Teledyne LeCroy CP150 Current Probe 150 A, 10 MHz

The Teledyne LeCroy CP150 is an AC/DC current probe engineered for non-invasive measurements up to 150 A RMS continuous current, with peak capability to 500 A. Operating across a 10 MHz bandwidth, it combines Hall-effect and transformer technology to capture DC, AC, and impulse currents without circuit interruption or shunt insertion. The probe connects via Teledyne LeCroy ProBus, delivering onboard power and enabling automatic waveform scaling in Amperes and calculated power traces in Watts directly to compatible oscilloscopes. Degauss and Autozero functions are controlled from the scope interface, eliminating external calibration steps.
