DESCRIPTION:

The Rohde & Schwarz MXO44-245 combines four analogue channels with 500 MHz bandwidth in the next-generation MXO 4 oscilloscope platform. Designed around Rohde & Schwarz's latest oscilloscope architecture, the instrument delivers industry-leading waveform acquisition performance, true 12-bit vertical resolution, deep acquisition memory, advanced spectrum analysis, and precision triggering capabilities within a compact laboratory instrument.

At the core of the MXO44-245 is a true 12-bit analog-to-digital converter operating at full resolution across all sample rates. Compared with conventional 8-bit oscilloscopes, the architecture provides sixteen times greater vertical resolution, enabling engineers to identify low-level signal details, power rail ripple, switching noise, transient disturbances, jitter effects, and signal integrity issues with substantially improved clarity. HD mode further extends effective resolution to as much as 18 bits for precision measurement applications.

The oscilloscope supports sampling rates up to 5 GSa/s and provides 400 Mpoints acquisition memory per channel as standard. This deep memory architecture enables long-duration waveform captures while maintaining fine timing resolution, making the MXO44-245 particularly effective for analysing embedded processors, industrial control systems, power converters, communications interfaces, motor drives, and complex transient events.

A defining feature of the MXO 4 platform is its acquisition performance. The MXO44-245 captures more than 4.5 million waveforms per second while maintaining up to 90% real-time signal visibility. This dramatically improves the probability of detecting intermittent faults, rare glitches, timing violations, protocol errors, and sporadic disturbances that may remain hidden on conventional oscilloscopes.

Integrated spectrum analysis performs up to 50,000 FFT calculations per second using dedicated spectrum acquisition hardware. Independent time-domain and frequency-domain controls allow engineers to perform EMI investigations, harmonics analysis, RF troubleshooting, switching power supply development, and mixed-domain debugging without requiring a dedicated spectrum analyzer.

Advanced digital triggering capabilities include edge, pulse width, runt, glitch, timeout, setup-and-hold, logic, serial bus, zone, spectrum, and math triggering. Trigger jitter below 1 ps and trigger rearm times below 21 ns provide exceptional event isolation capability for demanding validation and troubleshooting applications.

The large 13.3-inch Full HD capacitive touchscreen provides extensive workspace for waveform analysis, protocol decoding, FFT measurements, automated measurements, and mixed-domain investigations. The platform can be expanded with optional mixed-signal capability, arbitrary waveform generation, protocol analysis packages, power analysis tools, and frequency response analysis functionality.
