TestProcess.Source.Ratio.Distortion.Harmonic.AC.Sinewave

A test process that generates two signals representing a primary source signal and it’s Nth harmonic at a lower voltage level.  The two signals combined are designed to simulate harmonic distortion of a sinewave signal based on the Frequency and Volts RMS of the primary frequency and HarmonicFrequency and HarmonicVolts of the second signal.

This test is used to test the accuracy of a distortion meter or other similar device.

Required Parameters

  • Frequency – Frequency of the primary signal
  • Volts – Volts RMS of the primary signal
  • HarmonicFrequency – Frequency of the harmonic/second signal
  • HarmonicVolts – Volts RMS of the harmonic/second signal

Optional Parameters

  • Impedance – Output Impedance (50 Ohms assumed)
  • UUT.Input – Input Name of the UUT Connecting Point

Output Value & Uncertainty

    • Percent – % of distortion or THD
    • Distortion Level – dB
