摘要: An AC impedance measurement system is used for measuring the impedance of a DUT. A measured voltage is applied to a first DUT terminal by a first digital to analog converter, the voltage appearing at the second terminal of the DUT is monitored through an analog to digital converter and forced by a second digital to analog converter to a desired negligible value, and a digital controller determines the impedance of the DUT from the measured voltage and the current necessary to force the voltage appearing at the second terminal to the desired negligible value.

摘要: A range-changing circuit for a measurement device having a desirable range includes an array of graduated impedances. And amplifier supplies an electrical voltage to at least one of the impedances of the array. A voltage sensing and limiting switch is provided in a feedback path of the amplifier. The switch limits said electrical voltage supplied to said at least one of the impedances in response to a sensed voltage that is sensed by the switch. An electrical voltage in the desirable range is developed across a different one of the impedances of the array based on an operation of the switch.
