The Rigol RP1003C is a clamp-on current probe that delivers DC to 50 MHz bandwidth for simultaneous AC and DC current measurement. Using a thin film Hall effect sensor element, it captures peak currents to 50A with continuous operation at 30A RMS, providing 0.1 V/A gain at 1MΩ input impedance and rise time of ≤7 ns. The split-core design accommodates conductors up to 5 mm diameter, enabling non-invasive measurements on live circuits without breaking connections. Gain accuracy reaches ±1.0% reading ±1 mV for currents to 30A, with ±2.0% accuracy for peak transients from 30A to 50A. The probe connects directly to oscilloscope BNC inputs and includes AC/DC coupling selection for flexible signal conditioning. CAT II 600 V / CAT III 300 V safety ratings support industrial and laboratory environments.
