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
TESEQ reverberation chambers can be used in a range of applications, including:
  • 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)
The generously proportioned TESEQ XS (2700 L x 1500 D x1300 H mms) and TESEQ 2XS (1500 L x 800 D x 1000 H mms) provide LUF parameters of 500 MHz and 800 MHz respectively. Both chamber also have an upper frequency of 18 GHz, making them suitable for automotive, commercial, and military applications.

These reverberation chambers are provided with dual feed-through ports, stirrer with control program, and filtering.
