Description

Compared with other test methods, SMART^TM chambers offer the advantages of lower cost, higher field-to-input power ratios, and the ability to accept large test systems.

SMART^TM chambers operate by using their interior surfaces to reflect internally radiated RF fields. One or more rotating paddles, or tuners, are used to change the cavity boundary conditions. This creates fields having statistical isotropy and field homogeneity over a large working volume. ETS-Lindgren's patent pending tuner design ensures fast settling times and maximum through put during mode tuning tests. Due to recent advances in reverb statistical theory, the field measured at one point can be used to predict the maximum field at any other position.

The reverberation chamber has intrinsic properties of isotropy and homogeneity that provide several unique features for testing. Assuming proper configuration and a given uncertainty level; field measurement results will be the same regardless of where in the room they are taken; reconfiguration of the EUT will have minimal effect on those measurements; EUT measurements made between one or more chambers will be the same. The benefits are high measurement repeatability and test result reproducibility.

Adding to the appeal of reverberation chambers is that robust field strengths can be generated using less power than required by other test environments. The benefit is that less expensive amplifiers can be used without sacrificing performance. SMART^TM chambers are well suited to simulate the complex EMC of cavities, such as computer rooms, medical equipment rooms, aircraft avionics bays, and vehicle engine compartments. A SMART^TM chamber simulates all wave polarizations and incidence angles during a full test.

ETS-Lindgren understands reverberation chamber technology, and can design a chamber to meet your exact needs. We can work with you to determine the correct chamber volume for achieving frequency range, select interior finishes to optimize mode density and Q-bandwidth, and recommend the right antenna and amplifier combination for field strength requirements.
