A high input impedance AC and DC active probe is required to increase the input resistance and sensitivity of such measuring instruments as oscilloscopes and multimeters. Presented here is one such solution that consists of a single operational amplifier (op-amp) and selectable gain. The active probe protects inputs of the test equipment during testing and […]
