provide a marker output every 200 ms.
Use Arb sequencer to get exactly 1000 repetitions.
Use Arb Single trigger mode.

What are you really trying to do?

  Answer:
  Actually I need to measure the conductive sensitivity of one of my devices which supports both 2GFSK and OQPSK modulation using a vector signal generator.
  We have an inhouse E4433B ESD-G series signal generator which will generate 2GFSK and OQPSK modulated signal with below specification for the sensitivity test using external trigger in the signal from the E3314A Programmable function generator for the synchronization purpose.
  
  2GFSK Modulation with the following feature:
  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
  QQPSK Modulation with the following feature:
  Data rate:250Kbps
  Packet length:20byte(7 bytes payload)
  The external trigger in the clock from E3314A for the synchronization purpose:
  Time interval:2ms
  Every rising edge of the clock the SG need to generate a modulated signal with 1000 packets
  
  so the role of the E3314A in this test is to generate a trigger signal for the vector signal generator for the 1000 repetitions.
  
  Can we generate 2GFSK and OQPSK modulated signals in E4433B for 1000 repetitions without an external trigger signal using an internal marker function?
  
  In ARB mode How can we generate a waveform of 2GFSK and OQPSK modulated signals for 1000 repetitions?
  
  I request you to provide more details on it.

    Hi, it's possible to use EXT TRIGGER to send test pattern, see your other question "Query for E4433B ESG-D Series signal generator regarding 2GFSK.OQPSK Signal generation" message, I put sequence to activated this function with test result (2GFSK 64 bytes 35kHz 100kbps).
    
    EXTERNAL TRIG with UN8

Hi, just about your hp 3314A (not E3314A), it's possible to generate 1000 pulse based on only one TRIG signal (from datasheet hp3314A):

Dear Sir,
Many thanks for the valuable guidance and support.
It will be good if you provide more details on how can I generate a fixed 1000 trigger signal(Time interval: 2ms) using HP 3314A?
What configurations and connections are needed to make to generate 1000 trigger signals(Time interval: 2ms)?

  Hi,
  
  I guess you mean 1000 pulses based on a single TRIG signal. Select SQUARE waveform, adjust period to 2 ms, adjust symetry (duty cycle) if needed, adjust the number of cycles, and active external trigger.

Dear Sir,
Many thanks for the valuable guidance and support.
Let me clear my requirements regarding the use of HP 3314A.

With reference to above block-diagram,
I need to utilize the HP 3314A as an external trigger unit which provides 1000 trigger signals to my E4433B trigger input.
After getting the trigger signal, E4433B generate corresponding 1000 Packets of OQPSK or 2GFSK signals as per the rising or falling edge of the trigger signal.

What connections I need to make to perform the above test.
