4.10.9 Trig Offset (Remote Command Only)
This command sets the trigger offset. Trigger offset refers to the specified time interval
before or after the trigger event from which data is to be written to the trace, and then
displayed. Ordinarily, the trigger offset value is zero, and trace data is displayed beginning
at the trigger event. A negative trigger offset value results in the display of trace data prior
to the trigger event. A positive trigger offset value results in an effective delay in the
display of trace data after the trigger event.
The trigger offset value used when the feature is enabled will depend on the following
parameters:
Nominal trigger offset value originally entered
Specific instrument hardware in use
Sweep time
Number of sweep points
The effective trigger offset value will be re-calculated whenever any of these parameters
change.
State Saved: Saved in instrument state.
Factory Preset: 0 s
Range: Hardware specific; dependent upon the ADC being used, current state and
the number of sweep points.
History: Added with firmware revision A.02.00
Remote Command:
:TRIGger[:SEQuence]:OFFSet <time>
:TRIGger[:SEQuence]:OFFSet?
:TRIGger[:SEQuence]:OFFSet:STATe OFF|ON|0|1
:TRIGger[:SEQuence]:OFFSet:STATe?
Remote Command Notes: Trigger offset can only be turned on when in zero span and the
resolution bandwidth is 1 kHz or greater (non-digital bandwidths). Trigger
offset is available for all trigger modes.
Example: TRIG:OFFS 100 ms
TRIG:OFFS:STAT ON turns on the trigger offset.
