Specifies the characteristics and performance of equipment for the measurement of radio disturbance voltages, currents and fields in the frequency range 9 kHz to 18 GHz. This Standard is identical with and has been reproduced from CISPR 16-1:1999-10.

This part of CISPR 16 is designated a basic standard, which specifies the characteristics and performance of equipment for the measurement of radio disturbance voltages, currents and fields in the frequency range 9 kHz to 18 GHz. In addition, requirements are specified for specialized equipment for discontinuous disturbance measurements. The requirements include the measurement of broadband and narrowband types of radio disturbance.The receiver types covered include the following:a) the quasi-peak measuring receiver,b) the peak measuring receiver,c) the average measuring receiver,d) the r.m.s. measuring receiver.In addition there are specifications for spectrum analyzers, scanning receivers and audio-frequency voltmeters. Specifications for ancillary apparatus are included for: artificial mains networks, current and voltage probes, absorbing clamp, antenna and test site, coupling units for current injection on cables, TEM cells, and reverberating chamber.The requirements of this publication shall be complied with at all frequencies and for all levels of radio disturbance voltages, currents, power or field strengths within the CISPR indicating range of the measuring equipment.Methods of measurement are covered in Part 2, and further information on radio disturbance is given in Part 3 of CISPR 16.
