Rohde and Schwarz RT-ZM60 Modular Probe Amplifier, 6 GHz, Multimode

The Rohde & Schwarz RT-ZM60 is a modular probe amplifier delivering 6 GHz bandwidth for high-frequency signal acquisition across multimode measurement configurations. Part of the R&S®RT-ZM modular probe system, this amplifier combines high probing bandwidth with dynamic range switching and minimal capacitive loading - delivering rise times under 75 ps for fast transient capture.

Technical Specifications

• Bandwidth: Greater than 6 GHz


• Rise Time: Less than 75 ps


• Input Impedance: 400 kΩ differential mode; 200 kΩ single-ended mode


• Operating Voltage Window: ±5 V plus DC offset voltage


• DC Offset Voltage Compensation: ±16 V across all operating modes


• Maximum Non-Destructive Input Voltage: ±30 V
