The Klippel TRF-Pro (Transfer Function Measurement + Rub and Buzz analysis) software module is identical to the TRF with the added capability of analyzing impulsive distortion.

Some examples of impulsive distortion are Rub & Buzz, voice coil bottoming, loose particles and other loudspeaker defects. The results are displayed in a color-coded graph showing displacement vs. frequency with the color representing the level of impulsive distortion.
