:TRIGger:VIDeo:STANdard
:TRIGger:VIDeo:STANdard <standard>
:TRIGger:VIDeo:STANdard?
Sets or queries the video standard of Video trigger.
{PALSecam|NTSC|480P|576P}
 PALSecam:
PAL: indicates that the frame frequency is 25 frames per second. The TV scan line is
625, with the odd field going first and the even field following behind.
SECAM: indicates that the frame frequency is 25 frames per second. The TV scan line
is 625 with interlaced scan.
 NTSC: indicates that the field frequency is 60 fields per second, and the frame
frequency is 30 frames per second. The TV scan line is 525, with the even field going
first and the odd field following behind.
 480P: indicates that the frame frequency is 60 frames per second. The TV scan line is
525, with progressive scan; the line frequency is 31.5 kHz.
 576P: indicates that the frame frequency is 60 frames per second. The TV scan line is
625; with progressive scan.
The query returns PALS, NTSC, 480P, or 576P.
:TRIGger:VIDeo:STANdard NTSC /*Selects NTSC as the video standard.*/
:TRIGger:VIDeo:STANdard? /*The query returns NTSC.*/
:TRIGger:VIDeo:LEVel
:TRIGger:VIDeo:LEVel <level>
:TRIGger:VIDeo:LEVel?
Sets or queries the trigger level of Video trigger. The unit is the same as that of the
current amplitude.
(-5 × VerticalScale - OFFSet) to
(5 × VerticalScale - OFFSet)
For VerticalScale, refer to the :CHANnel<n>:SCALe command. For OFFSet, refer to
the :CHANnel<n>:OFFSet command.
The query returns the trigger level in scientific notation.
:TRIGger:VIDeo:LEVel 0.16 /*Sets the trigger level to 160 mV.*/
:TRIGger:VIDeo:LEVel? /*The query returns 1.600000E-1.*/
