Maximum Rate of Frequency Scanning for Distortionless Signal Generation in Electromagnetic Reverberation Chambers

We derive theoretical and experimental performance based upper bounds for the rate of frequency scanning (sweeping) or electronic stirring inside a reverberation chamber. The interior field is modeled as a dynamic process of frequency modulation of the source field. The bounds are obtained by imposing quasi-stationarity of the field, as a requirement for preventing nonlinear distortion of an analog or digital excitation (test) signal injected into the chamber.
