Waveform Measurements Use the Waveform Measurements VIs to perform common time and frequency domain measurements, such as DC, RMS, Tone Frequency/Amplitude/Phase, Harmonic Distortion, SINAD, and Averaged FFT Measurements.
Note The Waveform Measurements VIs presently do not accept waveforms that contain complex data.
The VIs on this palette can return waveform error codes . In addition, the VIs on this palette return an error if an input waveform has a dt less than or equal to zero.
Basic Averaged DC-RMS VI Averaged DC-RMS VI, but this VI returns only one DC value and one RMS value per input waveform.Averaged DC-RMS VI Basic Averaged DC-RMS VI, but this VI gives more precise control over the individual DC and RMS calculations.Cycle Average and RMS VI signal in input to determine the polymorphic instance to use or manually select the instance. Waveform Monitoring Transition Measurements VI signal in input to determine the polymorphic instance to use or manually select the instance. Pulse Measurements VI period , pulse duration (pulse width), duty cycle (duty factor), and pulse center of a selected pulse and period. Wire data to the signal in input to determine the polymorphic instance to use or manually select the instance. Reference and State Levels Amplitude and Levels VI amplitude , high state level , and low state level of a waveform or an array of waveforms. Wire data to the signal in input to determine the polymorphic instance to use or manually select the instance. Extract Single Tone Information VI time signal in input to determine the polymorphic instance to use or manually select the instance. Extract Multiple Tone Information VI threshold . Wire data to the time signal in input to determine the polymorphic instance to use or manually select the instance.Harmonic Distortion Analyzer VI signal in input to determine the polymorphic instance to use or manually select the instance.
