I am using an E4443A Spectrum Analyser and interfacing with it via SCPI commands using MatLab. I am trying to get a trace from the instrument similarly to what is returned by the 'trace:data? trace1' SCPI command, but I would like that trace to contain data reported by the 'Marker Noise' function. My current process is as follows: Turn on… Show more
I am using a switch in my test setup with some limiters on ports 1 & 2 of the analyzer. The limiters do not always clamp in time, and in this case port 1 was blown out on the analyzer (verified by turning correction off and connecting a load to the port and comparing against known data). My question is whether I can use another set of ports,… Show more
Hello, If Ports 1, 3 and 4 receivers are good then you should OK to use any combination of these as your 2-ports. The E5071C as a 4-port unit has eight receivers: References 1 - 2 - 3 - 4 (by port number) and Measurement receivers A - B - C - D (for ports 1 - 2 - 3 - 4 respectively). If you save Touchstone files then the numeric…

Can I create a LTE Systemvue project with only one UE, resource allocation type 1. The result CRC pass in VSA decode
Hi Specialist, I come from Vinsmart Company. I'm trying to use Systemvue to create the Reference Testvector for my RRH in LTE Project. So I create a project having only one UE, resource allocation type 1. But my result alway CRC Fail in almost subframe (as my picture). As I see, the pdcch data from Systemvue always not full the Symbol for… Show more
Hello Keysight team, Please help to retrieve the option 049 license key of E4403B s/n : US 39150120. The display screen is only monochrome. Thanks
I installed an option 101 card in an HP 8595E with option 151/163 and I get a conflict error when I want to use the Analog+ Display. Is there a way to use both card in the same unit without conflict ??? Is there a way to disable the fast ADC of the 151 OPT ???? There is a DIP switch on the 151 card but I don't know what it is used for ? Thanks… Show more
I am doing automation of Filter rmeasurements using Python code. I even got the S parameter values But I am unable to place a marker at a specific position. Do you guys know any command for that ? please do share with me.Thank you in advance. I am using GPIB to connect PC with hardware.
Hi, Good day. I had been using a Benchlink data logger 3 connected to a PC and it was used with a thermocouple for temperature reading. Recently when I tried to run it, the data logger response was very slow and end up with a error message pop up "ASRL1::INSTR : Operation terminated due to a timeout" I had try to reboot the PC and change… Show more
Hi, I tested my 34970A with DATAlogger 3 at 9600bps without problem. If I used this configuration with RS232 straight cable instead off a null modem cable (cross over), I have the error message "ASRL1::INSTR : Operation terminated due to a timeout". Check your rs232 cable, you need null-modem (cross-over) cable. Yves

Hi Keysight community, May I ask if it is possible to perform PLTS gating on a measured TDR plot TDD11 at the SMA launch region and observe SDD21 for the rest of the interconnect along the thru path? I read up some application material but many only describe using gating approach to observe just the reflections. Any insight will be much… Show more
HP 85047A contains HP 5086-7489 test port coupler which grossly fails simple directivity test (terminate with known-good APC-7 50 ohm load, and almost all source drive signal appears on the coupled port save for a notch/dip at mid-span. As the history of the test set is not known, abuse is suspected. Visual inspection inside the RF coupler… Show more

Hi, I recently try to do jitter measurement on DCA-X module 86108 for a 53G PAM4 signal. I have a deembedding function to remove a S4P file, and followed by a CTLE transfer function that applies 4dB peaking. In order to use those, I had pattern locked to PRBS13. Under Eye mode, I see that the eye is pretty open with 60+ mV eye height and… Show more
