Example: Moving termination control
Further settings for this example:
●
[SENSe<Sensor>:]AVERage:TCONtrol MOVing
●
TRIGger:COUNt 16
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 is available.
When the trigger count is reached (
TRIGger:COUNt
on page 75), the power sensor
returns to the idle state.
