The Keysight N7042A Rogowski coil current probe measures AC currents up to 300 A, with bandwidth ranging from 9.2 Hz to 30 MHz. The probe has a thin, lightweight, flexible, and simple-to-use clip-around Rogowski coil that enables current measurement in the most difficult-to-reach parts and confined spaces of a circuit under test. It can also measure large AC current without an increase in transducer size.

The N7042A series is ideal for measuring AC current in the presence of large DC current. You can use the probes to design, debug, and troubleshoot power semiconductor circuits, power supplies, inverters, and motor drives. These probes come with an AC power adapter and 4x AA batteries. Use them with any Keysight oscilloscope with a 1 MΩ input BNC interface.
