Description: Specifies in seconds the length of time to measure the period of the signal if Method is DAQmx_Val_HighFreq2Ctr. Measurement accuracy increases with increased measurement time and with increased signal frequency. If you measure a high-frequency signal for too long, however, the count register could roll over, which results in an incorrect measurement.
