Vertical Sync Pulse Delay
Format parameter setting
VSPD <lines>

min
0 (when SCAN = 1) or
1 (when SCAN = 2)
max
VTOT-VRES-VSPW (when SCAN = 1) or
[(VTOT-VRES-1) /2]-VSPW (when SCAN = 2)
VSPD?
<lines>
The VSPD command establishes the delay between leading edge
of blanking in the first (or even) field and the leading edge of
the vertical sync pulse. When interlacing, delay between end of
video and leading edge of vertical sync before second (or odd)
field is 0.5 line shorter than the whole-line delay specified. The
VSPD? query returns the current setting of the vertical sync
pulse delay.
The FMTU command instructs the generator to use the new
setting. The ALLU command updates hardware to the new setting
and redraws the test image.

Vertical Sync Pulse Gate

VSPG?
<mode>
The VSPG command enables and disables the digital vertical
sync output. The VSPG? query returns the current mode of VSPG.
In order to use digital vertical sync, digital separate H&V sync
must be selected with the SSST command. The FMTU command
instructs the generator to use the new setting. The ALLU
command updates hardware to the new setting and redraws
the test image.
