If you do impact testing for frequency response measurements, you may want to read the paper that was just added to the bibliography section at http://www.abravibe.com/bibliography.html! In this paper, written by Anders Brandt and Rune Brincker, presented at IMAC 2010, the time domain processing method which is implemented into ABRAVIBE was presented in some detail. Make sure to read this if you make FRF measurements using impact testing!
