Trigger Offset - Agilent Technologies ESA-E Series Programmer's Manual

Language Reference
TRIGger Subsystem
This command activates the trigger condition that allows the next
sweep to start when the external voltage (connected to GATE
TRIG/EXT TRIG IN on the rear panel) passes through approximately
1.5 volts. The external trigger signal must be a 0 V to +5 V TTL signal.
This function only controls the trigger polarity (for positive or
negative-going signals).

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
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.
