DSST?
<type>
The DSST command establishes the type of digital separate sync
that appears at the digital HS & 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. The DSST? query returns the current setting
of DSST. A setting of zero (0) indicates that separate digital
H&V sync cannot be activated by the operator.
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.
