Parameter:
<Polarity>
TRIGger:TV:MODE <Mode>
Selects the lines or fields on which the instrument triggers. Available modes depend on
the scanning system of the selected standard.
Parameter:
<Mode>
TRIGger:TV:LINE <LineNumber>
Sets the number of the line to be triggered on if
Usually the lines of the frame are counted, beginning from the frame start.
For NTSC signals, the lines are counted per field, not per frame. Therefore, you have
to set the odd or even field using TRIGger:TV:LFIeld, and the line number in the
field.
Parameter:
<LineNumber>
TRIGger:TV:LFIeld <LineField>
The line field (odd or even) is used as a reference for counting the video lines. Used by
the NTSC standard.

ALL | ODD | EVEN | ALINe | LINE
ALL
All fields: Triggers on the first video line of the frame (progres-
sive scanning) or field (interlaced scanning), for example, to find
amplitude differences between the fields.
ODD | EVEN
Odd fields / even fields: Triggers on the first video line of the odd
or even field. These modes are available for interlaced scanning
(PAL, PAL-M, SECAM, NTSC, 1080i) and progressive segmen-
ted frame scanning (1080p/24sF). They can be used, for exam-
ple, to analyze the components of a video signal.
ALINe
All lines: Triggers on the line start of all video lines, for example,
to find maximum video levels.
LINE
Triggers on a specified line. Specify the line number by using
TRIGger:TV:LINE.
