  • Patent number: 10488437
    Abstract: A tester is described having output circuits that are operable in either power mode or driver mode. A switching circuit connects force and sense lines to one of the output circuits when in power mode, or connects the same lines separately to the output circuits when in driver mode. A further configuration allows for power to be provided through the lines separately while detecting a measure of power through each line and correcting for unknown resistances of leads connected to the lines.
