HPE6432_SetExtSyncOutput
ViStatus HPE6432_SetExtSyncOutput (ViSession instrumentHandle,
ViUInt16 syncOutFrontPanel);
Purpose
This function controls the Sync Out trigger on the hardware front panel
of the synthesizer.
To direct the Sync Out trigger to one of the eight-shared VXI backplane
TTL triggers (TTLTRG0-TTLTRG7), refer to the “Sync Out (VXI
Backplane)” on page 3-54.
To control the Sync Out trigger in set-spot mode, refer to the Set Sync
Out (On/Off) function.
The Sync Out trigger 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.
Allowable values:

polarity.
FRONT_OUT_NEG = 48 The Sync Out trigger is generated with a negative
polarity.
