Data Type: | float64 |
Description: | Specifies in seconds the length of time to measure the frequency 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. |
