Using an Internal Source
One of the following internal signals can drive ao/SampleClock.
• AO Sample Clock Timebase (divided down)
• Counter n Internal Output
A programmable internal counter divides down the AO Sample Clock
Timebase signal.
Using an External Source
Use one of the following external signals as the source of ao/SampleClock:
• Input PFI <0..5>
• RTSI <0..7>
• PXI_STAR
Routing AO Sample Clock Signal to an Output
Terminal
You can route ao/SampleClock (as an active low signal) out to any output
PFI <6..9> or RTSI <0..7> terminal.
Other Timing Requirements
A counter on your device internally generates ao/SampleClock unless you
select some external source. ao/StartTrigger starts the counter and either the
software or hardware can stop it when a finite generation completes. When
using an internally generated ao/SampleClock, you also can specify a
configurable delay from ao/StartTrigger to the first ao/SampleClock pulse.
By default, this delay is two ticks of ao/SampleClockTimebase.
