TEKBOX The TBST-86/49/45/1-B from TEKBOX is a Shielded Tent that is designed to suppress interference from ambient noise in EMC pre-compliance measurements. It has two layers of conductive fabrics and is supported by rigid aluminum profiles that measure 20 x 20 mm. This shielded tent provides an ambient noise attenuation of more than 50 dB (from 4.5 to 6 GHz). It measures 86 x 48 x 48 mm and weighs 10.8 Kg. The filter panel, equipped with a 240V/10A mains AC filter (optional for the smaller tent), two general-purpose 240V/10A AC/DC filters, and four coaxial feed-through adapters, enhances its functionality.
