Command
Description
Syntax
Parameters
Command Example
HSPG
Sets enable gate of
the horizontal sync
pulse.
HSPG <enable>
HSPG?
< enable >
Where enable is:
0 = disable
1 = enable
To enable the horizontal sync
pulse:
HSPG 1
ALLU or FMTU
IMGL
Loads an image
(pattern).
IMGL <image>
Where image is one of the
images listed in Table 7-4
See example below for IMGU
IMGU
Activates an image
that has been loaded
and queries for the
currently active image.
IMGU
IMGU?
Not applicable
To load and invoke a image load
command:
IMGL SMPTEbar
IMGU
NBPC
Sets or queries the
number of bits per
component. Applies
only to HDMI
NBPC
<bit_depth>
NBPC?
Where bit_depth is one of:
8 – 8 bits per component
10 – 10 bit per component
12 – 12 bits per component
To set the HDMI bit depth to 10:
NBPC 10
ALLU or FMTU
PRAT?
Queries the pixel rate
of the outgoing HDMI
format.
PRAT?
Not Applicable
To read the pixel rate of the
outgoing HDMI signal:
PRAT?
+74.2500E+06
RGBW
Sets RGB values on
with Raster and
Window test patterns
RGBW <pattern>
<R> <G> <B>
RGBW?
<pattern> <R>
<G> <B>
Where pattern is either 4 for
Window pattern or 33 for raster
pattern.
Where R G B are the
respective values for the RGB
color components
To set the Window pattern to
dark brown:
imgl window
imgu
rgbw 4 115 82 68
or
rgbw 4 115 87 74
SCAN
Defines whether the
active timing is
progressive or
interlaced or queries
the state of the active
timing.
SCAN <scan>
SCAN?
< scan >
Where scan is:
1 = progressive
2 = interlaced
To set the scan to interlaced:
SCAN 2
ALLU or FMTU
SIRE
Sets IRE levels for
certain images:
Window1/2, Raster,
Flat_Wht/Grn/
Red/Blu/Cyn/Mag/Blk
SIRE <range>
Where range is a value from 0
to 100.
To set the IRE range for any of
the images listed:
SIRE 50
ALLU
SSST
Sets or queries the
sync type. Applies only
to analog outputs.
SSST
<sync_type>
SSST?
Where format_type is one of:
1 – separate sync
3 – sync on green
To set the analog sync type to
separate sync:
SSST 1
ALLU
VRES
Sets or queries the
vertical resolution of
the active timing.
Express in number of
lines.
VRES <lines>
VRES?
< 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 resolution:
VRES 480
ALLU
