It details the placement of transmitting and receiving antennas to ensure the enclosure meets specific decibel (dB) attenuation requirements.

The procedure involves measuring the signal level transmitted through the shield over a frequency range (typically 10 kHz to 40 GHz) and calculating the difference from a reference calibration. en 50147-1 pdf

The transmitting antenna and receiving antenna are placed in open space, separated by a fixed distance (typically 1 to 3 meters). A known RF power level is generated. The received signal strength ( Vrefcap V sub r e f end-sub ) is recorded across all target frequencies. Step 2: The Enclosure Measurement
