Trig Offset
On Off
Allows you to set and turn on or off an offset value from the trigger
point of the sweep at which to begin storing data in the trace of the
analyzer. The offset is specified as a function of time, and permits
positive (pre trigger) and negative (post trigger) values to be specified.

NOTE This function is only available when in Zero Span. (It is grayed out
when in swept span.) If this key is pressed in swept spans, the error
message: Trigger Offset unavailable in swept spans is displayed
in the status line. The value and state of Trigger Offset is remembered
if Zero Span is exited and restored when Zero Span is reselected.
NOTE This function is only available with Resolution Bandwidths of 1 kHz or
greater. If this key is pressed when the Resolution Bandwidths is less
than 1 kHz, the error message: Trigger Offset unavailable in
bandwidths < 1 kHz is displayed in the status line. While Trigger
Offset is on, it is not possible for the instrument to be set to a
Resolution Bandwidth less than 1 kHz. Any attempt to do so will cause
the error message: Bandwidths <1 kHz unavailable with Trigger
Offset on to be displayed in the status line.
