Re: Measuring Phase with Agilent E5062A ENA
So I tried a quick test on my test cable and when put in the smith chart mode it functions in a similar manner to a Cartesian phase plot where the data is displayed from -180 degrees to +180 degrees,

Re: Readings from 436A power meter using 82357B USB-GPIB?
And if you're into Linux, there is a GPIB driver package available with bindings for python and perl. It's at https://linux-gpib.sourceforge.io/ and supports USB adapters as well as older

Staffan, Have a look at python https://pyvisa.readthedocs.io/en/stable/rvalues.html I am from the generation that used to use FORTRAN IV and punchcards but you have to move up with times at some

Re: Measuring Phase with Agilent E5062A ENA
Hi Dave. The machine does actually have quite a bit of capability and I find it vastly superior to the older HP VNA's I have had in the past.? The problem is it is so poorly documented or not

Re: Readings from 436A power meter using 82357B USB-GPIB?
Hello, I can control the instrument so I guess termination is correct, but reading isn't working. I'd really like to do the low level byte by byte communication, but anyone knows hos to do this with

Re: Measuring Phase with Agilent E5062A ENA
You could save the data as a Touchstone file the import it into the software used for the VNWA. https://www.sdr-kits.net/DG8SAQ-VNWA-software-documentation-user-guide and display as "c. phase" which

Re: Measuring Phase with Agilent E5062A ENA
Hi Alwyn, thanks for that suggestion. Yes I am pretty sure the 5062A has that capability. I will give it a try and see how it correlates with the expanded phase option I think will also do exactly

Re: A homemade diode power sensor for HP meters
Tobias Interesting project. I am surprised that you had trouble finding 848X schematics. They are in every service manual from the 1980's? ( and we of course have them available for modest purchase

Hi Guys, sorry for my late reply. Today I was able to make some further progress. Robert was right in his post (/g/HP-Agilent-Keysight-equipment/message/92641) - the autozero

Re: Readings from 436A power meter using 82357B USB-GPIB?
Many older instruments don't use the EOI line, but also "Must" have the correct command terminator byte (if one is specified) no more, no less.. It'll all be documented in the individual instruments

Hello, Thanks for the suggestion. I have tried this, but it doesn't seem to work. Any recommendations to how I should configure Interactive IO? I will use Visual Basic in Excel for later programming

In my connector search above, I didn't pay any attention to how the connector mounts onto the device.? For a new homebrew design, it probably doesn't matter.? But, if you are specifically trying to

Re: A homemade diode power sensor for HP meters
The 12-pin circular connector used on the power sensors is an Amphenol.? The old part number was 91-T-3638. Now, it's part of their "C 091 A/B/D" series circular connectors.? Several variations are

Re: Measuring Phase with Agilent E5062A ENA
Dear Gedas, There is a way round this you might find useful- reference line extension function; I used this on an 8753B to take out the delay in a long optical delay line. Essentially, you sweep

Have you tried displaying your results on a Smith chart? Check out Dr Joel Dunsmore’s book, “Microwave Component Measurements” for more than you ever wanted to know on the subject.

Re: A homemade diode power sensor for HP meters
Yeah, that would be bad, essentially counterfeit sensors made from shells of fried ones.? And they would sort of work, just nowhere near spec.

Re: Measuring Phase with Agilent E5062A ENA
Thanks for that. It does in fact say phase is measured +/- 180 degrees. Earlier I ran a quick test using the expanded phase format and I think it is in fact exactly what I want. Below is the same
