Understanding Reverberation Chambers

The frequency of operation of electronic devices and wireless communications is steadily increasing into the GHz range. Whilst a range of EMC measurement techniques exist for use above 1 GHz, alternative measurement techniques can be used for these higher frequencies.

The reverberation chamber is one such technique. It offers the capability to perform emissions and immunity measurements from a few hundred MHz upwards with a larger working volume than possible in conventional anechoic chambers and absorber lining is not required.

High field strengths are achievable with lower power requirements than conventional anechoic chambers. The reverberation chamber illuminates a test object with equal energy from all directions and with all polarisations, ensuring that a thorough immunity test is performed.

For emissions measurements the reverberation chamber measures total radiated power. This avoids the need to determine the direction of maximum emissions which becomes increasingly difficult at frequencies above 1 GHz due to the possible high directivity of test objects.

This one day course provides an introduction to the reverberation chamber as a measurement environment, and discusses the operation and underlying physics involved.

Course attendees can expect to learn how the chamber works and how and when it is advantageous to apply a reverberation chamber over a traditional semi or fully anechoic.
