Trigger Timeout
Sets a time after which an initiated measurement must have received a trigger event. If
no trigger event is received, a trigger timeout is indicated in manual operation mode. In
remote control mode the measurement is automatically stopped. The parameter can
be disabled so that no timeout occurs.
This setting has no influence on "Free Run" measurements.
Remote command:
Minimum Trigger Gap
Defines a minimum duration of the power-down periods (gaps) between two triggered
power pulses. This setting is valid for an "(IF) Power" trigger source.
The trigger system is controlled by means of a timer which is reset to zero in the follow-
ing instances:
●
At the IF power-down ramp of each triggered or untriggered pulse, even though the
previous counter may not have elapsed yet. A power-down ramp is detected when
the signal power falls below the trigger threshold.
●
At the beginning of each measurement: The minimum gap defines the minimum
time between the start of the measurement and the first trigger event.
The trigger system is re-armed as soon as the timer has reached the specified mini-
mum gap.
The "Minimum Trigger Gap" can be used to prevent unwanted trigger events due to
fast power variations.
Remote command:
3.3.8 Multi Evaluation: Limit Settings
The "Limits" in the multi evaluation configuration dialog define lower and/or upper limits
for the modulation, code domain and spectrum results. For details see
