The following table lists the characteristics of this property.

Short Name CI.Period.MeasMeth
Data type ci32.png
Permissions Read/Write
Resettable True
Settable While Task Is Running device-specific
Available in Run-Time Engine True
Low Frequency with 1 Counter 10105
Use one counter that uses a constant timebase to measure the input signal.
High Frequency with 2 Counters 10157
Use two counters, one of which counts pulses of the signal to measure during the specified measurement time.
Large Range with 2 Counters 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.
Dynamic Averaging 16065
Uses one counter with configuration options to control the amount of averaging or filtering applied to the counter measurements. Set filtering options to balance measurement accuracy and noise versus latency.
