More Information
Summary:A power testing device includes a communication port with pins that receive signals from a device under test. First test circuitry is coupled to a first set of pairs of the pins, and second test circuitry is coupled to a second set of pairs of the pins. A switch is coupled to the first test circuitry and/or the second test circuitry. While the switch is in a first state, the first test circuitry and the second test circuitry are electrically isolated from each other. While the switch is in a second state, the first test circuitry and the second test circuitry are not electrically isolated from each other. A processor is coupled to the first test circuitry, the second test circuitry, and the switch. A memory stores instructions that cause the processor to control operation of the first test circuitry, the second test circuitry, and the switch.
