Line Number Represents Count

In Generic mode, the line number represents the number of a count instead of a real line number. This is reflected in the label in the softkey changing from Line to Count. In the Mode softkey selections, Line:Field 1, Line:Field 2 and Count:Vertical are used to indicate where the counting starts. For an interlaced video signal, the counting starts from the rising edge of the first vertical serration pulse of Field 1 and/or Field 2. For a non-interlaced video signal, the counting starts after the rising edge of the vertical sync pulse.

Example exercises

The following are exercises to familiarize you with TV triggering. These exercises use the NTSC video standard.

To trigger on a specific line of video

TV triggering requires greater than 1/2 division of sync amplitude with any analog channel as the trigger source. Turning the trigger Level knob in TV trigger does not change the trigger level because the trigger level is automatically set to the sync pulse tips.
