The standard BNC output ensures easy compatibility with most oscilloscopes.

SIGLENT CP4020 AC/DC Current Clamp Probe – 60 A, 200 kHz

The SIGLENT CP4020 is a compact and reliable AC/DC current clamp probe designed for accurate current measurements with oscilloscopes and multimeters. With a bandwidth of DC to 200 kHz and a peak current capability of 60 A, it is ideal for low- to medium-power electronics, power supplies, and industrial troubleshooting.

The CP4020 features two selectable sensitivity ranges (50 mV/A and 5 mV/A), allowing both high-resolution measurement of small currents and safe measurement of higher currents. Its clamp-on design enables non-intrusive current measurement without breaking the circuit, saving time and improving safety.

Thanks to its lightweight construction, long cable, and intuitive controls, the CP4020 is well suited for laboratory use, field service, and educational environments.

Application Example & Use

The SIGLENT CP4020 is ideal for measuring AC and DC current in low- to medium-power electronic systems without interrupting the circuit. Simply clamp the probe around a single conductor and connect it to an oscilloscope via the BNC output to observe real-time current waveforms.

Typical use cases include:

  • Measuring input and output current of switch-mode power supplies

  • Analyzing DC motor and actuator current during startup and load changes

  • Troubleshooting current consumption in embedded and battery-powered devices

  • Monitoring current in industrial control and automation circuits

  • Educational laboratory experiments and electronics training
