Video (IF Envelope)

Pressing this key, when it is not selected, selects the video signal as the trigger. The Video trigger
condition is met when the video signal (the filtered and detected version of the input signal, including
both RBW and VBW filtering) crosses the video trigger level.
When the detector selected for all active traces is the average detector, the video
NOTE
signal for triggering does not include any VBW filtering.
The video trigger level is shown as a labeled line on the display. The line is displayed as long as video is
the selected trigger source.
Pressing this key, when it is already selected, accesses the video trigger setup functions.

The Status Operation Register bit 5 "Waiting for Trigger" is set at the same
time as the Sweeping or Measuring bit is set. It is cleared when the trigger
actually occurs (that is, after the trigger event occurs and all the applicable
trigger criteria have been met). A corresponding pop-up message ("Waiting
for trigger") is generated if no trigger signal appears after approximately 2 sec.
This message goes away when a trigger signal appears.
