Oscilloscope, R&S®MXO 3 Series

Why It Matters

The MX 3’s speed and precision let engineers debug complex designs faster, while its small footprint frees valuable bench space, accelerating product development cycles across electronics industries.

Key Takeaways

• Bandwidth spans 100 MHz to 1 GHz, covering most RF applications
• 4.5 M waveforms per second enable near‑full real‑time capture
• 12‑bit ADC with 18‑bit HD mode delivers superior signal fidelity
• Eight‑channel MSO, built‑in generator, and 11.6″ HD display in 5U rack
• Up to 50 000 FFTs per second for fast frequency‑domain analysis

Pulse Analysis

The test‑and‑measurement market has seen a surge in demand for oscilloscopes that can keep pace with ever‑faster digital and mixed‑signal designs. Rohde & Schwarz, a long‑standing player in RF and microwave instrumentation, addresses this need with the MX 3 series, which pushes acquisition rates to 4.5 million waveforms per second. This capability translates to up to 99% real‑time capture, meaning engineers can observe virtually every transition on a signal without missing intermittent events—a critical advantage when troubleshooting high‑speed serial links or power‑electronics switching. The series also offers a broad 100 MHz‑1 GHz bandwidth, ensuring relevance across a wide spectrum of applications from automotive radar to consumer IoT devices.

Beyond raw speed, the MX 3 differentiates itself through its signal fidelity. A 12‑bit analog‑to‑digital converter provides a solid dynamic range, while an optional 18‑bit high‑definition mode pushes resolution even further for low‑amplitude measurements. Coupled with 125 Mpoints of standard memory and advanced digital triggering, users can capture deep, detailed waveforms and isolate events with surgical precision. Frequency‑domain analysis is equally robust, with up to 50 000 FFTs per second and independent time‑frequency settings, enabling rapid spectral diagnostics without sacrificing time‑domain insight. The integrated eight‑channel mixed‑signal oscilloscope (MSO) and built‑in arbitrary waveform generator streamline test setups, reducing the need for auxiliary equipment.

For engineering teams, the MX 3’s compact 5U rack height and 11.6‑inch Full HD display deliver a high‑performance instrument that fits into crowded lab environments. This space efficiency, combined with the instrument’s extensive feature set, shortens development cycles by allowing faster debug and validation of prototypes. As product timelines tighten and electronic systems grow in complexity, tools like the MX 3 that blend speed, precision, and practicality become essential assets, reinforcing Rohde & Schwarz’s position as a leader in next‑generation measurement solutions.
