Measuring AC and DC Currents
LeCroy current probes do not require the breaking of a circuit or the insertion of a shunt to make accurate and reliable current measurements. Based on a combination of Hall effect and
transformer technology, LeCroy current probes are ideal for making accurate AC, DC, and impulse current measurements.
Fully Integrated with Oscilloscope
Many current probes require external power supplies or amplifiers to display a waveform on the oscilloscope screen. All 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 full integration also allows for Degauss and Autozero functions to be done
directly from the oscilloscope with a single button press.
Applications
LeCroy current probes are available in a wide range of models for a wide range of applications. The full range of LeCroy current probes includes models with bandwidths up to 100 MHz,
peak currents up to 700 A and sensitivities to 10 mA/div. Multiple current probes can be used together to make measurements on three-phase systems, or a single current probe can be used
with a voltage probe to make accurate instantaneous power measurements. LeCroy current probes are often used in applications such as the design and test of switching power supplies,
motor drives, electric vehicles, and uninterruptible power supplies

The DCS015 calibration source has both voltage and current time-aligned signals, which enables the precise deskew
of voltage and current probes. Most voltage probes along with the CP031, CP030 and AP015 are compatible with the DCS015.
