VIDPic:DISpla
y {0|1|OF F|ON}
VIDPic:DISplay?
Arguments
1 or ON turns on the video picture display feature.
0 or OFF turns it off.
Examples
VIDP:DIS ON turns on the video picture display feature.
VIDPic:FRAMETYPe
Sets (or queries) the video picture frame type (ODD, EVEN or INTERLAced).
Interlaced frames combine successive odd and even frames by displaying
alternating lines from each. The resulting image has twice as many rows, which
changes its aspect ratio.
Conditions
MDO3000 series. Requires option SA3 or SA6 for the MDO4000C series.
Requires the DPO4VID application module for use with MSO/DPO4000B,
MDO4000 and MDO4000B models.

Syntax
VIDPic:FRAMETYPe {ODD|EVEN|INTERLAced}
VIDPic:FRAMETYPe?
Arguments
ODD sets the frame type to Odd.
EVEN sets the frame type to Even.
INTERLAced sets the frame type to Interlaced.
Examples
VIDP:FRAMETYP EVEN sets the video picture frame type to Even.
VIDPic:LOCation:HEIght
Sets (or queries) the video picture height, in rows.
Conditions
MDO3000 series. Requires option SA3 or SA6 for the MDO4000C series.
Requires the DPO4VID application module for use with MSO/DPO4000B,
MDO4000 and MDO4000B models.

Video Picture
Syntax
VIDPic:LOCation:HEIght <NR1>
VIDPic:LOCation:HEIght?
Arguments
Integer that represents the video picture height, in rows. This value must be >=
1. The range is from 1 - 400.
Examples
VIDP:LOC:HEI 253 sets the video picture height to 253 rows.
VIDPic:LOCation:OFFSet
Sets (or queries) the video picture line-to-line offset
. This is the amount of
additional delay time to add between lines of the video picture.
Conditions
MDO3000 series. Requires option SA3 or SA6 for the MDO4000C series.
Requires the DPO4VID application module for use with MSO/DPO4000B,
MDO4000 and MDO
4000B models.

Video Picture
Syntax
VIDPic:LOCation:OFFSet <NR3>
VIDPic:LOCation:OFFSet?
Arguments
Floating point number that represents the video picture
line-to-line offset in the
range of -63.5 microseconds to 63.5 microseconds, with a resolution 1.0E-10
(1.0 nsec). The default value is 56.6E-9.
Examples
VIDP:LOC:OFFS -63.5 sets the video picture line-to-line offset to
-63.5 microsecon
ds.
VIDPic:LOCation:STARt:LINE
Sets (or queries) the video picture starting line number.
Conditions
MDO3000 series. Requires option SA3 or SA6 for the MDO4000C series.
Requires the DPO4VID application module for use with MSO/DPO4000B,
MDO4000 and MDO4000B models.

Video Picture
Syntax
VIDPic:LOCation:STARt:LINE <NR1>
VIDPic:LOCation:STARt:LINE?
Arguments
Integer that represents the video picture starting line number, in the range of
0 to 1023. The default is 17.
Examples
VIDPIC:STAR:LINE 348 sets the video picture starting line number to 348.
VIDPic:LOCation:STARt:PIXel
Sets (or queries) the video picture starting pixel in each line
The range for this value varies with the instrument screen geometry. Each video
line is an analog signal of nominally 63.5us duration (10.9us blanking + 52.6us
active video) that can be sampled from 1MS/s to 100MS/s, giving from 52.6 to
5260 video samples or "pixels" per output line. The start pixel is the starting
sample in each line; it is limited to a single line at the current sample rate,i.e.
ranges between -10.9 to 52.6 and -1090 to +5260.
Conditions
MDO3000 series. Requires option SA3 or SA6 for the MDO4000C series.
Requires the DPO4VID application module for use with MSO/DPO4000B,
MDO4000 and MDO4000B models.

VIDPic:LOCation:STARt:PIXel <NR1>
VIDPic:LOCation:STARt:PIXel?
Arguments
Integer that represents the video picture starting pixel number. The default is 0.
Examples
VIDP:LOC:STAR:PIX 347 sets the video picture starting pixel number to 347.
VIDPic:LOCation:WIDth
Sets (or queries) the video picture width, in columns.
