Rohde & Schwarz RTO1044 4 Ch 4 GHz Digital Oscilloscope

The Rohde & Schwarz RTO1044 is a 4-channel digital oscilloscope delivering 4 GHz bandwidth and 10 GSa/s sampling rate per channel for high-fidelity signal capture and analysis. Built for signal integrity validation, digital design debugging, power electronics characterization, and automotive radar development, this instrument combines deep 2 Gpts memory per channel with 16-bit vertical resolution to resolve transient events and capture complex waveforms with precision. The 10.1" touchscreen display refreshes at over 250,000 waveforms/s, enabling real-time signal monitoring across four independent channels with DC gain accuracy of ±1%.
