1. Create PyDSA.py …

   Updated version using Python 3.9 and latest PyVisa and NumPy
   
   The code is updated with more function and robust interaction with the scope.
   
   To use you should update to latest pyvisa (py -m pip install pyvisa)
   
   Install latest numpy in same manner
   
   Download PyDSA from the repo and off you go!
   
   *Changelog Rossi, KK1L January & July 2021
   
   Python 3.9 update...syntax, call format changes, functions
   More robust scope communication
   On screen progress feedback
   Warning if scope is not triggered (used to crash)
   Warning if input signal is clipping at scope
   Can read from channel 1 or channel 2
   Peak detect information and marker on waveform
   Added autoscaling
   Scaling change and offset works for all waves on the screen
   Can store up to 7 waveforms on the screen
   Most actions can be done while acquiring
   Added clear function which removes all waves and resets averaging/max-hold
   Scale is accurate in dBm after calibration *Previously the absolute level was arbitrary, but relatively accurate *"Calibrate" is manual operation to adjust peak for a known dBm value *Use a sine wave of known magnitude and adjust the calibration factor for the right reading Note: It is on my list to make this automatic.
   Added autocalibration. Use a known amplitude sine wave and autocal will match to the dBm you enter
