Use the Utilities VIs to generate signals for demonstration purposes or to access scale information in the time-frequency representation.

TFA Data Samples VI
Contains the demonstration data samples for the Time Frequency Analysis VIs.
TFA Read from File VI
Reads data from a spreadsheet text file that contains a 1D array, a 2D array, a byte stream file of single-precision numbers, a byte stream file of 16-bit signed integers, a file created with the Write Waveforms to File VI, a WAV file, a JPG file, a BMP file, or a PNG file.
TFA Gaussian Chirp Generator VI
Generates a summation of Gaussian chirps with different parameters.
TFA Configure Spectrogram Indicator VI
Displays the spectrogram of a signal on an intensity graph. Wire data to the color table input to determine the polymorphic instance to use or manually select the instance.
TFA Configure Coefficients Indicator VI
Displays the magnitude or phase of the linear time-frequency coefficients of a signal on an intensity graph.
TFA Get Time and Freq Scale Info VI
Gets the time scale information and the frequency scale information of the time-frequency representation.
TFA Set Time and Freq Scale Info VI
Sets the time scale information and the frequency scale information for the time-frequency representation.
