7 Trigger Functions
Trigger
Remote Command :TRIGger[:SEQuence]:DELay <time>
:TRIGger[:SEQuence]:DELay?
:TRIGger[:SEQuence]:DELay:STATe OFF|ON|0|1
:TRIGger[:SEQuence]:DELay:STATe?
Example TRIG:DEL 1 ms
Preset 1 us
State Saved Saved in instrument state
Backwards Compatibility
Notes In ESA/PSA, the Trigger Delay was global to all triggers. In the X-Series, the delay can be set
individually for each Trigger Source. For backward compatibility, the global DELay command
updates all instances of trigger slope (VID, LINE, EXT1, EXT2) except TV and RFBurst. The query
returns the trigger delay setting of the currently selected trigger source.

Remote Command :TRIGger[:SEQuence]:OFFSet <time>
:TRIGger[:SEQuence]:OFFSet?
:TRIGger[:SEQuence]:OFFSet:STATe OFF|ON|0|1
:TRIGger[:SEQuence]:OFFSet:STATe?
Example TRIG:OFFS ON
TRIG:OFFS –100 ms
Notes These are ESA commands for trigger offset that allowed you to use a positive or negative delay when
in zero span and in a Res BW >= 1 kHz. For ESA compatibility, X-series analyzers keep track of this
offset and adds it to the Trigger Delay for VIDeo, LINE, EXTernal1 or EXTernal2 whenever the value is
sent to the hardware, if in Zero Span and RBW >= 1 kHz.
Preset Off, 0 s

External 1
Pressing this key, when it is not selected, selects an external input signal as the trigger. A new
sweep/measurement will start when the external trigger condition is met using the external 1 input
connector on the rear panel.
Pressing this key, when it is already selected, accesses the external 1 trigger setup menu.
