Hello everyone, I am doing automation of Sparameters of filter using python coding and GPIB cable. I can able to change the frequency after calibration manually but I cannot do it using code. . I created a class named network analyzer ,in that I gave definitions, to call them I created an object (aaa).I am attaching the respective code below,… (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)

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)

Hi, We use a E5071C for tuning NMR probes here in our lab.  We use very few of the options available, mainly use for fault diagnosis on probes and tuning to a resonant frequency. We normally look at S11,S22 and S33 of the 4 available ports.   This last week an unusual display popped up on S11, it's a sinusoidal waveform across the whole… (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.

The on-line help  Rev A.13.70 (M980xA/P500xA)   Rev A.13.10 (P937xA)   Rev A.12.60.xx (M9485A/M937xA) -  2-Jul-2019 states that the M980xA doesn't support the multi-site function. Is this because the M980xA is new and the "firmware" hasn't been updated yet for the support or is there some other reason?  PXIe VNA Multisite Note: M980xA does not… (Show more)

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)

Hello.   I am trying to perform a 2-port calibration on a PNA N5225A (Application version A.09.40.06) at different temperatures.   The normal way would be by performing a full calibration at each temperature, but then I would have to connect the standards each time that I change the temperature. This is not an easy task the setup that I use. I… (Show more)

Is this (NA) mode the only mode we need to wait for it to warm up, right?  For how long? still 30 mins?

Hello   My configuration is N5247B-423 + N5292A + VDI mini module extender for WR6.5. The error message "-224 Illegal parameter value" pops up after I upgrade the firmware to version A.13.60.06 I can't fix it even I reboot or  preset PNA or even re-install firmware. This error messege shows only under millimeter-wave mode. It never occurs… (Show more)
