GPIB scripting software?

Ulf Kylenfall Member Profile All Messages By This Member #146981 Looking for suggestions regarding useable GPIB script routines that can be used for setting up a system with 897B/8971C and a Local oscillator system. It does take some time doing this step by step. ? No need for retrieving data but using a routine that initializes all parts would be nice. ? I saw a thread about Matlab routines but not having an account with Mathworks since I left the university and not wanting to try either 30 days trials or 20 hours "online" a month, I am looking for a lasting alternative. ? Cheers ? Ulf Kylenfall SM6GXV

Harke Smits All Messages By This Member #146983 开云体育 Hi Ulf, I have developed some Python routines that do just that: control the HP8970B/HP8971C/HP8673B. I can send them to you. They are basically testroutines, but set up the system correctly and wil allow to make measurements. It assumes the Keysight IO system works correct. Run from Windows command prompt. Let me know if interested.

Askild All Messages By This Member #146984 Hello Ulf, Python is another possibility. If you have not used python before, you should find a lot of info online.? Even ChatGPT has gotten fairly good at writing python code, so if you give it a good description you will have a good starting point. It will probably not be able to make it perfect, but a good starting point for beginners.

Ulf Kylenfall Member Profile All Messages By This Member #147083 ? I have submitted my e-mail address to Harke Smits. ? In a project some years ago, I used python routines written by others but never had the time to dive into this language. ? Looking forward to what I will receive. ? Cheers ? Ulf Kylenfall SM6GXV

Andrew Hakman All Messages By This Member #147097 Python + prologix adapter is about as simple, portable, and dependency free as it gets. Open the port with the python "serial" library, and send direct GPIB commands to it.

Mark Bielman All Messages By This Member #147101 开云体育 Agree. Very simple. I use it a lot. Word of warning: Older HP instruments (and probably others, pre SCPI I'd say) do NOT like the "auto-reply" and you should disable that.

Harke Smits All Messages By This Member #147106 开云体育 With free Python libraries like sci-kit, numpy and matplotlib you probably do not need Matlab (licensed) anymore. The Matlab clone Octave is for free. With the mentioned Python libraries it takes only a couple of lines of code to read a touchstone file and plot the 4 s-parameters on a Smith chart. There are examples to design an microwave lna based on these libraries (yes some more lines are needed). Nice stuff, I only scratched the surface so far.

Harke Smits All Messages By This Member #147107 开云体育 Do you have a simple example at hand? I used the Prologix adapter in the past with KE5FX toolbox but never with pyvisa. I prefer to use Python as I want more data processing options than available with the kit.

Dave_G0WBX All Messages By This Member #147108 Did anyone mention EZGPIB? Windows only, works with NI and Prologix (but not all clones though, without some effort.) It does work with NI USB-GPIB devices, running in a Windows VM guest on Linux.? The NI baggage, only needs installing in the Windows guest VM, not on the host. The scripting language is Pascal based, so easy to learn.? All the GPIB handling is done for you, so it's just the basic instrument programming you need to figure out. Free too.? Sadly it's author has passed, but his site lives on. A lot of other good info there too.? Including worked examples in the download for several popular instruments and tasks. Dave B.

John Miles All Messages By This Member #147121 开云体育 Somewhat OT, but: ChatGPT is quite good at turning English into Python, especially if you have a subscription that allows you to run their latest chain-of-thought model.?

It knows about scikit-rf, but you have to download and run the resulting Python program yourself (which is relatively trivial even in Windows these days). ? ? I didn’t ask it about retrieving GPIB data, and wouldn’t expect miracles if you ask it specifically about Prologix device access.?
