Rohde & Schwarz RTO2044 4GHz Digital Oscilloscope

The Rohde & Schwarz RTO2044 is a 4 GHz benchtop digital oscilloscope engineered for signal analysis across four analog channels. It delivers maximum real-time sampling rates of 20 Gsample/s on two channels or 10 Gsample/s on four channels, with an acquisition rate exceeding 1,000,000 waveforms per second. The instrument captures up to 2 Gsample of memory depth, enabling detailed analysis of extended signal sequences.

Vertical resolution reaches 16 bits in high-definition mode without sampling-rate reduction, exposing subtle signal details with exceptional clarity.
