ViStatus HPE6432_SetTriggerInput (ViSession
instrumentHandle, ViUInt16 trigInSource);
Purpose
This function specifies the source of the Trig In trigger.
The source of the Trig In trigger can come from the hardware front
panel, the VXI backplane, a software function, or it can be disabled; it
can only come from one source at a time. Its functionality is determined
by the mode used during a Run List function.
Allowable values:
Factory Preset Value: IN_OFF
FRONT_IN_POS=
24
The Trig In trigger is asserted with a positive edge
polarity.
FRONT_IN_NEG

polarity.
VXI0=0 The Trig In trigger can come from any one of the
eight-shared VXI backplane TTL triggers
(TTLTRG0-TTLTRG7). The VXI backplane triggers
follow the Synchronous Trigger Protocol as outlined in
the VXIbus Specification. This means that the VXI
backplane trigger line must be asserted for at least
250 ns.
