Analog Input
Using a Digital Source
To use AI Reference Trigger with a digital source, specify a source and an edge. The source can
be any of the following signals:
•
PFI <0..15>
•
RTSI <0..7>
•
PXI_STAR
•
PXIe_DSTAR<A,B>
•
Change Detection Event
•
Counter
n
Internal Output
•
DI Reference Trigger (di/ReferenceTrigger)
•
AO Start Trigger (ao/StartTrigger)
•
DO Start Trigger (do/StartTrigger)
The source can also be one of several internal signals on your DAQ device. Refer to
Device
Routing in MAX
in the
NI-DAQmx Help
or the
LabVIEW Help
for more information.
You can also specify whether the measurement acquisition stops on the rising edge or falling
edge of AI Reference Trigger.
Using an Analog Source
When you use an analog trigger source, the acquisition stops on the first rising edge of the
Analog Comparison Event signal.
Routing AI Reference Trigger Signal to an Output Terminal
You can route AI Reference Trigger out to any PFI <0..15>, RTSI <0..7>, PXI_Trig <0..7>, or
PXIe_DSTARC terminal.
All PFI terminals are configured as inputs by default.
AI Pause Trigger Signal
Note
(NI PXIe-6386/6396 Devices)
AI tasks do not support pause triggering on
PXIe-6386 and PXIe-6396 devices. For more information about special
considerations for these devices, go to
