Configuring Special Sync For Fs, Ls, Or Cs - Quantum Data 881 User Manual

Configuring special sync for FS, LS, or CS

882 Video Test Instrument User Guide (Rev A.35)
The special sync output can provide frame sync, line sync, or composite sync signals. The
output is controlled by setting parameters of these signals using the command line
interface. The following commands are used to set the special sync signal:
• FSPG - Frame sync
• PSPG - Probe signal
• LSPG - Line sync
• CSPG - Composite sync
Note: The special sync output is disabled whenever these parameters are set to zero.
A frame pulse can be generated and output at the beginning of each frame. In the case of
interlaced video, the frame pulse is output at the beginning of the blanking interval (of the
first field) that immediately precedes the top line of active video.
