*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
