Select Sync Signal Type
Format parameter setting
SSST <type>
<type>
0 = no sync
1 = digital separate horizontal & vertical sync ( DHS &
DVS )
2 = digital separate composite sync ( DCS )
3 = analog composite sync ( ACS )
SSST?
<type>
The SSST command selects the type of sync signal that's used
to synchronize the display. In general, any one of three different
types of sync can be selected to synchronize the display. The
availability of different sync types is specified using the ASCT,
DSCT, and DSST commands. Some displays may not accept one
(or more) types of sync. For example, a digital video monitor
cannot accept analog composite sync because analog signal
transmission is not used. Also, a PGA display cannot accept
digital separate HS & VS because only one sync wire is provided
in the cabling. In these cases, one (or more) of the sync types
(ASCT, DSCT, or DSST) is set to zero (0) indicating that they
are not supported. If a non-supported sync type is selected using
the SSST command, then the corresponding sync outputs of the
generator will remain disabled. The SSST? query returns the
type of sync (if any) that's currently selected.
The desired sync type select must not be set to void with the
ASCT, DSCT, or DSST commands. To actually output the selected
sync signal it must be gated on with the appropriate ASSG,
ASBG, ASGG, ASRG, CSPG, HSPG and VSPG settings.
