This standard replaces GB/T 15472-1995 "distortion measurement instruments General technical requirements." This standard and GB/T 15472-1995 compared to the main changes are as follows. --- Increasing the digital display error calculation method for the measurement results (see 6.3.1.2, 6.3.2.2). --- Interface functions have increased the degree of distortion meter corresponding technical provisions and test methods (see 5.2.3, 6.3.3). The standard proposed by the Ministry of Industry and Information Technology of the People's Republic of China. This standard by the National Standardization Technical Committee Electronic Measuring Instruments (SAC/TC153) centralized. This standard was drafted. Chengdu Qianfeng Electronics Instrument Factory. The main drafters of this standard. Chen Lu onwards, Feng Wensheng, Linhuai Xi. This standard superseded standard previously issued as follows. --- GB/T 15472-1995. Distortion meter general specification1 ScopeThis 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.2 Normative referencesThe following documents for the application of this document is essential, dated references, only the dated version suitable for use herein Member.

General requirements3 Terms and DefinitionsThe following terms and definitions apply to this document. 3.1 Fundamental 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 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 amplitude-frequencydistortion 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 phase-frequencydistortion 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. ...... |
