The Tektronix TCPA300 is an Oscilloscope Current Probe Amplifier, designed to extend the current measurement capabilities of oscilloscopes by providing the necessary power, signal conditioning, and scaling for a range of Tektronix TCP series current probes. It features automatic probe recognition, autozero and demagnetize functions, and a clear alphanumeric display for status and control.
