Maximum rates of frequency scanning and mechanical or electronic stirring for distortionless signal generation inside electromagnetic reverberation chambers

We present upper bounds for the rates of frequency scanning and mechanical or electronic stirring inside a reverberation chamber. The bounds are obtained by imposing quasi-stationarity of the field to hold, allowing avoidance of nonlinear distortion of the analog or digital excitation (test) signal injected into the chamber. The interior field is represented as a dynamic stochastic process causing random hybrid modulation of the excitation field.
