●
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.
9.5.2.2
Waiting for a Trigger Event
Before a trigger can be executed, the power sensor has to be set to the waiting for trig-
ger state. Depending on the required number of measurement cycles, you use one of
the following commands:
●
A new measurement cycle is started automatically after the previous one has been
terminated.
●
The number of measurement cycles is restricted.
If
1
is set, the command starts a single measurement cycle that
renders one result. Every time you send this command, a new measurement cycle
is started.
Otherwise, as many measurement cycles are performed as determined by the trig-
ger count.
9.5.2.3
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.
