Isolated Probe System
R&S RT-ZISO

The R&S RT-ZISO is an isolated probe system designed for highly accurate measurements of fast-switching signals, especially in environments with high voltages and rapid switching operations.

This probe system sets new technological benchmarks for isolated probes and for next-generation power electronics designs based on wide bandgap (WBG) semiconductors such as SiC and GaN.

New technological standards in isolated probe technology.

The R&S RT-ZISO delivers an unprecedented combination of accuracy, sensitivity, dynamic range, and bandwidth. Its power-over-fiber architecture provides full galvanic isolation between the device under test (DUT) and the measurement setup, achieving a significantly higher common-mode rejection ratio (CMRR) than conventional differential probes. This is particularly valuable for high-side gate measurements in complementary circuits, especially when working with wide bandgap devices.

Features & Technical Specifications.

  • Bandwidth: 100 MHz to 1 GHz (expandable)
  • CMRR: >90 dB (>30,000:1) at 1 GHz
  • Input and offset range: ±3,000 V
  • Common-mode range: ±60 kV
  • Sensitive input range: ±10 mV

A wide range of probe tips is available for different measurement requirements, including MMCX (Micro-Miniature Coaxial) connectors, square pins, and wide square pins. All connectors comply with safety requirements for CAT III voltages up to 1,000 V. The long, flexible probe leads allow convenient contacting of test points with minimal mechanical stress.

Optimized for MXO and RTO6 oscilloscopes.

The isolated probe system is ideally suited for oscilloscopes from the MXO family (MXO 4, MXO 5, MXO 5C) thanks to their hardware-based acceleration, as well as for the RTO6 oscilloscope in demanding analysis applications. Using the RT-ZISO with the probe interface of these oscilloscopes is straightforward. The instrument automatically detects and configures probe tip information. Offset and range can be easily adjusted on the oscilloscope. In addition, all oscilloscope features—such as the high acquisition rate and responsive FFT—are fully available for measurements.
