GPIB Control / Data Software for 8720A VNA?


 

Hello again Group -
I have an 8720C and would like to be able to extract s2p files.
I do have a PC with GPIB, and also I have a plotter emulator which works great.
But I need a way to extract the data files.
Either free or up to maybe $1k - any suggestions?

Thanks
Dan


 

It's pretty straight forward.


I take the four real/imaginary S-parameter data pairs, using the Smith plot data retrieved by HPIB and write the data to a flat file.
See?

You¡¯ll probably want to use VNA.EXE from .? Strongly recommend a genuine National Instruments adapter for that application.
