6.1.3 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.
6.1.3.1 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.
6.1.3.2 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.
Trigger source Description 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
details.
TRIGger<Measurement>[:IMMediate]
"Immediate" Measures immediately, does not wait for trigger
condition. -
"Internal" Uses the input signal as trigger signal.
TRIGger<Measurement>[:IMMediate]
"Internal A" , "Inter-
nal B" , "Internal C" ,
"Internal D"
Receives the trigger signal from the trigger
sender. The trigger sender is the sensor connec-
ted to port
A, B, C, or D. See "Trigger Sender
State" on page 68.
TRIGger<Measurement>[:IMMediate]
"External" Uses the external trigger signal that is supplied at
the Trig In / Out
2 connector. See Chap-
ter 3.2.2.1, "Trig In / Out 2 and Out 1 / Trig Out
connectors" , on page 30.
