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.
