FUNCTION REFERENCE

TV TRIGGER

Description:

In addition to edge and glitch triggering (explained under TRIGGER MAIN TB), there are extensive video triggering possibilities. These enable stable triggering on video frames and lines from various TV standards. There is no need to adjust the trigger level.

Triggering is possible on video signals with positive (pos) or negative (neg) signal polarity. Supported video standards include NTSC, PAL, SECAM, and HDTV. For HDTV systems a three- level sync trigger is used, and the line count of the system may be selected.

The MAIN TB can be triggered on a TV line (all lines are superimposed), or field 1 or field 2 of any of the four channels. In the field mode, the TRACK control can be used select triggering on any specific TV line for individual line display.

The TV trigger settings are selected from the menu under the TRIGGER menu key. TV trigger is not available when the optional External Trigger is selected as trigger source.

Note: A trigger edge can not be selected
