The Teledyne LeCroy CP150B is an AC/DC current probe engineered for precision measurement of currents to 150 Arms continuous and 300 A peak. Operating at 10 MHz bandwidth with 35 ns rise time, it combines Hall effect and transformer technology to capture DC, AC, and impulse currents across power electronics, motor drive, and electric vehicle applications.
The probe connects via ProBus interface directly to compatible Teledyne LeCroy oscilloscopes, eliminating the need for external power or circuit interruption. ProBus integration enables automatic waveform scaling in Amps, real-time power calculation in Watts, and direct access to degauss and autozero functions from the oscilloscope interface. The 1 MΩ input termination is activated automatically through the ProBus connection.
