Waveform Generation Timing Signals

Waveform Generation Timing Summary

There is one AO Sample Clock that causes all AO channels to update simultaneously. Figure 3-3
summarizes the timing and routing options provided by the analog output timing engine.

AO Start Trigger Signal

You can use the AO Start Trigger (ao/StartTrigger) signal to initiate a waveform generation. If
you do not use triggers, you begin a generation with a software command.
