HPE6432_SetVxiTriggerOutput
ViStatus HPE6432_SetVxiTriggerOutput (ViSession
instrumentHandle, ViUInt16 trigOutVXIBackplane);
Purpose
This function controls whether the Trig Out trigger is off or is sent to
one of the eight-shared VXI backplane TTL triggers
(TTLTRG0-TTLTRG7).
The Trig Out trigger is an output trigger and is produced after each
new hardware frequency or power level setting has settled; the value of
the dwell time controls how long the trigger outputs (Sync Out trigger
and Trig Out trigger) are asserted.
The Trig Out trigger can be directed to the Trig 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.
Allowable values:
Factory Preset Value: VXI_OUT_OFF

VXI Backplane TTL
Trigger
The Trig 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 Trig Out trigger is output to the
VXI backplane. The Trig Out trigger
may still be output to the hardware
front panel using
HPE6432_SetExtTriggerOutput.
