The TDK 10 meter test range semi-anechoic RF chamber is designed to perform radiated emissions measurements at 10 meter distance in full compliance with ANSI C63.4, EN 50147-2, and CISPR 22 standards.
TDK hybrid technology absorber lining in this 10m EMC anechoic chamber achieves exceptional electrical performance with dimensions of only 18.0 m long x 12.0 m wide x 8.4 m high (59' x 39'-4" x 27'-6").
The RF anechoic chamber is lined with TDK ferrite tiles and IP-090 series hollow-taper, wedge-shaped, fully-matched absorbers to cover the frequency range from 30 MHz to 40 GHz. White end caps complete the EMC absorbers and greatly improve the illumination levels inside the EMC chamber.
NSA deviation is guaranteed to be within ±3.5 dB for a test volume of 3 m Ø, 2.5 m high.
By positioning TDK ferrite tile floor panels and IP-045C absorbers between the transmit antenna and EUT (Equipment Under Test), the RF semi-anechoic chamber can be used to perform radiated immunity measurements in full compliance with IEC 1000-4-3 standard in the frequency range from 26 MHz to 18 GHz. The field uniformity is guaranteed over 75% of the surface (12 of the 16 points) of a vertical plane of 1.5 m x 1.5 m high, 0.8 m from the ground.
