Now available from Westek Electronics , TESEQ reverberation chambers are a cost effective and uncomplicated solution to EMC compatibility testing.
The new TESEQ model XS and 2XS reverberation chambers provide a realistic alternative to the use of open area test sites (OATS) and anechoic chambers. They provide a modern method for EMC compatibility testing for emission and immunity, and are also an alternative to GTEM cells.
The reverberation chamber features a stirring paddle and represents a multi-mode resonator. The stirrer changes the natural resonant frequencies in such a way that a time-averaged, spatially homogeneous field distribution is achieved.
A particular challenge, however, is the achievement of obtaining suitably homogeneous fields at lower frequencies; the LUF (lowest usable frequency) parameter.
EMC testing using TESEQ reverberation chambers has several advantages over established methods, including:
- efficient power conversion with small amplifiers for cost efficiency
- no need for absorbers meaning cost and space efficiency, along with better fire prevention
- large test volume
- random field coming from all directions in any orientation and polarization, meaning no need for turntable or mast
- IEC 61000-4-21
- screening effectiveness, power spectral density measurements of WLAN, bluetooth, mobile phone
- airborne equipment, RTCA DO 160 F (>100 MHz)
- MIL461e, alternative test procedures (200 MHz-40 GHz)
- automotive, SAE J1113/27, GMW 3100GS, GM9114P, ES-XW7T-1A278-AC (>400 MHz)
These reverberation chambers are provided with dual feed-through ports, stirrer with control program, and filtering.
