Do you want to output each new average value as a measurement result or do you
want to bundle more measured values into one result?

Triggering
In a basic continuous measurement, the measurement is started immediately after the
initiate command. However, sometimes you want that the measurement starts only if a
specific condition is fulfilled. For example, if a signal level is exceeded, or in certain
time intervals. For these cases, you can define a trigger for the measurement.
5.5.1
Trigger States
The power sensor has trigger states to define the exact start and stop time of a mea-
surement and the sequence of a measurement cycle. The following states are defined:
●
Idle
The power sensor performs no measurement. After powered on, the power sensor
is in the idle state.
●
Waiting for trigger
The power sensor waits for a trigger event that is defined by the trigger source.
When the trigger event occurs, the power sensor enters the measuring state.
●
Measuring
The power sensor is measuring data. It remains in this state during the measure-
ment. When the measurement is completed, it exits this state immediately.
5.5.2
Trigger Sources
The possible trigger conditions and the execution of a trigger depend on the selected
trigger mode and trigger source.
If the signal power exceeds or falls below a reference level set by the trigger level, the
measurement is started after the defined delay time. Waiting for a trigger event can be
skipped.
