* For Gaussian White Noise, the maximum output voltage is limited to 1V instead of 2V.
The distribution of this type of noise can exceed the nominal requested amplitude. A
maximum of 1V for the nominal amplitude allows avoiding the saturation for an output with
a dynamic range of 2V.
** This value is for a block length of 4096 (or 2048 FFT number of lines). This is the
maximum amplitude at each frequency. With this maximum amplitude for each frequency
of the noise, the signal will cover the entire output dynamic of 2V.
This control allows specifying the block length during the wave file generation. This control
is especially important for the pseudo-random noise. Effectively, to take advantage of the
pseudo-random noise, the acquisition block length must fit the generator block length.
When all output signal parameters are set and the output file path is specified, the user
can click on the Generate .wav button to create the wave file.
These buttons allow saving and recalling the complete set-up of the wave generator. Also,
when the Generate .wav button is used, the wave generator interface creates a .wgs file
that contains the generator set-up in the same folder as the wave file to be created. This
can be useful for determining the contents of a wave file generated by this module.
Note: The post-processing module can be used to apply some treatment on the output
wave file. For instance, a high pass filter can be applied to a white noise to remove the low
frequencies. To do that, simply open the wave file with the post-processing module (see
section 5.0 for more details).
