Teledyne LeCroy current probes make accurate and reliable AC, DC, and impulse current measurements without requiring the breaking of a circuit or the insertion of a shunt. This capability is based on a combination of Hall effect and transformer technology. Many current probes require external power supplies or amplifiers to display a waveform on the oscilloscope screen
LeCroy current probes are powered through the LeCroy ProBus® connection and require no additional hardware. Along with providing power, the ProBus connection allows the current probe and oscilloscope to communicate, resulting in current waveforms automatically displayed on screen in Amps, and calculated power traces scaled correctly in Watts. This integration also allows for Degauss and Autozero functions to be carried out directly from the oscilloscope with the press of a button. Applications of LeCroy current probes include use in the design and test of switching power supplies, motor drives, electric vehicles, and uninterruptible power supplies.
