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.

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.

摘要： A spatial transformer includes an insulating substrate; a plurality of test terminal assemblies on the substrate; and a plurality of contact surfaces on the transformer, each providing an interconnection point for electrical connection between a respective test terminal assembly and a device under test. Each test terminal assembly has a center conductor trace on an upper substrate surface; a lower substrate guard trace beneath the center conductor trace; and a pair of upper substrate guard traces adjacent to opposite sides of the center conductor trace, the guard traces being electrically interconnected. The guard traces in combination with the center conductor trace provide a desired characteristic impedance for an RF signal applied therebetween or a guarded DC connection for a DC signal applied to the center conductor trace and a DC guard applied to the guard traces.

摘要： A reed relay is provided with two shields. The shields are fabricated from copper foil and insulated from each other by polyester tape or film. One shield is connected to one lead of a switching element and the other shield is connected to another lead of a switching element. The shields are wrapped around the switching element in an overlapping manner. The dual shield configuration reduces leakage and interference to improve performance, particularly in low current applications.

摘要： Apparatus is provided for continuously compensating for the dielectric absorption effect in a measuring capacitor in a circuit which employs means for charging the capacitor to develop an output signal thereacross and wherein the absorption effect causes an error in the output signal following a charging interval. The dielectric absorption effect is represented by at least one impedance branch connected in parallel with the capacitor and this branch includes a resistor and a capacitor connected together in series and having a RC time constant. Compensating means is provided having a correction means associated with the impedance branch and wherein the correction means continuously receives the output signal and provides therefrom a compensating signal. The correction means has a time constant that corresponds with that of the associated impedance branch. The compensating signal is combined with the output signal to provide a compensated output signal.
