Abstract	The energy distribution among the modes in an over-moded reverberation chamber operating at a particular frequency is studied for varying tuner speeds. The understanding of this spread is important in quantifying upsets of equipment in the chamber. The spectral characterization of a time varying electromagnetic field is done using the averaged periodogram approach. The complex insertion loss $S_{21}$ is the measured quantity and an estimation of the power insertion loss that will be used in the determination of Q factor, is obtained from the sampling data for varying angular positions of the tuner. The same procedure is followed for varying tuner speeds and the Q is reported. The autocovariance for this random process can be found by taking a Fourier transform of the spectral density function. The autocovariance function helps in determining the number of independent samples of the field. The field experienced by a EUT in the usable volume due to continuous rotation of the tuner is analyzed.
