Trig

Trig Delay On Off Allows you to set and turn on or off a delay, during which the analyzer

will wait to begin a sweep after receiving an external trigger signal.

This function is not available when

Gate is on.

NOTE This function is not available in Free Run or Video Trigger modes.

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 < 1kHz 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.
