Scope

There are many different test sites and facilities that have been constructed to make radiated emission measurements at frequencies above 30 MHz according to CISPR 16-1. Most are protected from the weather and the adverse effects of the radio frequency ambient noise. These include all weather covered open area test sites and absorber lined shielded enclosures. Whenever construction material encloses a test site, there exists the possibility that the result of a single normalized site attenuation measurement as specified in subclause 16.6 of CISPR 16-1 is not adequate to show such alternate site suitability NOTE: Radiated emission sources located near dielectric interfaces have been shown to have variations in current distribution that can affect the radiated properties of the source at that location. When the EUT can be located near these interfaces, additional site attenuation measurements are required. This standard specifies requirements for alterneative test sites regarding site attenuation. As long as the document CISPR/A(CO)63 is not published as part of CISPR 16, this standard shall be used for test site qualification.
