"All fields"
Triggers on the first video line of the frame (progressive scanning) or
field (interlaced scanning), for example, to find amplitude differences
between the fields.
"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 segmented frame scanning (1080p/24sF).
They can be used, for example, to analyze the components of a video
signal.
"All lines"
Triggers on the line start of all video lines, for example, to find maxi-
mum video levels.
"Line number"
Triggers on a specified line. Enter the line number in "Line #".
Remote command:
TRIGger:TV:MODE on page 320
Line #
Sets the number of the line to be triggered on if "Mode" is set to "Line number". 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 "Field" (odd or even), and the line number in the field.
Remote command:
TRIGger:TV:LINE on page 321
TRIGger:TV:LFIeld on page 321
Trigger Level
Sets the trigger level as threshold for the synchronizing pulse. Make sure that the trig-
ger level crosses the synchronizing pulses of the video signal.

3.6.5.2 Settings for Custom Video Signals (R&S RTH-K19)
In addition to the standard TV trigger settings, triggering on custom video signals
requires a few more settings that describe the signal.
