Shielded anechoic chamber

Listing ID #4063309

FEATURES:

A total low cost solution of Shielded Anechoic Chamber for antenna measurements and RCS measurement.

• A PAN type design for high performance shielded chamber, a Total Steel Structure (TSS), an improved design over conventional sandwich type wood core structure (WCS).
• TSS offers years of maintenance free, high RF attenuation.
• Easy expandability and relocation using less parts.
• P.U. Foam based pyramidal/wedge/walk –on/corner absorbers as required.
• Access Panel: Providing access to outer and inner signal. Consists of various RF connectors with matched terminations on both ends.
• Provided power line filter one phase, 2 lines, 15 Amperes, 220V.
• Various accessories and components available to utilize chamber in best possible way for various tests

• Frequency Range: 800MHz – 18GHz and beyond.
• Shielding Effectiveness (SE): Min.-80 dB on walls and -80 dB on windows or door. SE tested as per IEEE STD, 299.
• Quiet-Zone size: 0.5m X 0.5m Cross section. Length of quiet zone can be customized.
• Quietness Level: Min -30 dB at 800MHz raising to -40 dB at 3.0 GHz and higher frequencies.
