NI-DAQmx C Properties

Counter Output >> General Properties >> Counter Timebase >> Source

Data Type: char*
Description: Specifies the terminal of the timebase to use for the counter. Typically, NI-DAQmx uses one of the internal counter timebases when generating pulses. Use this property to specify an external timebase and produce custom pulse widths that are not possible using the internal timebases.

You can get/set/reset this property using:
  DAQmxGetCOCtrTimebaseSrc
  DAQmxSetCOCtrTimebaseSrc
  DAQmxResetCOCtrTimebaseSrc
