rate (field rate for
interlaced formats) of
the outgoing video
format.
VRAT?
Not Applicable
To read the vertical rate of the
outgoing HDMI signal of
1080i30:
VRAT?
+60.000E+00
VSPD
Sets or queries the
vertical sync pulse
delay of the active
timing. Express in
number of lines.
VSPD < lines >
VSPD?
< lines >
Where lines can be within
the range of:
Min = 1 (if scan = 1)
= 2 (if scan = 2)
Max = VTOT – 1 (if scan = 1)
= VTOT – 3 (if scan =
2)
To set the horizontal sync
pulse delay:
VSPD 11
ALLU
VSPW Sets or queries the
vertical sync pulse
width of the active
timing. Express in
number of lines.
VSPW < lines >
VSPW?
< lines >
Where lines are the number
of lines for the vertical pulse
width
To set the horizontal sync
pulse width:
