Waveform Measurements VIs (Not in Base Package)

Use the Waveform Measurement VIs to perform common time and frequency domain measurements, such as DC, RMS, Tone Frequency/Amplitude/Phase, Harmonic Distortion, SINAD, and Averaged FFT Measurements.

Click the icons for VI descriptions.

Note  The VIs on this palette return an error if an input waveform has a dt less than or equal to zero.

Note  The Waveform Measurements VIs presently do not accept waveforms that contain complex data.

The VIs on this palette can return general LabVIEW error codes or specific waveform error codes.

Examples

Refer to the following VIs for examples of using the Waveform Measurements VIs:
