Claim 13:
14. A method implemented by a computer processor for configuring a vibration data collection device to acquire machine vibration data from a machine for use in generating a vibration spectrum having amplitude peaks at a plurality of fault frequencies that are indicative of faults in the machine, wherein the machine includes components that rotate at a turning speed, the method comprising the following steps performed prior to acquiring the machine vibration data using the vibration data collection device:
(a) determining a maximum frequency of data collection;
(b) determining a minimum frequency spacing within the plurality of fault frequencies;
(c) based on the maximum frequency and the minimum frequency spacing, determining a number of lines of resolution of data collection according to, N
