PQMPC can perform a harmonic analysis on any of the four current inputs or any of the three voltage inputs by
placing the PQM in a high speed sampling mode (256 samples/cycle) where it will sample one cycle of the user
defined parameter. PQMPC then takes this data and performs a FFT (Fast Fourier Transform) to extract the
harmonic information. The harmonic analysis feature is implemented into PQMPC as shown below.
1. Select the
