Abstract
A small, portable signal generator provides a unique marker signal modulated with a selectable number of degrees of freedom for insertion into a portion of a broadband communication system (BCS) such as a subscriber installation site that may or may not be connected to the remainder of the BCS. If payload signals are not present or brief interference with payload signals is tolerable, a high level marker signal may be injected with level control upon detection of an egress signal to detect very minor leakage sources and thus increase quality of the qualification of installation or repairs. If payload signals are present, marker signals are held to non-interfering levels and frequencies. Authentication of a signal received through an antenna is expedited and increased in confidence level by synchronization of the marker signal modulation pattern and the signal detector in a receiver.
