Anechoic Chamber for 3m testing onTelecommunication & ITE applications
This 3m Semi-Anechoic Chamber has been provided to the major Chinese supplier of ITE equipment for full-compliance radiated emission measurements in 3m test distance and for radiated immunity testing in the 3m test distance. The facility covers the whole frequency range 26MHz to 40GHz in accordance with the latest editions of International, US and European standards for EMC testing and site validation. Listing of the 3m site as FCC facility, getting European accreditation or VCCI recognition are both possible.
Typical EUTs (Equipments Under Test) are telecom equipment as well as information technologies equipment (ITE).
The chamber’s modularity for RF shielding and RF absorber lining is a proven advantage should the chamber ever be relocated or expanded.
Dimensions: 8.80m x 5.80m x 5.55m (L x W x H)
Radiated Emission Measurements
30MHz to 1GHz: Full compliance with ANSI C63.4 and CISPR 16-1-4 in 3m measuring distance, ±3.5dB
1GHz to 18GHz: Full compliance in analogy to ANSI C63.4 (TL) in 3m measuring distance, ±3.0dB
Quiet Zone: 2m cylinder, height 2m, floor standing
Radiated Immunity Tests
The chamber is fitted with a 1.5m large single leaf door and a 0.9m large personnel door; a 2m diameter turntable, an antenna mast and controller and additional shielded rooms, for the power amplifiers and a test equipment control room, were installed. Over the air measurements on mobile phones, can be carried out by using a specific positioning device, which has been provided by Albatross Projects.
Other customized solutions to suit the customer’s test and measurement needs were provided. These included a RF shielded CCTV camera systems, audio intercom, smoke detection, fiber optic converters, RFI power line and signal line filters, RF absorber lining with 12” and 18” matched hybrid RF absorbers with light reflective white caps.
