The  vibration  measurements  are  now  in  the  angular


        domain as compared to the former time domain.


        Once in the angular domain, an FFT can be performed on


        the  angular  domain  vibration  measurement  to  produce


        what is known as an order spectrum.


        Need to trigger the spectrum analyser with a pulse from a


        tachometer.
