CSPP

Composite Sync Pulse Polarity

Classification: Format parameter setting

Command Syntax: CSPP <polarity>

Limits: <polarity>

0= active-low (negative going pulse)

1= active-high (positive going pulse)

Query Syntax: CSPP?

Query Response: <polarity>

Description: The CSPP command establishes the logic sense of the digital composite sync output. The CSPP? query returns the current setting of CSPP.

Other Required Cmds: In order to use digital composite sync, it must be gated on with the CSPG command and selected with the SSST 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.
