Valid values

DAQmx_Val_LowFreq1Ctr	10105	Use one counter that uses a constant timebase to measure the input signal.
DAQmx_Val_HighFreq2Ctr	10157	Use two counters, one of which counts pulses of the signal to measure during the specified measurement time.
DAQmx_Val_LargeRng2Ctr	10205	Use one counter to divide the frequency of the input signal to create a lower-frequency signal that the second counter can more easily measure.
