This Technical Report applies to emission measurements of radiated electromagnetic fields in Fully
Anechoic Rooms (FAR) in the frequency range from 30 MHz to 18 GHz. This Technical Report covers the
frequency range from 30 MHz – 1 000 MHz. The frequency range above 1 GHz is under consideration,
due to the absence of practical experience.
This Technical Report describes the validation procedure for the Fully Anechoic Room for radiated
emission tests and the procedures to carry out the tests (e.g. test set up, EUT position, cable layout and
termination, test procedures). Recommendations for the relation between FAR emission limits and
common Open Area Test Site (OATS) emission limits given in standards such as EN 55011 and
EN 55022 are given in Annex B.
This FAR emission method may be chosen by product committees as an alternative method to emission
measurement on an Open Area Test Site (OATS) as described in CISPR 16 series. In such cases, the
product committee should also define the appropriate limits. Typical measurement uncertainty values for
FARs and OATS are given in Annex C.
