Standard
Selects the TV standard or "Custom" for user-defined signals.
The standards PAL, PAL-M, NTSC and SECAM are available in the instrument firm-
ware. All other standards require the advance trigger option R&S RTH-K19.
HDTV standards are indicated by the number of active lines, the scanning system (p
for progressive scanning, i for interlaced scanning) and the frame rate. For interlaced
scanning, the field rate is used instead of the frame rate. 1080p/24sF is an HDTV stan-
dard using progressive segmented frame scanning.
"Custom" can be used for signals of other video systems, for example, medical dis-
plays, video monitors, and security cameras. To trigger on these signals, you have to
define the pulse type and length of the sync pulse, the scanning system and the line
period.
Remote command:
TRIGger:TV:STANdard on page 315
Signal Polarity
Sets the polarity of the signal. Note that the sync pulse has the opposite polarity, for
example, a positive signal has a negative sync pulse.

Mode
