Claim 0:
1. 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) specifying a number N of harmonics of the turning speed and a number M of harmonics of the plurality of fault frequencies to be included in the vibration spectrum;
(b) calculating N number of turning speed frequencies associated with the N number of harmonics of the turning speed;
(c) calculating M number of fault frequencies associated with the M number of harmonics of the plurality of fault frequencies;
(d) determining a maximum frequency of data collection based at least in part on a highest frequency of the N number of turning speed frequencies and the M number of fault frequencies;
(e) determining a minimum frequency spacing within the N number of turning speed frequencies and the M number of fault frequencies;
(f) based on the maximum frequency and the minimum frequency spacing, determining a number of lines of resolution that will allow identification of all of the amplitude peaks associated with each of the plurality of fault frequencies that are resolvable given limitations of the vibration data collection device; and
(g) configuring the vibration data collection device using the maximum frequency and the number of lines of resolution.
