DVSP
Digital Video Signal Polarity
Classification:
Format parameter setting
Command Syntax:
DVSP <polarity>
Limits:
<polarity>
0 = active-low (negative going video)
1 = active-high (positive going video)
Query Syntax:
DVSP?
Query Response:
<polarity>
Description:
The DVSP command establishes the logic sense of the digital
video outputs. The DVSP? query returns the current setting of
DVSP.
Note – Please note that digital video is not supported by all
generators in the 801G series. Also, some models that support
digital video may not support active low for the polarity.
Other Required Cmds:
In order to use the digital video outputs, digital video must be
enabled with the DVST command. The FMTU command instructs
the generator to use the new setting. The ALLU command updates
hardware to the new setting and redraws the test image.
