Can EASERA perform distortion measurements?

Yes, it can.

EASERA implements a new method of measuring nonlinearities in the response of a system. By utilizing a pink sweep as an excitation signal, all of the distortion components are located at the end of the impulse response and can be separated by windowing.

After some post-processing the individual harmonic frequency responses can be viewed and even THD in a high frequency resolution can be computed. Of course also the K2, K3 K.. spectra are available.

Rather than running a long series of sinusoidal excitations, this new method allows to determine the impulse response, the transfer function and the nonlinearities with a single measurement.
