ABSTRACT:
A system includes a phase sensor signal input for receiving a phase signal of a moving element of a machine; an analog-to-digital converter for converting the phase signal to a digital signal; and a storage system for saving the digital signal during an occurrence of an anomaly in operation of the machine. A related method includes obtaining a phase signal from a phase sensor that senses a phase of a moving element of a machine; converting the phase signal into a digital signal; and saving the digital signal during an occurrence of an anomaly in operation of the machine.
