The following figure shows the FD-116xx clock routing circuitry and timebases.
Figure 1. Clock Routing Circuitry
You can use the 13.1072 MHz
, 12.8 MHz
, 12.288 MHz
, and 10.24 MHz
timebases to generate the AI Sample Clock signals. These timebases are generated directly from the onboard clock generator.
By default, NI-DAQmx
automatically chooses the most suitable timebase for a selected data rate.
You can also manually select a timebase through the NI-DAQmx
Refer to the
FieldDAQ Timing Considerations and
Master Timebase Synchronization topics in the
NI-DAQmx Help for more information about configuring timing in the NI-DAQmx API.
