Trigger Offset

Defines the time offset between the trigger event and the start of the sweep.
Offset > 0:
Offset < 0:
For the "Time" trigger source, this function is not available.
Remote command:
TRIGger[:SEQuence]:HOLDoff[:TIME]

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.
When using the optional 2 GHz bandwidth extension (R&S FSW-B2000) with an IF
power trigger, the hysteresis refers to the robust width trigger.
(For details see the R&S FSW I/Q Analyzer and I/Q Input User Manual.)
Remote command:
TRIGger[:SEQuence]:IFPower:HYSTeresis

Drop-Out Time

Defines the time the input signal must stay below the trigger level before triggering
again.
Note: For input from the optional Analog Baseband Interface using the baseband
power trigger (BBP), the default drop out time is set to 100 ns. This avoids uninten-
tional trigger events (as no hysteresis can be configured in this case).
When using the optional 2 GHz bandwidth extension (R&S FSW-B2000) with an IF
power trigger, the drop-out time defines the width of the robust width trigger. By default
it is set to 1 μs. For external triggers, no drop-out time is available when using the
B2000 option.
(For details, see the R&S FSW I/Q Analyzer and I/Q Input User Manual.)
Remote command:
TRIGger[:SEQuence]:DTIMe

Coupling

If the selected trigger source is "IF Power" or
pling of the external trigger to the oscilloscope.
This setting is only available if the optional 2 GHz bandwidth extension is active

Direct connection with 50 Ω termination, passes both DC and AC
components of the trigger signal.
Direct connection with 1 MΩ termination, passes both DC and AC
components of the trigger signal.
