DKM-430 User Manual Rev_02 Firmware V-1.8

K92D01-EN - 21 -

The harmonic analyzer consists on a Fast Fourier Transform (FFT) algorithm which is run twice a second on
the selected channel.

The sample memory is 1024 samples length and 13 bits resolution with a sampling rate of 2048 s/s.

The unit is able to analyze up to 900Hz and up to 17th harmonic, whichever is smaller.

Alphanumeric Harmonics Table

All harmonics are displayed with 0.1% resolution.

On RainbowPlus program, harmonics and waveform are displayed on a single screen with more resolution.
