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 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.
NOTE In accordance with IEC Guide 107, CISPR 16-1-4 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 sub-committees are prepared to cooperate with product committees in the evaluation of
the value of particular EMC tests for specific products.
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, further information on radio disturbance is
given in Part 3, and uncertainties, statistics and limit modelling are covered in Part 4 of
CISPR 16.

Specifikacija merilnih naprav in metod za merjenje radiofrekvenčnih motenj in odpornosti - 1-4. del: Merilne naprave za merjenje radiofrekvenčnih motenj in odpornosti - Antene in preskuševališča za meritve sevanih motenj

Ta del standarda CISPR 16 določa značilnosti in učinkovitost opreme za meritve sevanih motenj v frekvenčnem območju od 9 kHz do 18 GHz. Vključene so specifikacije za antene in preskuševališča.
OPOMBA: V skladu z vodilom IEC 107 je standard CISPR 16-1-4 osnovna objava o elektromagnetni združljivosti, ki jo uporabljajo tehnični odbori v okviru Mednarodne elektrotehniške komisije (IEC). Kot je navedeno v vodilu IEC 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.
Zahteve v tej publikaciji se uporabljajo za vse frekvence ter za vse ravni sevanih motenj v opredeljenem območju CISPR merilne opreme.
Merilne metode so zajete v delu 2–3, dodatne informacije o radijskih motnjah so navedene v 3. delu, negotovosti, statistike in modeliranje z omejitvami pa so zajete v 4. delu standarda CISPR 16.
