The TBST-120/60/60/2 shielded tent has been designed with two layers of conductive fabric, suspended on rigid aluminum supports, the double-layer design significantly improving the tent’s shielding effectiveness. A filter panel mounted at the side provides one 240-V/10-A AC filter, two 240-V/10-A DC filters, and four coaxial feedthrough adapters with screw caps. The front opening provides access to the test space and is closed using conductive hook-and-loop tape in order to avoid compromising the shielding efficacy.

When measuring the conducted noise spectrum of a powered device being tested in an unshielded setup, conducted noise to be measured is often hidden below the ambient noise level, making accurate measurements impossible without eliminating the interference. Most shielded environments have previously been prohibitively expensive for many situations, but the TekBox shielded solution is now available at under $2,000.

Outer dimensions are 47.25 x 24 x 24 inch with an opening measuring 33.5 x 13.8 inches. The frame consists of 0.8 x 0.8-inch extruded aluminum supports. Applications include wireless device testing, EMC precompliance testing, secure communications, satellite communications, medical equipment shielding, and operator safety.

This high-attenuation enclosure, created by EMI company TekBox, is available now from distributor Saelig.
