Trigger Offset
Defines the time offset between the trigger event and the start of the sweep.
offset > 0:
Start of the sweep is delayed
offset < 0:
Sweep starts earlier (pre-trigger)
For the "Time" trigger source, this function is not available.
Remote command:
Hysteresis
Defines the distance in dB to the trigger level that the trigger source must exceed
before a trigger event occurs. Settting a hysteresis avoids unwanted trigger events
caused by noise oscillation around the trigger level.
This setting is only available for "IF Power" trigger sources. The range of the value is
between 3 dB and 50 dB with a step width of 1 dB.
Remote command:
Drop-Out Time
Defines the time the input signal must stay below the trigger level before triggering
again.
Note:
For input from the Analog Baseband Interface (R&S
FSW-B71) using the base-
band power trigger (BBP), the default drop out time is set to 100
ns to avoid uninten-
tional trigger events (as no hysteresis can be configured in this case).
Remote command:
Slope
For all trigger sources except time and frequency mask (Realtime only) you can define
whether triggering occurs when the signal rises to the trigger level or falls down to it.
Remote command:
Trigger Holdoff
Defines the minimum time (in seconds) that must pass between two trigger events.
Trigger events that occur during the holdoff time are ignored.
Remote command:
5.5.2 Trigger Input and Output Settings
The trigger input and output settings are configured in the "Trigger In/Out" tab of the
"Trigger" dialog box, or in the "Outputs" configuration dialog box (via the INPUT/
OUTPUT key).
