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.
This parameter can be used to prevent unwanted trigger events due to fast power var-
iations.
