We don’t need no stinkin’ RF-free room

By Bill Schweber -- EDN, 9/27/2005

“Personal” is the descriptive adjective for many devices, so why not a personal RF-test enclosure? If you have no access to or can’t afford the preliminary sessions in a standard RF-screened room, consider a benchtop RF-test enclosure from Saelig Co. The unit’s internal dimensions are 8 in. high, 17 in. wide, and 10.5 in. deep; it has ultrafine-shielded-mesh gloves in the access holes.

An RF-filtered supply powers internal illumination from low-voltage incandescent bulbs, letting users see through the RF-tight window and manipulate a product inside. The box comes with user-specified RF connectors for input and output. RF-absorbent foam with 24-dB attenuation lines the interior, and the double-sealed access-door lip has 90 dB of isolation. The STE3000B sells for $1095, approximately the price of a day’s use of a commercial RF-screened room.
