Integration of modular signal switching simulation systems

Pickering Interfaces is deploying modular signal switching and sensor simulation technologies for electronic test and verification systems. The implementation addresses the requirement for adaptable commercial off-the-shelf solutions in hardware-in-the-loop and functional test applications within the electronics manufacturing industry.

Operational Challenges and Collaboration
Engineers face complex testing challenges involving system reliability and harsh operating conditions. To address these structural demands, Pickering Interfaces develops scalable hardware and software platforms that integrate with open standard architectures, ensuring long-term system availability and reducing overall development time for test engineers.

Technical Solution and Responsibilities
The technical architecture includes a battery management system hardware-in-the-loop demonstration running on an LXI chassis equipped with supporting cables and connectors. The system utilizes PXI battery simulator modules to replicate stacked cell architectures and PXI fault insertion modules to simulate broken wires and cell shorts. Additionally, the company provides the 41/43-625 PXI/PXIe multi-channel waveform generator analog output modules for signal sourcing, alongside high-power, high-voltage, and high-current PXI switching units.

Deployment and Implementation
The simulation and testing infrastructure is scheduled for demonstration at the electronica India trade fair, located at the Bangalore International Exhibition Centre in Bengaluru, India, from September 16 to 18, 2026. During the implementation phase, engineers utilize Test System Architect, a graphical software toolset designed to configure, visualize, and document complete signal routing paths prior to physical deployment. The operational setup is housed at stand H3.J41 alongside hardware from the company's reed relay and connectivity divisions.

Applications and Use Cases
This modular technology is applied directly in battery management system testing and general electronic component verification. The functional use cases involve generating analog waveforms, sourcing signals, and executing fault insertion to validate the operational safety of electronic assemblies under simulated stress.

Results and Expected Impact
The integration of these standardized switching and simulation modules minimizes engineering errors during the system design phase and accelerates the time-to-market for new electronic products. Regarding the deployment logic, Steve Edwards, Head of Product Management at Pickering, states: "Our flexible and scalable modular systems, built on open standards, ensure long-term availability, reduce development time, and accelerate time-to-market, providing adaptable COTS solutions for current and future needs".
