Abstract:
A device and method for measuring an impedance between first and second nodes in an electrical circuit without removing components includes at least one current source to provide first and second currents or current signals of known values. First and second probes contact the respective first and second nodes to apply the first and second currents. A third common probe contacts the circuit at a common node that experiences the same current flow as between the first and second nodes. At least one voltage meter measures voltages corresponding to the first and second currents. A processor calculates the impedance based on the known values of the currents, and the measured values of the voltages.
