TSP #271 - Rohde & Schwarz Compact 8-Channel MXO3 12-Bit Oscilloscope Review, Teardown & Experiments

Published at : 23 Dec 2025

In this episode Shahriar takes a close look at the all new R&S 8-Channel MXO3 series oscilloscope. Despite its size, the scope retains many of its hardware accelerated functions, such zone & frequency domain triggering as well as fast spectrum modes. You can find the scope here:
