This guidebook is intended to provide details on how to recognize common waveform patterns measured in the RF spectrum between 30 kHz and 100 MHz and give guidance on how these signatures can be used to identify expected results vs. defects including location and type being detected in the machine.
The common waveform patterns are arcing, corona, partial (gap) discharge, micro-sparking, and random noise. Some waveforms are combinations of the common patterns.
