As artificial intelligence (AI) continues to advance, global demand for high-power, high-density power systems in data centers is growing rapidly. To address NVIDIA's new ±400V / 800V HVDC (High-Voltage Direct Current) power architecture, power supply manufacturers are actively developing higher-power and higher-density solutions, placing increasing demands on testing accuracy, efficiency, and system integration. To keep pace with evolving industry requirements, Chroma's ATS 8000 Power Conversion Device Automated Test System offers extensive instrument integration capabilities, enabling users to flexibly configure automated test systems with a wide range of compatible instruments. The addition of support for the Rohde & Schwarz (R&S) MXO Series digital oscilloscopes is one example of how Chroma continues to expand the platform's instrument compatibility to meet diverse testing needs.
Integration of Advanced R&S MXO Waveform Measurement Technology
In automated power testing applications, digital oscilloscopes play a critical role in capturing dynamic waveforms in real time. Chroma ATS 8000 now supports the next-generation MXO Series digital oscilloscopes from Rohde & Schwarz (R&S), integrating their advanced waveform measurement capabilities into automated test workflows.
Based on proprietary ASIC technology developed by Rohde & Schwarz, the R&S MXO Series offers waveform capture rates of up to 4.5 million acquisitions per second, helping minimize measurement blind spots and provide an accurate real-time representation of signal behavior. In addition, the series features advanced digital triggering technology with adjustable sensitivity and exceptionally low trigger jitter, enabling precise detection of small signal anomalies with pixel-level trigger accuracy. In High Definition mode, the oscilloscopes support up to 18-bit resolution and input sensitivity as low as 0.5 mV/div, providing a high-accuracy measurement platform for high-voltage testing environments.
Supporting Multi-Channel Measurement Requirements for AI Power Systems
To meet the 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 (BBUs) and capacitor backup units (CBUs) in series or parallel configurations. These requirements can create complex measurement challenges involving more than eight channels. The R&S MXO Series digital oscilloscopes feature ScopeSync technology, supporting a Master/Slave architecture that enables high-speed, real-time digital synchronization of multiple oscilloscopes, greatly assisting engineers with debugging and comparing automated measurement results.
Whether for dynamic response analysis during power supply development, troubleshooting, or waveform capture and result verification in automated testing, Chroma ATS 8000 leverages its continuously expanding instrument integration capabilities to help customers establish test environments tailored to their specific application requirements.
Chroma ATS 8000 & PowerPro 5: A Test Platform Built on Decades of Industry Expertise
Unlike general-purpose development tools, Chroma's PowerPro 5 software platform is built on decades of power testing experience. Refined through long-term collaboration with leading global manufacturers, it incorporates extensive industry knowhow and technical expertise.
PowerPro 5 allows users to integrate custom external programs written in C# or Python directly into the testing workflow. For example, in server power communication testing, hexadecimal status and error codes obtained via PMBus can be decoded using Python scripts, allowing the system to interpret the corresponding error messages and verify them against expected results.
For proprietary or non-standard calibration formulas, users can develop external programs in C#. The Chroma ATS 8000 then inputs the instrument readings for precise product calibration.
Continuously Expanding Automated Test Platform Integration Capabilities
By supporting the R&S MXO Series digital oscilloscopes, Chroma ATS 8000 further expands its integration capabilities for advanced waveform measurement and multi-channel testing, providing customers with greater flexibility in instrument selection and automated testing applications. As AI data centers and next-generation high-power architectures continue to evolve, Chroma remains committed to advancing power testing technologies and system integration capabilities, delivering more comprehensive, accurate, and reliable automated test solutions to power supply manufacturers worldwide.
