ABSTRACT:
A measurement system with selectable feedback paths includes a DUT interface including a first and a second DUT sensor, the first sensor being connected to a first feedback path for providing a measure of a first DUT characteristic, the second sensor being connected to a second feedback path for providing a measure of a second DUT characteristic, the sensors having a shared reference path and each feedback path including a set point adjustment; a differential amplifier system including differential inputs and differential outputs, the differential outputs being applied to the DUT interface; and a multi-pole switcher for connecting the differential inputs to either the first feedback path and the reference path or to the reference path and the second feedback path, respectfully. The first feedback path is selected to produce a desired first DUT characteristic or the second feedback path is selected to produce a second desired DUT characteristic.
