Patent ID: 6987392

Claim:
A method of testing the RF-shielding effectiveness of an RF-shielding enclosure for electronic equipment enclosed therein comprising the steps of: (a) deploying said RF-shielding enclosure containing said electronic equipment to an installation field site containing other electronic equipment; (b) transmitting RF energy from an RF transmitter enclosed within said RF-shielding enclosure; (c) measuring RF energy received at an RF receiver external to said RF-shielding enclosure; (d) providing an indication of the effectiveness of said RF shielding to block the transmission therethrough of said RF energy transmitted by said enclosed RF transmitter; (e) coupling power through a power line containing a power supply filter to said electronic equipment installed within said RF-shielding enclosure; (f) coupling RF energy from said RF transmitter enclosed within said RF-shielding enclosure to a location of said power line inside said enclosure; (g) coupling said RF receiver to a location of said power line outside said enclosure; (h) measuring RF energy coupled to said power line by said RF transmitter in step (f) and received by said RF receiver; and (i) providing an indication of the effectiveness of said power supply filter to block the transmission therethrough of said RF energy coupled to said power line in step (f).
