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.
Example
CSPG 1 // Enable dig comp sync in buffer
CSPP 1 // Select active hi in buffer
SSST 2 // Choose digital comp sync type in buffer
FMTU // Update hardware to current buffer contents
