Video Picture
Syntax
VIDPic:LOCation:Y <NR1>
VIDPic:LOCation:Y?
Arguments
Integer that represents the video picture Y origin location, in rows, whererow0is
the top most edge of the display. The range for this value is 0 - 399. The default is
73. [ = (400 - 254) / 2 ].
Examples
VIDP:LOC:Y 367 sets the video picture Y origin location to row 367.
VIDPic:SOUrce
Sets (or queries) the channel to use for the video picture source waveform.
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:SOUrce {CH1|CH2 |CH3|CH4}
VIDPic:SOUrce?
Arguments
CH1|CH2|CH3|CH4 specify which channel to use for the video picture source
waveform.
Examples
VIDP:SOU CH3 specifies to use Channel 3 as the source waveform.
VIDPic:STANdard
Sets (or queries) which video picture standard to use (either NTSC or PAL).

VIDP:STAN PAL sets the video picture standard to PAL.
*WAI (No Query Form)
Prevents the oscilloscope from executing further commands or queries until all
pending commands that generate an OPC message are complete. This command
allows you to synchronize the operation of the oscilloscope with your application
program.(See page 3-7, Synchronization Methods.)
The
*WAI command will stop execution until certain oscilloscope operations are
complete. (See Table 3-3 on page 3-8.)

WAVFrm? (Query Only)
This query returns the waveform preamble and the waveform data for the source
waveform specified by the
DATa:SOUrce command. This command is equivalent

to sending both
WFMOutpre? and CURVe?, with the additional provision that the
response to
WAVFrm? is guaranteed to provide a synchronized preamble and
curve. The source waveform, as specified by
DATA:SOURCE, must be active or
the query will not return any data and will generate an error event.
