At the moment, only one oscilloscope is controlled.
Its time base is the switching frequency (e.g. 10 us period)
with 4 analog signals.
Another oscilloscope can be useful and is added, to keep track of timing sequences:
DC bus ramp up
Duration of each phase shift (current) step
Time stamping of DMM triggering and measurements
DC bus ramp down
Such a time frame is in the 1s range or a bit below.
Consider reusing the same oscilloscope class and add a second oscilloscope in the supervisor script
