Reverberation Chamber Measurements

The reverberation chamber is a custom built measuring chamber that uses the walls and different reflectors to create different modes inside the chamber

During immunity test, the test object is exposed to electromagnetic fields from all directions simultaneously. During emission measurements, the total emission is measured from the unit (TRP = Tota

Purpose

The reverberation chamber has some advantages and disadvantages compared to traditional EMC measurements.

The benefits of immunity testing in a reverberation chamber are that lower power is needed to obtain high field strengths and that the test object is exposed to disturbance from all directions, which should be safer than if it is exposed from 4 directions. One disadvantage is that it takes longer to perform.

The advantages of emission measurements are that it is faster to measure TRP than to measure TRP in a fully anechoic chamber. The disadvantage is that it does not measure ERP and that the direction of the emission from the sample object cannot be measured.
