Once I recreate the CMU200-based calibration procedure and write some
programs to automate it so I can ship FreeCalypso devices with per-unit
calibration like the historical commercial Calypso device manufacturers
Not sure if this helps, but we're planning to open-source our Python
framework we use to run various post-manufacturing tests/calibrations for
our base stations. It's designed as a very generic framework, but we also
implemented CMD57 flavor of SCPI commands for a completely automated
procedure. I expect CMU200 to have write different SCPI command set, but it
might be a good start. Let me know if that's something you might be
That said, the first step is always to get things working in a manual mode,
and automate them later.
Keep the good work!
