Specification for radio disturbance and immunity measuring apparatus and methods - Part 2-3: Methods of measurement of disturbances and immunity - Radiated disturbance measurements

This part of CISPR 16 specifies the methods of measurement of radiated disturbance
phenomena in the frequency range of 9 kHz to 18 GHz. The aspects of measurement
uncertainty are specified in CISPR 16-4-1 and CISPR 16-4-2.
NOTE In accordance with IEC Guide 107 [13]1, CISPR 16-2-3 is a basic EMC publication for use by product
committees of the IEC. As stated in Guide 107, product committees are responsible for determining the
applicability of the EMC standard. CISPR and its subcommittees are prepared to co-operate with product
committees in the evaluation of the value of particular EMC tests for specific products.

Specifikacija merilnih naprav in metod za merjenje radijskih motenj in odpornosti - 2-3. del: Metode za merjenje radijskih motenj in odpornosti - Merjenje sevanih motenj

Ta del standarda CISPR 16 določa načine merjenja radiofrekvenčnih motenj v frekvenčnem območju od 9 kHz do 18 GHz. Vidiki merilne negotovosti so določeni v standardih CISPR 16-4-1 in CISPR 16-4-2.
OPOMBA: V skladu z vodilom IEC 107 [13]1 je standard CISPR 16-2-3 osnovna objava o elektromagnetni združljivosti, ki jo uporabljajo tehnični odbori v okviru Mednarodne elektrotehniške komisije (IEC). Kot je navedeno v vodilu 107, so za ugotavljanje uporabe standarda o elektromagnetni združljivosti odgovorni tehnični odbori. Odbor CISPR in njegovi pododbori so pripravljeni sodelovati s tehničnimi odbori pri vrednotenju posameznih preskusov elektromagnetne združljivosti za ustrezne izdelke.
