Every measurement is started by a trigger event. Due to the chopper phases, one
measurement lasts twice the defined aperture time. During each measurement, the
trigger synchronization is high (TRIGger:SYNC:STATe ON). Every measurement pro-
vides a result. During the settling phase, the amount of the result is already correct, but
the noise is higher. After 4 measurements, when the average count is reached, settled
data are available.
When the trigger count is reached (TRIGger:COUNt on page 79), the power sensor
returns to the idle state.
