Enabling the Next-Generation Vector Signal Analyzer with MSI MS-CF02 H610 Mini-ITX Board

Background

To meet growing demands for higher bandwidth, lower noise, and better modularity in RF signal testing, a leading instrument manufacturer set out to develop a next-generation Vector Signal Analyzer (VSA). The goal was to offer a compact, high-performance analyzer capable of advanced signal analysis, remote monitoring, and long-term deployment in both lab and production environments.

This development was an evolution from the company’s previous generation VSA, which was based on a legacy x86 micro-ATX platform using 6th/7th Gen Intel® Core™ processors. The older platform had limitations in scalability, power efficiency, and I/O modernization.

Challenge

• The previous generation VSA used a traditional micro ATX industrial motherboard with higher thermal output and limited I/O.
• Legacy I/O interfaces, large footprint, and short CPU lifecycle made it unsuitable for long-term embedded use.
• A modern VSA design required:
  • Smaller footprint for integration into compact enclosures
  • Support for high-speed data acquisition and processing
  • Future-proof I/O interfaces and storage options
  • Industrial-grade reliability with fanless operation support

Solution: MSI MS-CF02 H610 Embedded Board

To support the next-generation architecture, the engineering team selected the MS-CF02 H610, a Mini-ITX industrial motherboard by MSI designed for embedded and edge computing applications.

Key Reasons for Selection:

System Use Case

In the new VSA system:

• The RF front-end handles signal capture and I/Q demodulation.
• The MS-CF02 serves as the main system controller, executing FFT, spectrum analysis, EVM calculation, and visualization.
• Data is stored on M.2 SSDs and displayed via HDMI in a responsive GUI.
• COM ports and LAN are used for synchronization with external test equipment and automation systems.

Outcome

• Performance boost: Signal processing times improved by over 40% vs. previous generation.
• Reduced size: Mini-ITX platform enabled a 30% smaller mechanical design.
• Power efficiency: Passive cooling design enabled in fanless configurations.
• Scalability: Modular architecture allows future upgrades (e.g. 5G modules, edge AI coprocessors).
• Ease of integration: Pre-tested Linux and Windows 10/11 compatibility streamlined development.

Conclusion

By adopting the MSI MS-CF02 H610, the development team successfully transitioned from a legacy platform to a compact, modern embedded solution—laying the foundation for a next-generation VSA that is smaller, faster, more reliable, and future-ready. The MS-CF02 enables test and measurement equipment manufacturers to scale their RF solutions while simplifying thermal design, integration, and long-term product support.
