Description
Syntax
Parameters
Command Example
VRAT?
Queries the vertical
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:
VSPW 3
ALLU
VSPP
Sets the polarity of the
vertical sync pulse.
VSPP <polarity>
VSPP?
<polarity>
Where polarity can be one of:
0 = high to low transition
1 = low to high transition
To set the horizontal sync pulse
polarity to low to high transition:
VSPP 1
ALLU
VSPG
Enables or disables
the vertical sync pulse.
VSPG <enable>
VSPG?
< enable >
Where enable is:
0 = disable
1 = enable
To enable the vertical sync
pulse:
VSPG 1
ALLU
VTOT
Sets the vertical total
number of lines of the
video timing.
VTOT <lines>
VTOT?
< lines >
Where lines are the total
number of lines.
To set the vertical total to 525
lines:
VTOT 525
ALLU
XVSI
Selects the interface.
XVSI <interface>
XVSI?
Where interface is one of:
2 – DVI (Computer)
3 – DVI (TV)
4 - HDMI
9 – Analog YPbPr or RGB)
To set the interface:
XVSI 4
ALLU
XVSG
Determines which
video components are
active when a format
is selected.
XVSG R G B
FMTU or ALLU
XVSG?
R G B
Where R G and B are:
R = 0 (Off) or 1 (On)
G = 0 (Off) or 1 (On)
B = 0 (Off) or 1 (On)
To set gate on or off red, green
or blue components:
XVSG 1 0 1 (Red On; Green Off;
Blue On)
ALLU
