In order to determine the maximum number of adjustments needed to obtain any given tolerance for reflections, one must make use of the fact that the reflection coefficient at a junction between an isolator and a reciprocal line is the same when measured from either side of the junction. This fact is true for any reciprocal device. In order to prove this for an isolator, a thermodynamical argument is offered.
