Teledyne LeCroy (Chestnut Ridge, NY) has introduced a new Harmonics Calculation option for the Motor Drive Analyzer (MDA800) series. This optional software adds advanced harmonic filtering for AC Input and Drive Output Numeric table measurements; Total Harmonic Distortion (THD) measurement parameters for voltage, current, and power; and a new Harmonic Order table with Spectral waveform displays. The standard Motor Drive Analyzer software provides either Full Spectrum (no harmonic filter applied) or Fundamental Only harmonic filters. The new option adds a Fundamental+N and a Range Filter. The Fundamental+N filter allows you to specify how many (N) harmonics from the fundamental to include in the Numerics table calculations. The Range filter allows you to specify a range starting point other than the fundamental.
