By counting the number of pass/fail occurrences of a DUT (Device under Test) in the stirring process in a reverberation chamber (RC), the threshold electric field (E-field) level can be well estimated without tuning the input power and repeating the whole testing many times.

A Realisation of Channel Emulation in a Reverberation Chamber method for Over-the-Air Compliance Testing in Support of 3GPP Standardisation
