•DI Pause Trigger (di/PauseTrigger)
• DO Pause Trigger (do/PauseTrigger)
The source also can be one of several other 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 also can specify whether the samples are paused when AO Pause
Trigger is at a logic high or low level.
Using an Analog Source
When you use an analog trigger source, the samples are paused when the
Analog Comparison Event signal is at a high level. Refer to the Triggering
with an Analog Source section of Chapter 11, Triggering, for more
information.
Routing AO Pause Trigger Signal to an Output
Terminal
You can route AO Pause Trigger out to any PFI <0..15>, RTSI <0..7>, or
PXIe-DSTARC terminal.
AO Sample Clock Signal
Use the AO Sample Clock (ao/SampleClock) signal to initiate AO samples.
Each sample updates the outputs of all of the DACs. You can specify an
internal or external source for AO Sample Clock. You also can specify
whether the DAC update begins on the rising edge or falling edge of AO
Sample Clock.
Using an Internal Source
One of the following internal signals can drive AO Sample Clock:
• AO Sample Clock Timebase (divided down)
•Counter n Internal Output
• Change Detection Event
•Counter n Sample Clock
• AI Convert Clock (ai/ConvertClock)
• AI Sample Clock (ai/SampleClock)
• DI Sample Clock (di/SampleClock)
• DO Sample Clock (do/SampleClock)
