Chapter 5 Analog Output

Using a Digital Source
To use ao/Pause Trigger, specify a source and a polarity. The source can be
an external signal connected to any PFI or RTSI <0..6> pin. The source can
also 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 in
version 8.0 or later for more information.
Also, 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. For more information,
refer to the Triggering with an Analog Source section of Chapter 11,
Triggering.
Getting Started with AO Applications in Software
You can use the S Series device in the following analog output
applications:
• Single-point generation
• Finite generation
• Continuous generation
• Waveform generation
You can perform these generations through DMA, interrupt, or
programmed I/O data transfer mechanisms. Some of the applications also
use start triggers and pause triggers.
Note For more information about programming analog output applications and triggers in
software, refer to the NI-DAQmx Help or the LabVIEW Help in version 8.0 or later.
