Abstract
An instrument to test electronic components, the instrument including a drive unit electrically connecting the component and electrically driving the component to generate a field in the nearby space. The instrument also includes a test device electrically insulated from the component and mounted in its vicinity in order to measure the field generated by the component. The drive unit is designed to apply a voltage to the component. The test device includes an instrument amplifier measuring the voltage differential of two electrodes positioned at two sites in the electric field generated by the component. One of the electrodes is positioned near the component.
