HPE6432_SetVxiSyncOutput
ViStatus HPE6432_SetVxiSyncOutput (ViSession
instrumentHandle, ViUInt16 syncOutVXIBackplane);
Purpose
This function controls whether the Sync Out trigger is off or is sent to
one of the eight-shared VXI backplane TTL triggers
(TTLTRG0-TTLTRG7).
• To direct the Sync Out trigger to the hardware front panel of the
synthesizer, refer to the “Sync Out (Front Panel)” on page 3-53
function.
• 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 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:
syncOutVXIBackplane Trigger Description Destination of Output Trigger
VXI0 = 0
VXI1 = 1
VXI2 = 2
VXI3 = 3
VXI4 = 4
VXI5 = 5
VXI6 = 6
VXI7 = 7
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.
