Receiver Canonic Models.
Abstract
The concept of an equivalent receiver is introduced. This receiver consists of a parallel combination of a unit-gain amplifier and a third order transfer function, with the parallel combination followed successively by a linear filter, and an ideal frequency translator. The general principles of phase-coherent measurement of this cascade are presented, including the sources of, and effects of, residual phase errors. The conceptual methods for eliminating these residual errors are also presented. It is shown, in block diagram form, how to implement the measurement principles and detailed schedmatics are given for one of the two coherent measurements. The results of experiments with this test set are presented and it is concluded that this phase-coherent test set is highly workable. A supplementary section presents information on the theoretical statistics of line-of-sight interferers. (Author)
