Repetition Interval
Defines the repetition interval for a time trigger. The shortest interval is 2 ms.
The repetition interval should be set to the exact pulse period, burst length, frame
length or other repetitive signal characteristic.
Remote command:
TRIGger[:SEQuence]:TIME:RINTerval on page 1055
Drop-Out Time
Defines the time the input signal must stay below the trigger level before triggering
again.
For more information on the drop-out time, see "Trigger Drop-Out Time" on page 478.
Remote command:
TRIGger[:SEQuence]:DTIMe on page 1050
Trigger Offset
Defines the time offset between the trigger event and the start of the sweep.
For more information, see "Trigger Offset" on page 477.
Offset > 0: Start of the sweep is delayed
Offset < 0: Sweep starts earlier (pretrigger)
Only possible for zero span (e.g. I/Q Analyzer application) and gated trigger switched off
Maximum allowed range limited by the sweep time:
Pretrigger
max
= sweep time
max
For the "Time" trigger source, this function is not available.
Remote command:
TRIGger[:SEQuence]:HOLDoff[:TIME] on page 1050
Hysteresis
Defines the distance in dB to the trigger level that the trigger source must exceed
before a trigger event occurs. Setting 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.
For more information, see "Trigger Hysteresis" on page 477.
Remote command:
TRIGger[:SEQuence]:IFPower:HYSTeresis on page 1051
