Overview
Rohde & Schwarz current probes make non-intrusive DC and AC measurements accurately. The range spans currents from 1 mA to 2000 A and bandwidths up to 120 MHz. Rohde & Schwarz also offers Rogowski wideband current probes for power electronics and EMC work: a Rogowski coil combines excellent bandwidth with a flexible coil and low insertion loss, which is what AC and transient current measurement wants. The RT-ZC series comes in two interface flavours: B models use the Rohde & Schwarz probe interface, plugging straight into the oscilloscope with no external supply, while standard models use a BNC connector and take the RT-ZA13 external supply or run on batteries.
Key features
- Non-intrusive measurement: the clamp-on design measures DC and AC current safely without breaking the circuit
- Very wide current range, 1 mA to ±2000 A, from microcurrents to heavy currents
- Bandwidth up to 120 MHz: the RT-ZC20B / RT-ZC30 / RT-ZC31 reach 100 MHz to 120 MHz and capture fast current transients
- Two interface types: B series probes are detected and powered through the R&S probe interface, standard models use BNC and work with any oscilloscope
- Multiple ranges: the RT-ZC31 switches between 30 A / 5 A / 0.5 A, so one probe covers a wide span
- The RT-ZC02 handles heavy low-frequency currents: battery powered, 20 kHz bandwidth, two ranges at ±200 A / ±2000 A, for measurement on site
- Rugged industrial build in quality materials, for long-term use in the laboratory and in the field
- The RT-ZF20 deskew fixture aligns a voltage probe against a current probe in time, which is what accurate power measurement depends on
Typical applications
- Power electronics design verification: switching current waveforms in SMPS, DC-DC converters and motor drives
- Electric vehicle and charging system test: high-current charging stations, battery management systems (BMS), inverter currents
- EMC pre-compliance: measuring conducted current to trace the source of interference
- Industrial power monitoring: current quality analysis on three-phase systems, UPS units and variable frequency drives
- Semiconductor device characterisation: switching behaviour and losses on GaN and SiC power devices
- Safety and compliance testing: standby and leakage current measurement against IEC/EN safety standards
