The MXO Series oscilloscopes from Rohde & Schwarz are now supported by Chroma’s Power Conversion Device Automated Test System Model 8000 (ATS 8000), expanding the platform’s capabilities for increasingly complex power testing applications. The integration is particularly relevant to high-power and high-channel-count systems, including power infrastructure being developed for AI data centers. Power electronics engineers using the ATS 8000 can now incorporate the advanced measurement capabilities of the next-generation MXO oscilloscopes into automated testing workflows, including real-time waveform capture and analysis.
The rapid expansion of AI infrastructure is driving significant increases in data center power requirements. This is prompting power supply manufacturers to develop solutions capable of handling higher power levels and greater power density, including emerging High-Voltage Direct Current (HVDC) architectures. As these systems become more sophisticated, engineers need automated testing solutions that can efficiently capture waveforms, identify performance issues and support calibration throughout the power system development process. Platforms such as Chroma’s ATS 8000 are designed to support these requirements through automated testing and integration capabilities.
The ATS 8000 is designed to automate the testing of a wide range of power conversion devices and power supplies. With the latest integration, Chroma has added Rohde & Schwarz MXO Series digital oscilloscopes to the range of hardware options that can be incorporated into the test system. Oscilloscopes are a critical component of automated power testing, enabling engineers to capture transient events and dynamic waveforms in real time. The addition of the MXO Series therefore gives ATS 8000 users access to advanced measurement capabilities while maintaining an integrated automated testing environment.

High accuracy for high-voltage testing environments
Based on MXO-EP processing ASIC technology developed by Rohde & Schwarz, the next-generation MXO Series offers waveform capture rates of up to 4.5 million acquisitions per second. This helps reduce measurement blind spots and provides a more accurate real-time representation of the signal behavior. With advanced digital triggering, adjustable sensitivity and exceptionally low trigger jitter, the MXO can detect even very small signal anomalies with pixel-level trigger accuracy. In HD mode, the oscilloscopes support up to 18-bit resolution and input sensitivity as low as 0.5 mV/div.
High channel count for high-density power delivery
To meet the power demands of high-density power delivery in AI-driven data centers, a single power rack often needs to support multiple power modules, as well as battery backup units (BBU) and capacitor backup units (CBU) in series or parallel setups. These requirements can create complex measurement challenges involving more than eight channels. The MXO Series includes models with up to eight channels and supports
multi-instrument synchronization through the Rohde & Schwarz ScopeSync architecture, allowing several instruments to operate in a primary-secondary setup with up to 24 synchronized channels. This capability supports debugging work and helps align manual checks with automated test results.
Flexible test platform for real-world applications and production line environments
Thanks to Chroma’s PowerPro 5 control software, engineers can adapt the test systems to specific use cases and run external programs written in C# or Python as part of the test flow. This makes it possible to add custom analysis steps, such as decoding control frames from serial communication buses or applying product-specific calibration routines, meeting engineers’ flexibility requirements in both real-world applications and production-line environments.

Evan Tsai, Product Manager for ATS 8000 Software Solutions from Chroma said: “Drawing on many years of experience in automated testing, we consider efficiency and flexibility to be extremely important in the AI-driven era. The addition of support for the Rohde & Schwarz MXO Series oscilloscopes expands the ATS 8000 platform in response to new demands in advanced power testing. Looking ahead, Chroma will continue to develop automated testing technologies that provide power supply manufacturers worldwide with more comprehensive, precise and reliable measurement solutions, jointly paving the way for highly efficient AI-driven energy systems.”
Jithu Abraham, Director Product Management Oscilloscopes at Rohde & Schwarz said: “Power electronics engineers developing complex power systems used in AI data center infrastructure need measurement tools that can capture fast signal behavior and support complex multi-channel setups. By adding our MXO Series to Chroma’s well-established ATS 8000 platform, these users can now access next-generation oscilloscope technology within their existing automated test workflows.”
