High sensitivity scope current probes measure down to 1 mA/div

April 17, 2015 // By Graham Prophet
Teledyne LeCroy’s CP030A and CP031A are high sensitivity current probes providing sensitivity down to 1 mA/div allowing users to measure current from the mA range up to a continuous current of 30 Arms and peak current of 50A, all with the same probe.

The probes provide a small form factor, with small jaws that can probe currents in tight spaces and still clamp onto conductors up to 5 mm in diameter. The CP030A and CP031A feature a bandwidth of 50 MHz and 100 MHz, respectively.

The CP030A and CP031A expand the capabilities of the LeCroy current probe family to a wider range of applications by providing the ability to measure and analyse low current waveforms. The sensitivity of 1 mA/div combined with 1% DC and low frequency accuracy allows for more precise and accurate low current measurements on LeCroy oscilloscopes. When used with HDO high definition oscilloscopes with HD4096 technology, users will obtain highly accurate, low current waveforms with 12-bit resolution for improved debug and analysis.

Many current probes require external power supplies or amplifiers to display a waveform on the oscilloscope screen. The CP030A and CP031A probes connect to the oscilloscope through the ProBus interface and require no additional hardware. As well as 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’s user interface.
