1 Scope

This standard specifies the distortion meter (hereinafter referred to as distortion meter) terms, product classifications, requirements, test methods, inspection rules, marking,

Packaging, transportation and storage.

This standard applies to harmonic distortion measurement instruments, as product design, the technical basis for the identification, production, use, testing, and also the development of distortion

Instrument product standards basis.

This standard also applies to low-voltage integrated measurement devices and harmonic distortion measurement unit.

This standard does not apply to non-linear intermodulation distortion and transient distortion meter measuring instrument.

3 Terms and Definitions

The following terms and definitions apply to this document.

3.1 Fundamental

Non-sinusoidal periodic signal converted by Fourier series analysis, which is composed of a plurality of different amplitudes, different frequencies of the sinusoidal signal consisting of

Of which the non-sinusoidal signal with the same frequency signal called the fundamental signal, its frequency is called the fundamental frequency.

3.2 Harmonic

Non-sinusoidal periodic signal by Fourier transform analysis series, which is composed of the fundamental signal and a number of different amplitude and frequency of the fundamental frequency

An integer multiple of the sine wave signal component. The latter are called harmonic signal having a frequency are called harmonic frequencies.

3.3 Amplitude-frequency distortion

Non-sinusoidal signal after transmission network, since the network is non-sinusoidal signal fundamental component and harmonic components have unequal

Gain response, thus the output signal waveform change, this change is called linear waveform amplitude-frequency distortion.

3.4 Frequency phase distortion

Non-sinusoidal signal after transmission network, since the network is non-sinusoidal signal fundamental component and harmonic components have different

The phase delay (lead or lag), so that the output signal waveform change, this change is called linear phase-frequency waveform distortion.
