Specification for radio disturbance and immunity measuring apparatus and methods. Part 1-4: Radio disturbance and immunity measuring apparatus – Antennas and test sites for radiated disturbance measurementsThe International Electrotechnical Commission has released a new CISPR 16 standard dealing with radio disturbance and immunity measuring apparatus and methods for antennas and test sites for radiated disturbance measurements.This part of CISPR 16 specifies the characteristics and performance of equipment for the measurement of radiated disturbances in the frequency range 9 kHz to 18 GHz. Specifications for antennas and test sites are included. The requirements of this publication apply at all frequencies and for all levels of radiated disturbances within the CISPR indicating range of the measuring equipment. Methods of measurement are covered in Part 2-3, and further information on radio disturbance is given in Part 3 of CISPR 16. Uncertainties, statistics and limit modeling are covered in Part 4 of CISPR 16.View a preview of this standard at the IEC Web site.
