Status of standards for alternative test sites

The latest status of alternative test sites for radiated emission is to be discussed, for emission measurements mainly the existing and well proven standards EN 50147-2, CISPR 16, ANSI C63.4 2001 and VCCI. Testing is performed at present mainly in the frequency range from 30...1000 MHz. The above mentioned standards describe the qualification of alternative test sites over a metallic surface called a ground plane. In the last 5 years there have been many proposals for draft standards for fully anechoic rooms FAR in Europe. The FDIS for validation of fully anechoic rooms already is integrated in CISPR 16-1-4. The measurement procedure will be described and first experience and results will be discussed. The status of the frequency range extension in CISPR from 1 GHz up to 18 GHz will be discussed, and the new CISPR/A/602/CDV will be shown
