Figure 5-3. Analog Output Timing Options
NI 6236 devices feature the following AO (waveform generation) timing
signals.
• AO Start Trigger Signal
• AO Pause Trigger Signal
• AO Sample Clock Signal
• 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/StartTrigger, specify a source and an edge. The source can be one
of the following signals:
• A pulse initiated by host software
• Input PFI <0..5>
• RTSI <0..7>
• ai/ReferenceTrigger
• ai/StartTrigger
• PXI_STAR
