Analog Input:Frequency:Voltage:Hysteresis Property

Short Name: AI.Freq.Hyst

Property of DAQmx Channel

Specifies in volts a window below AI.Freq.ThreshVoltage. The input voltage must pass below AI.Freq.ThreshVoltage minus this value before NI-DAQmx recognizes a waveform repetition at AI.Freq.ThreshVoltage. Hysteresis can improve the measurement accuracy when the signal contains noise or jitter.
