Teledyne LeCroy expands its portfolio of current measurement solutions with the new CP1000 current probe. The AC/DC current probe has been specifically designed for precise measurement of high currents in applications such as traction inverters, motor drives, fast charging stations, energy storage systems, and industrial power electronics. With measurement capability up to 1000 A RMS and 1400 A peak current, the CP1000 sets new standards for characterising modern high-power systems.
As the first oscilloscope manufacturer to offer a current probe combining 1000A continuous current capability with 1.5MHz bandwidth, Teledyne LeCroy fills the gap between traditional high-current transformers and high-bandwidth laboratory current probes. The CP1000 enables precise measurements in modern power applications.
The outstanding feature of the new current probe is its ability to measure continuous currents up to 1000 A with a bandwidth from DC to 1.5MHz. This allows developers to analyse not only total current but also fast switching events, current spikes, and high-frequency harmonics with exceptional accuracy. This capability is particularly important for SiC- and GaN-based power circuits as well as for efficiency and power-loss measurements.
Unlike many available high-current measurement solutions whose bandwidth is often limited to a few kilohertz, the CP1000 delivers the performance required to analyse modern fast-switching events. The higher bandwidth enables realistic capture of current rise times, contributing to more accurate determination of switching losses and overall efficiency.
The CP1000 features a generous 33mm core opening, enabling measurements on large conductors and busbars without interrupting the circuit. A 6-meter cable also provides greater flexibility and safety when testing high-voltage and high-current systems.
Thanks to direct integration via Teledyne LeCroy’s proven ProBus interface, the probe is automatically recognised and scaled. Functions such as Auto-Zero and Degauss can be conveniently controlled directly from the oscilloscope, accelerating test setup and improving measurement accuracy.
With the CP1000, development engineers gain a powerful solution for the reliable analysis of highly dynamic current waveforms in electric vehicles, motor drives, inverters, and other high-power electrical systems – from development and validation through to efficiency optimisation.
