Keysight Technologies, Cambridge Industries Group Accomplish Inter-Operability Testing of O-RAN Radio Units
August 6, 2020 | Business WireEstimated reading time: 1 minute
Keysight Technologies, Inc., a leading technology company that helps enterprises, service providers and governments accelerate innovation to connect and secure the world, announces inter-operability development testing (IODT) of O-RAN radio units (O-RUs) in collaboration with Cambridge Industries Group (CIG), a leading original design manufacturer (ODM), headquartered in Shanghai, China.
The testing was accomplished using CIG’s O-RU and Keysight’s Open RAN Studio, signal source and analyzer solutions to create an environment for 5G new radio (NR) modulation analysis. As a result, CIG and other vendors of O-RUs can accelerate design verification of products based on specifications set by the O-RAN Alliance. CIG is part of a network infrastructure ecosystem that is using O-RAN fronthaul interfaces to unlock the full potential of an open RAN architecture.
“We rely on partners such as Keysight to effectively develop and validate open RAN standards-based network elements, including small cells and O-RAN compliant radio and distributed units,” said Haibo Zhao, founder, chief technology officer (CTO) at CIG. “Working with Keysight, with cross-domain expertise, enables CIG to derive insights critical in the design and manufacturing of a flexible infrastructure that serves diverse use cases for consumers and vertical industries.”
Keysight, the first test vendor to launch O-RAN distributed unit (O-DU) emulation software for validating O-RAN compliant O-RUs, has helped speed development of conformance validation and verification of interoperability between O-RUs and O-DUs. Keysight’s Open RAN Studio integrates with the company’s PathWave signal generation and vector signal analysis (VSA) software for advanced modulation analysis of signal and radio performance.
“Together with key partners such as CIG, we are advancing the development of a disaggregated, virtualized network architecture based on O-RAN specifications,” said Giampaolo Tardioli, vice president of Keysight and general manager of Keysight's Network Access Group. “The future of pervasive wireless connectivity requires end-to-end performance verification of 5G network elements across multiple domains including, radio frequency (RF), mmWave and O-RAN protocol.”

Digital Twin Concept in Copper Electroplating Process Performance
07/11/2025 | Aga Franczak, Robrecht Belis, Elsyca N.V.PCB manufacturing involves transforming a design into a physical board while meeting specific requirements. Understanding these design specifications is crucial, as they directly impact the PCB's fabrication process, performance, and yield rate. One key design specification is copper thieving—the addition of “dummy” pads across the surface that are plated along with the features designed on the outer layers. The purpose of the process is to provide a uniform distribution of copper across the outer layers to make the plating current density and plating in the holes more uniform.

Elementary, Mr. Watson: Rein in Your Design Constraints
07/10/2025 | John Watson -- Column: Elementary, Mr. WatsonI remember the long hours spent at the light table, carefully laying down black tape to shape each trace, cutting and aligning pads with surgical precision on sheets of Mylar. I often went home with nicks on my fingers from the X-Acto knives and bits of tape all over me. It was as much an art form as it was an engineering task—tactile and methodical, requiring the patience of a sculptor. A lot has changed in PCB design over the years.
