The Rohde & Schwarz RT-ZC02 is a Hall Effect AC/DC current probe engineered for non-intrusive measurement of steady-state, transient, and complex waveform currents up to 1000 A. The probe operates from DC to 20 kHz and delivers dual sensitivity modes (0.01 V/A and 0.001 V/A) to accommodate measurement ranges from 200 A to 2000 A, making it ideal for characterizing inverters, switch-mode power supplies, and industrial control circuits. Powered by a single 9 V alkaline battery, the RT-ZC02 connects via BNC to oscilloscopes and multimeters, requiring no circuit interruption during measurement.

– Compatibility & Integration
The RT-ZC02 integrates directly with R&S RTH1000 and RTC1000/RTB2000 series oscilloscopes via predefined probe selection. BNC output enables connection to compatible oscilloscopes and multimeters across test environments. For high-frequency current measurement requiring 100 MHz bandwidth, the R&S RT-ZC20 variant is recommended.
