ABSTRACT:
A method for determining the electromagnetic RF shielding effectiveness of a shielding enclosure including sequentially driving the four diagonally opposite corner pairs of the enclosure with a RF signal, measuring the RF energy leakage for each corner pair, and averaging the four measured RF leakage levels to obtain an average RF energy leakage level. This average RF energy leakage level may then be compared with prior (preferably immediately after manufacture) measured average RF energy leakage levels to obtain an indication of the RF energy shielding effectiveness lost, if any, during the time from the prior test to the current test.
