304 Appendix A Command Reference
DSST
Digital Sync Separate Type
Class Format parameter setting - Digital video signal
Description Establishes the type of digital separate sync that appears at the digital HS and VS outputs
of the generator when digital composite sync is selected via the SSST command and the
outputs are gated on via the HSPG and VSPG commands. The only difference between
EIA and CCIR digital separate syncs is that, in the case of CCIR, the width of the vertical
sync pulse is 0.5 line shorter than the width specified via the VSPW command. In the EIA
case, the width of the vertical sync pulse is as programmed.
After sending the DSST command, send the FMTU or ALLU command.
