The measurement is started by the trigger event. Due to the chopper phases, one
measurement lasts twice the defined aperture time. As defined by the average
count, after 4 measurements, the result is averaged and available. During the
whole measurement cycle, the trigger synchronization is high (
TRIGger:SYNC:
STATe ON
).
