Abstract : An engineer, who is monitoring signals on oscilloscopes, can use one of a set of pushbuttons to select a specific channel for further monitoring on one or more other instruments. The switching network is controlled by a microprocessor and is designed to route any one of N (36) incoming analog signals to one of M (3) instrumentation inputs. The switching network is essentially M independent N-to-1 analog multiplexers comprising relays designed to function as a single system. The microprocessor insures that only one analog signal at a time can be selected for a single instrumentation channel while permitting a signal to be simultaneously used on any or all of the remaining instrumentation channels. A second contact on each relay provides a signal to tell if the selected relay is energized. Patents, Computers. (JES)
