1. A method, comprising:
coupling an electrical cable, comprising multiple wires, to circuitry having a configuration comprising a resistor bank connected to the wires and a gain amplifier including a feedback resistor, the resistor bank including a first plurality of resistors and a second plurality of resistors, the second plurality of resistors being coupled to the gain amplifier, each of the first plurality of resistors having a progressively increasing resistance, each of the second plurality of resistors having a progressively increasing resistance different than the progressively increasing resistance of the first plurality of resistors, wherein each wire is coupled between a resistor in the first plurality of resistors and a corresponding resistor in the second plurality of resistors; measuring a gain of the circuitry and the cable; identifying that one or more of the wires in the cable is defective based on the measured gain being different than an expected gain, the expected gain being determined from the circuitry configuration and a non-defective cable; and outputting an indication that one or more of the wires is defective. |
