Computer controlled alternating-current bridge-type impedance measure-ment system for electrical circuit components
First Claim
1. IN A SYSTEM FOR MEASURING THE IMPEDANCE OF ELECTRICAL CIRCUIT COMPONENTS HAVING UNKNOWN INDUCTIVE AND CAPACITIVE REACTANCE CHARACTERISTICS, THE COMBINATION OF, MEANS FOR SELECTIVELY CONNECTING EACH ONE OF A PLURALITY OF STANDARD RESISTANCE ELEMENTS IN SERIES WITH ONE OF SAID COMPONENTS AS THE SERIES BRANCHES OF A FIRST ARM OF AN ELECTRICAL BRIDGE CIRCUIT, MEANS FOR CONNECTING AN ENERGIZING ALTERNATING-CURRENT SIGNAL SOURCE WITH SAID BRIDGE CIRCUIT IN PARALLEL RELATION WITH SAID FIRST ARM THEREOF, MEANS PROVIDING TWO RESISTIVE AND SUBSTANTIALLY NON-REACTIVE VOLTAGE-DIVIDER ARMS CONNECTED IN PARALLEL RELATION WITH THE FIRST ARM TO RECEIVE ALTERNATING-CURRENT SIGNALS THEREWITH FROM THE SAME SOURCE, EACH OF SAID VOLTAGE-DIVIDER ARMS HAVING AN OUTPUT TERMINAL CONNECTED THEREON BETWEEN THE ENDS THEREOF, MEANS PROVIDING CONDUCTIVE WIRING AND COMPONENT SHIELDS FOR SAID SYSTEM, ONE OF SAID
