Analog Output Timing Options
M Series devices feature the following AO (waveform generation) timing signals:
•
•
•
•
AO Sample Clock Timebase Signal
AO Start Trigger Signal
Use the AO Start Trigger (ao/StartTrigger) signal to initiate a waveform generation. If you do
not use triggers, you can begin a generation with a software command.
Using a Digital Source
To use AO Start Trigger, specify a source and an edge. The source can be one of the following
signals:
•
A pulse initiated by host software
•
PFI <0..15>
•
RTSI <0..7>
•
AI Reference Trigger (ai/ReferenceTrigger)
•
AI Start Trigger (ai/StartTrigger)
•
PXI_STAR
The source also can 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.
