The Klippel TRF software module measures transfer functions such as SPL with a microphone vs. input and displacement with laser vs. input, and others.

TRF provides the fundamental response as well as THD with individual harmonic components up to the 21st order. Results can be viewed in 2d graphs or waterfall plots to show cumulative decay spectrum, Wigner distribution and other types.
