DIFI Validation Solutions

Keysight’s DIFI Validation Solutions enable satellite ground system developers to confidently adopt the Digital Intermediate Frequency Interoperability (DIFI) standard. As one of the first organizations certified under DIFI, Keysight provides tools and expertise to validate digital IF architectures that replace traditional analog signal chains. By packetizing IQ data and metadata over IP networks, DIFI allows satellite signals to be digitized at the edge and routed through commercial Ethernet infrastructure, supporting centralized processing, multi-orbit operations, and rapid reconfiguration.

Keysight’s integrated test platform supports emulation, analysis, and benchmarking of DIFI components across diverse mission scenarios. It includes high-performance instruments like the M9484C VXG Vector Signal Generator, N9042B UXA Signal Analyzer, and 89600 VSA software with direct data connectivity. These tools enable engineers to simulate real-world RF environments, measure signal integrity, and validate interoperability between vendor systems. The platform ensures defense-grade performance, scalability, and resilience in joint and coalition SATCOM deployments.

By accelerating integration and reducing hardware dependencies, Keysight’s DIFI solutions help modernize satellite ground systems for the digital era. They support secure communications, flexible architectures, and mission-critical reliability, laying the foundation for next-generation space infrastructure. Whether validating gateway links, transparent payloads, or multi-vendor interoperability, Keysight empowers engineers to meet the demands of dynamic and distributed satellite networks.
