Patent ID: 10509063

Abstract:
Systems and methods provide measurement of one or more electrical parameters (e.g., impedance) of a device under test (DUT) using an electrical parameter measurement device (e.g., multimeter, oscilloscope) that includes reference signal circuitry that generates, detects, and processes common mode reference signals. A measurement device may include a known common mode AC reference voltage source coupled to a common input terminal. During measurement of a DUT, circuitry may detect a signal at a voltage test input terminal and a signal at the common input terminal. The circuitry may process the first and second signals to determine one or more electrical parameters of the DUT, which one or more electrical parameters may be used to implement one or more features. The determined electrical parameters may be presented to an operator via a visual indicator device and/or may be communicated to an external device via a wired and/or wireless communications interface.
