as a measurement result. Thus, the measurement result is a moving average of the
last partial measurements. How many of the partial measurements are averaged is
defined by the average count.
Useful if you want to detect trends in the result during the measurement.

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.
7.3.1
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.
7.3.2
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.

Remote commands to initiate the measurement
"Hold"
Waits for a trigger event. Press [1Trig] to trigger
the measurement.
Depending on the sensor type, the trigger is exe-
cuted by the trigger bus or by remote command.
See the user manual of the power sensor for
