Analog Output Triggering; Connecting Analog Output Signals - National Instruments M Series User Manual

Non-buffered—In non-buffered acquisitions, data is written directly to the DACs on the
•
device. Typically, hardware-timed, non-buffered operations are used to write single
samples with good latency and known time increments between them.
Note (NI USB-62
hardware-timed operations.

Analog Output Triggering

Analog output supports two different triggering actions:
• Start trigger
• Pause trigger
An analog or digital trigger can initiate these actions. All M Series devices support digital
triggering, but some do not support analog triggering. To find your device's triggering options,
refer to the specifications document for your device. Refer to the
AO Pause Trigger Signal
sections for more information about these triggering actions.

Connecting Analog Output Signals

AO <0..3> are the voltage output signals for AO channels 0, 1, 2, and 3. AO GND is the ground
reference for AO <0..3>.
Figure 5-2 shows how to make AO connections to the device.
