Harmonics from Periodic Waveform Capture

Category: PMI Products, Analyzing Waveforms, Box Recorder, Eagle

Harmonics are usually recorded as interval (stripchart) data in PMI recorders. Each desired harmonic is recorded as a min/ave/ max stripchart trace, for each desired voltage and current channel. Although this gives a very complete picture of harmonic levels versus time, it can be memory intensive, and present much more data than may be needed. An alternative is to enable periodic waveform capture, and analyze the harmonics from the captured waveforms. The advantages of this method, and recommended settings and methods for using periodic waveform capture for harmonic analysis are presented here.

The traditional method for recording harmonics in a PMI recorder is through stripcharts.
