public enum CIPeriodMeasurementMethod


Member nameDescription
DynamicAveragingUses one counter and automatically configures the counter settings based on the range of frequencies to be measured. During the acquisition, the counter dynamically adjusts the number of periods that are averaged to balance measurement accuracy and latency.
HighFrequencyTwoCounterUse two counters, one of which counts pulses of the signal to measure during the specified measurement time.
LargeRangeTwoCounterUse one counter to divide the frequency of the input signal to create a lower-frequency signal that the second counter can more easily measure.
LowFrequencyOneCounterUse one counter that uses a constant timebase to measure the input signal.


Specifies the method to use to measure the period of the signal. Use this enumeration to get or set the value of PeriodMeasurementMethod.
