NI-DAQmx C Properties

Counter Output >> General Properties >> Counter Timebase >> Rate

Data Type: float64
Description: Specifies in Hertz the frequency of the counter timebase. Specifying the rate of a counter timebase allows you to define output pulses in seconds rather than in ticks of the timebase. If you use an external timebase and do not specify the rate, you can define output pulses only in ticks of the timebase.

You can get/set/reset this property using:
  DAQmxGetCOCtrTimebaseRate
  DAQmxSetCOCtrTimebaseRate
  DAQmxResetCOCtrTimebaseRate
