En 50147-1 Pdf [exclusive] May 2026
EN 50147-1:1996 defines methods for measuring the shielding effectiveness of anechoic chambers against electromagnetic interference from 9 kHz to 40 GHz. The standard outlines procedures for testing magnetic fields, electric fields, and plane waves, requiring the calculation of attenuation in decibels, though it has largely been superseded by IEEE 299. Official copies of the technical standard are available through national standards bodies such as BSI, DIN, or AFNOR.

Remember: a chamber that fails EN 50147-1 validation is a liability, not an asset. It can produce false passes (due to external noise masking real emissions) or false failures (due to ambient signals entering during immunity tests). By mastering this standard, you protect the integrity of every EMC measurement you will ever make.
Key Terminology
- Shielding Attenuation (a): The ratio of the field strength received without the shield (e.g., in open space or a reference environment) to the field strength received with the shield in place, expressed in decibels (dB).
- Reference Antenna: An antenna placed outside the chamber during reference measurement.
- Measurement Antenna: An antenna placed inside the chamber during shielded measurement.
- Dynamic Range: The maximum measurable attenuation, limited by the leakage of the system and the sensitivity of the receiver.
