En 50147-1 Pdf File
EN 50147-1 is a European standard, often available in PDF, defining procedures for measuring the shielding effectiveness of enclosures like anechoic chambers across a 9 kHz to 40 GHz range. It outlines magnetic, electric, and plane wave test methods to validate shielding integrity, typically performed before installing internal absorbent materials.

EN 50147-1 sets out several key requirements for electrical and electronic equipment, including: en 50147-1 pdf
Shielding Measurement: Placing the transmitter outside the chamber and the receiver inside (or vice versa) to see how much the signal is attenuated by the walls. EN 50147-1 is a European standard, often available
Antenna Placement: Precise distances and heights for measurement tools. Radiated emissions : Measurements are taken using a
- Radiated emissions: Measurements are taken using a spectrum analyzer and a measurement antenna.
- Conducted emissions: Measurements are taken using a line impedance stabilization network (LISN) and a measurement receiver.
- ESD testing: Equipment is subjected to ESD pulses using a ESD generator.
- RF immunity testing: Equipment is subjected to RF fields using an anechoic chamber or a stripline.
To perform a test compliant with EN 50147-1, specific hardware is necessary to maintain accuracy across the wide frequency spectrum. Signal Generators: Must cover the 9 kHz to 40 GHz range.
