Signal Analysis Express VIs (PDA Module)

Use the Signal Analysis Express VIs to perform waveform measurements, waveform generation, and signal processing.

Palette Object	Description
Convolution and Correlation	Performs convolution, deconvolution, or correlation on the input signals.
Create Histogram	Computes a histogram for Signal.
Curve Fitting	Computes the coefficients that best represent the input data based on the chosen model type.
Distortion Measurements	Performs distortion measurements on a signal, such as tone analysis, total harmonic distortion (THD), and signal in noise and distortion (SINAD).
Dual Channel Spectral Measurement	Performs a dual channel spectral measurement, such as frequency response, on input signals.
Filter	Processes signals through filters and windows.
Mask and Limit Testing	Performs limit testing on Signals. The Express VI compares Signals with upper and lower limits that you set.
Simulate Signal	Simulates a sine wave, square wave, triangle wave, sawtooth wave, or noise signal.
Spectral Measurements	Performs FFT-based spectral measurements, such as the averaged magnitude spectrum, power spectrum, and phase spectrum on a signal.
Statistics	Returns the selected parameter of the first signal in a waveform.
Tone Measurements	Finds the single tone with the highest amplitude or searches a specified frequency range to find the single tone with the highest amplitude. You also can find the frequency and phase for a single tone.
