Using an Internal Source

By default, ao/SampleClock is created internally by dividing down the
ao/SampleClockTimebase. For more information, refer to the
Clock Timebase Signal
Several other internal signals can be routed to the sample clock. Refer to
Device Routing in MAX in the NI-DAQmx Help or the LabVIEW Help in
version 8.0 for more information.

Using an External Source

You can use a signal connected to any PFI or RTSI <0..6> pin as the source
of ao/SampleClock. Figure 3-6 shows the timing requirements of the
ao/SampleClock source.

Outputting the AO Sample Clock Signal

You can configure the PFI 5/AO SAMP CLK pin to output the
ao/SampleClock signal. The output pin reflects the ao/SampleClock
signal regardless of what signal you specify as its source.
