As different areas within the chamber could yield variations in the field uniformity inside the quiet zone caused by reflections, it is important to characterize the electromagnetic fields with the reference antennas uniformly illuminating the anechoic chamber. However, in order to keep the spurious emissions quality of the quiet zone characterization manageable in terms of test time, the number of orientations for the spurious emissions quality of quiet zone validation is limited when compared to the number of orientations for the in-band quality of quiet zone validation.
