4.11.8 Trig Delay
Allows you to control a time delay during which the analyzer will wait to begin a sweep
after receiving an external or line trigger signal. You can use negative delay to pre-trigger
the instrument.
NOTE Trigger Delay is not available in Free Run, so turning Free Run on turns off
Trigger Delay, but preserves the value of Trigger Delay.

4.11.9 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
