The Teledyne LeCroy CP031A is a high-sensitivity current probe engineered for precise AC and DC current measurement up to 30A across a 100 MHz bandwidth. Designed for power electronics, low-power circuit analysis, and detailed device characterization, this probe delivers 10 mV/A sensitivity on the 5A range and 3.33 mV/A on the 30A range, with DC accuracy of ±1% of reading and phase accuracy of ±1° @ 100 kHz. The probe supports a maximum common mode voltage of 600 VRMS CAT III, exhibits noise below 2.5 mA RMS, and achieves response times under 3.5 ns with slew rates exceeding 10 A/µs. Integration with Teledyne LeCroy oscilloscopes via the probe interface enables automatic scaling and de-skewing for streamlined measurements in development and test environments.
