Query Syntax: ASCT?
Query Response: <type>
Description: The ASCT command sets the kind of composite sync added to
the analog video outputs when analog sync is enabled (see SSST
command) and an analog video signal is being generated (see
AVST command). The ASCT? query returns the current setting
of ASCT. A setting of zero (0) indicates that the ACS sync selection
cannot be activated by the operator.
Other Required Cmds: The SSST mode must be set to 4, 5, 6, or 7 and the AVST type
must be set to 1, 2 or 5 in order for the ASCT setting to have
any affect on the generator’s hardware outputs. 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: ASCT 2 // Enable Amer ORed comp sync
// in buffer
SSST 4 // Enable ACS
AVST 2 // Select analog RGB as video
// type
FMTU // Update hardware to current
// buffer contents
