Rohde and Schwarz RT-ZM130 Modular Probe Amplifier, 13 GHz, Multimode

The Rohde & Schwarz RT-ZM130 is a modular probe amplifier delivering greater than 13 GHz bandwidth for high-frequency signal acquisition in demanding test environments. Its multimode architecture enables switching between single-ended, differential, and common-mode measurements without probe reconfiguration, powered by a dedicated high-speed ASIC. The amplifier achieves sub-35 ps rise time and 80 V/ns slew rate, ensuring precise capture of low-amplitude signals with minimal noise.

Technical Specifications

• Bandwidth: >13 GHz (realtime)


• Rise Time: <35 ps


• Slew Rate: 80 V/ns (10:1 attenuation, probe input referenced)


• Propagation Delay: 5.5 ns


• Attenuation Settings: 10:1 or 2:1


• Input Resistance: 400 kΩ (differential mode), 200 kΩ (single-ended mode)


• Dynamic Range: ±2.5 V (10:1), ±0.5 V (2:1)

Key Features

• MultiMode Operation: Single probe tip switches between measurement modes without reconnection; offset compensation extends operating range to ±16 V DC offset independent of probe amplifier dynamic range


• Low-Noise Amplification: Optimized for accurate measurement of small-signal components in complex waveforms


• Integrated High-Precision Voltmeter (R&S®ProbeMeter): Simultaneous DC measurement at 0.05% or 0.1% accuracy, independent of oscilloscope settings


• On-Probe Control: Micro button supports oscilloscope-configured functions including run/stop, auto set, waveform save, and trigger level automation


• Modular Tip Compatibility: Integrates with probe tip modules and amplifier stages across the 1.5 GHz to 16 GHz bandwidth range

Typical Applications

• High-speed digital and mixed-signal circuit characterization


• Low-amplitude signal measurement in RF and microwave systems


• Differential and single-ended probing of integrated circuits and PCB traces


• DC offset compensation in wide-bandwidth transient analysis

Compatibility & Integration The RT-ZM130 integrates with the Rohde & Schwarz oscilloscope ecosystem through modular probe architecture. Multimode tip modules connect to dedicated amplifier stages, maintaining signal integrity across the full 13 GHz bandwidth.
