1. A hand-held apparatus for gathering and analyzing test data associated with rotating machines, the apparatus operable to be carried by an operator from one machine to another along a test route, the test data indicative of one or more operational characteristics of the rotating machines, the apparatus comprising:

  • a sensor input port for receiving a sensor signal from a sensor, the sensor signal indicative of one or more operational characteristics of the rotating machines;

    signal conditioning means for receiving the sensor signal, and for conditioning the sensor signal to produce a conditioned signal which is appropriate in format to be digitally processed;

    a processor coupled to the signal conditioning means for receiving and processing the conditioned signal according to processing instructions and processing parameters to produce a test spectrum, where the processing parameters correspond to one or more characteristics of the test spectrum;

    a memory device coupled to the processor for storing a plurality of executable test expert modules, each of the test expert modules containing the processing instructions for processing the conditioned signal in a particular way to determine one or more of the operational characteristics of the rotating machines;

    an operator input device coupled to the processor for receiving input from the operator to select one of the test expert modules to be executed to process the conditioned signal according to the processing instructions contained in the test expert module selected; and

    a display device for displaying the test results to the operator.
