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
