Level error inherent of externally leveled microwave sources due to leveling loop components

A mathematical model of an externally leveled microwave generator system is presented with the aim to provide an insight into the distribution of energy throughout the leveling network and to show how system performance can vary based upon equipment parameters. The algorithm that was introduced during the application of Mason´s rule has always been helpful to the author. Searching for non-touching sets of loops tends to be tedious and prone to error and omissions. The use of loop set matrices as described provides a quick and systematic means of ensuring that each touching and non-touching loop set is identified
