Trigger Offset
:TRIGger[:SEQuence]:OFFSet <64 bit floating point value>
:TRIGger[:SEQuence]:OFFSet?
This command sets the trigger offset.
Factory Preset
and *RST: 0 seconds
Example: :TRIG:SEQ:OFFS 1.0s
Range: Hardware specific; dependent upon the ADC being used,
current state, and the number of sweep points.
Default Unit: seconds
Remarks: 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 enable will
depend on the following parameters:
• Normal 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.
