Re: 34401A issue
Thanks.? I get 4 errors: 612, 613, 618, 619 Three of these have to do with resistance, maybe I needed to short the input, but as resistance works (I just tried with a range of high precision

Re: HP8510C TRL Calibration
I see the 'switch terms' can be obtain using skrf.vi.vna.hp.HP8510C ( https://scikit-rf.readthedocs.io/en/latest/api/vi/generated/skrf.vi.vna.hp.HP8510C.html ) so it'll be interesting to see how that

Re: 34401A issue
Hello Peter, Try to run a Self Test and see if it passes it. Could be anything but older 34401A have relay faults. The OMRON relays can be found but not the COTO relay. Newer 34401A had a newer

34401A issue
I have an Agilent 34401A which I've used at my bench for many years. Today I went to measure a 12 volt battery and it just started clicking. I tried it on a power supply and auto ranging works fine

Re: Shipping overseas?
Maybe. Ship printed circuit boards to Germany, from the U.S., using a 'Priority Mail International Flat Rate' medium box. (or small, or large too) AFIK, you gotta use customs form 'PS Form 2976-A' On

Re: Shipping overseas?
Hi Gary, I had similar problems from Canary Islands to Canada. They told me Canada would not allow electronics so I send the stuff to Germany with a friend and he could send it to Canada with DHL

Re: HP8510C TRL Calibration
I note the HP8510C driver, so i should be able to use this to access the 'switch terms. Also i'm interested to see how fast it reads the s-parameters! Thank you for this, N

Re: HP8510C TRL Calibration
However, when i run from the PC and file data, the first line in the s2p file is: !HP8510C.07.14: Aug 26 ?1998, so that indicates a different software version. (well the monitor is CRT, so pretty

Re: HP8510C TRL Calibration
I've been looking at scikit-rf to do the TRL calibration and it mentions using the 'switch terms' to improve the calibration. I'm just wondering, how do i read the switch terms from the HP8510C, which

Re: Shipping overseas?
Hey, in the past, I used Stackry and was happy with their service. MyUS was also great when it came to handling and shipping but their small print can inflate your budget. This is 5 yr old

Re: HP8510C TRL Calibration
Hi Ed, i did manage to get the NI GPIB / USB to laptop interface working. In terms of running the 8510C from the laptop it seems to work quite well but only with uncalibrated data. From the Operation

Francesco, From the Keysight parts finder, the picture shows that part number has several discrete components on a circuit board. Three ICs, and numerous R and C. No commercial equivalent but might be
