Teledyne LeCroy CP031 30 Amps, 100 MHz BW Current Probe

The Teledyne LeCroy CP031 is a 30 A AC/DC current probe delivering 100 MHz bandwidth for precision current measurement across DC, AC, and impulse waveforms. Built on Hall effect and transformer technology, it clamps non-intrusively around conductors up to 5 mm diameter without circuit interruption. The probe connects via ProBus active interface to compatible Teledyne LeCroy oscilloscopes, enabling automatic scaling, direct Amp display, and integrated Autozero and Degauss functions controlled from the scope’s user interface. Rise time of ≤3.5 ns supports fast transient capture, while 300 V maximum input voltage accommodates high-voltage measurement scenarios.
