: High-power immunity testing generates intense electromagnetic fields. The shield prevents these fields from radiating into the surrounding office and interfering with other equipment or exposing personnel to radiation. Core Measurement Principles

The standard provides detailed procedures for testing the effectiveness of the shielding, which include:

is the received power calibration level with no shield present. Pshieldedcap P sub s h i e l d e d end-sub To acquire an official, fully updated copy of

: It applies to measurements between 9 kHz and 40 GHz .

It evaluates the overall integrity of the shield, paying special attention to potential weak points like doors, honeycomb ventilation panels, power line filters, and structural seams. Core Technical Requirements and Methodology

The antennas are separated by the shielding wall. The transmitter feeds the signal from the outside while the receiver records the residual energy inside. The shield prevents these fields from radiating into

: Detailed lists of required test frequencies.

: Guidelines for calculating measurement errors.

It typically covers measurements from 9 kHz up to 40 GHz, depending on the specific operational requirements of the facility.

: To measure the transmitted signals with a narrow resolution bandwidth to maximize dynamic range.

All of these national versions are technically identical to the original CENELEC document.
