Radio Frequency Anechoic Chamber Facility

Metadata Updated: March 8, 2017

FUNCTION: Supports the design, manufacture, and test of antenna systems. The facility is also used as an electromagnetic compatibility/radio frequency interference (EMC/RFI) test chamber.DESCRIPTION: The facility consists of a shielded 31 x 31 x 120 ft tapered anechoic chamber and secondary shielded 12 x 20 x 10 ft rectangular anechoic chamber, both with computer-controlled automated antenna measurement systems and machine shop tool/assembly area. The tapered chamber is pyramidal in shape and transitions to a circular conical section at the transmitting end. The back wall of the chamber is covered with 169 absorbing pyramids that are 9 ft in length. The sides, ceiling, and floor in the quiet zone area are lined with 4-ft absorbing pyramids, and the taper is covered with 2-ft wedge absorber. In the center of the floor is a 9-ft-diameter pit that contains the large model tower. Also in the pit are two scissor lifts that move a section of the floor, allowing the tower to be lowered for mounting models and antennas at ground level.INSTRUMENTATION: The chamber is controlled by an Agilent PNA-based Orbit FR-959 Measurement System, allowing direct measurements from 100 MHz to 6 GHz, remote-mixed measurements from 2 to 18 GHz, and measurements to 110 GHz with appropriate additional mixers. A dualport high-speed transmit multiplexer allows single- or dual-polarized measurements to be made very quickly, and a high-speed 8-port receive multiplexer allows multiple antennas or antenna configurations to be measured in the same cut.
