Figure 6-1: Trigger on all lines of a PAL signal with positive signal polarity, trigger level = 300 mV
Standard
Selects the TV standard or "Custom" for user-defined signals.
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<m>:TV:STANdard on page 1295
Mode
Selects the lines or fields on which the instrument triggers. Available modes depend on
the scanning system of the selected standard.
"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.
