Sync Out
Sync Out
This is an output trigger (that can also be used as a marker) and is
asserted during dwell time; the value of the dwell time controls how
long the trigger outputs (Sync Out trigger and Trig Out trigger) are
asserted. The Sync Out trigger is produced after each point in the list
has settled if the point has a Sync Out bit enabled. This output trigger
can be directed to the Sync Out connector on the hardware front panel
or one of the eight-shared VXI backplane TTL triggers
(TTLTRG0-TTLTRG7) or both at the same time. This output trigger
can also be enabled when changing frequency or power or both in
set-spot mode or list mode.

syncOutFrontPanel Trigger
Description
Destination of Output Trigger
Sync Out The Sync Out trigger is present at the
Sync Out connector on the hardware
front panel of the synthesizer.
FRONT_OUT_POS = 16 Positive The Sync Out trigger is generated with a
positive polarity.
FRONT_OUT_NEG = 48 Negative The Sync Out trigger is generated with a
negative polarity.
FRONT_OUT_OFF = 0 Off No Sync Out trigger is output.

VXI Backplane TTL
Trigger
The Sync Out trigger is output to one of
the eight-shared VXI backplane TTL
triggers (TTLTRG0 - TTLTRG7). The VXI
backplane TTL triggers follow the
Synchronous Trigger Protocol as outlined
in the VXIbus Specification. This means
that the VXI backplane trigger line is
asserted low.
VXI_OUT_OFF = 15 Off No Sync Out trigger is output to the VXI
backplane. The Sync Out trigger may still
be output to the hardware front panel
using HPE6432_SetExtSyncOutput.
