SCPI command examples for the most common tasks that can be adapted to any programming language.
These examples are available from github: https://github.com/Terrabits/vna-scpi-examples
The following documentation is taken from the included readme.md file.
This project contains several Rohde & Schwarz VNA programming examples to help you get started. The examples are in python, but they all use raw SCPI commands and can be translated with a little effort into any language. Each script is commented liberally to help in this regard.
The examples are divided into sections. SCPI command documentation is also included in the commands\ folders for each section. This documentation comes from the ZNB manual.
The examples are organized into the following sections, with a folder corresponding to each:
Query the VNA model, number of ports and frequency range to make sure that it suits your needs before you start measurement.
Programmatically control calibration with an autocal unit as part of your test automation.
Apply deembedding for each port from touchstone (s2p) files.
Read (download) and write (upload) files to and from the VNA
Examples on performing the following: - Performing a synchronous sweep - Saving a touchstone (snp) file - Saving trace data to a csv file
After performing the measurement as outlined in the section above, save screenshots of individual diagrams or the entire screen to file.
