Keysight launches U5303A 12-bit PCle high-speed data acquisition card

Keysight Technologies has introduced the U5303A 12-bit PCIe high-speed data acquisition card, developed in collaboration with YellowSys. This new solution is tailored specifically for optical coherence tomography (OCT) applications, offering enhanced performance and flexibility. YellowSys specializes in IP processing firmware and software, making this partnership a strategic move to advance OCT technology. The U5303A leverages signal resampling techniques to provide on-board enhancements for range analysis, ensuring a stable ADC sampling rhythm. By focusing on clock stability during signal acquisition, the system avoids disruptions that could otherwise affect sampling accuracy. Using an external k-clock can often introduce instability, but Keysight's design minimizes such risks. Additionally, real-time signal processing occurs directly on the data acquisition card, significantly reducing the computational burden on the host system. This innovative approach not only improves efficiency but also allows for greater scalability. The solution was built using the Keysight U5340A FPGA Development Kit, enabling users to transfer OCT signal processing IP to other Keysight data acquisition cards, including future models. This flexibility eliminates the need for dedicated hardware, making it easier to adapt to evolving OCT requirements. Moreover, the IP can be easily transitioned, supporting long-term development and innovation in the field. Didier Lavanchy, Business Manager of Keysight’s High-Speed Digitizer business unit, emphasized the importance of this collaboration: “OCT technology is advancing rapidly, and we believe it has the potential to push the boundaries of optical imaging, delivering real-time results with exceptional image quality. Partnering with YellowSys allows us to meet these demands through our FPGA development kit, empowering developers to create cutting-edge solutions.” With this launch, Keysight continues to support the growing needs of the OCT industry, providing reliable, high-performance tools that enable researchers and engineers to achieve more accurate and efficient imaging results.

Stackable Battery

Features

1. Modularity: Stackable batteries are designed with modular units that can be added or removed as needed to match the required energy storage capacity. This modularity facilitates easy scaling up or down of the battery system without having to replace the entire unit.
2. Safety: These systems often incorporate safety mechanisms to prevent overcharging, overdischarging, and thermal runaway, which is crucial for maintaining the reliability and longevity of the battery pack.
3. Efficiency: By stacking batteries, it's possible to optimize the system for specific applications, balancing factors like cost, weight, and performance to meet the most efficient configuration.
4. Flexibility: Stacking battery offers the flexibility to adapt to different usage scenarios, from small-scale portable devices to large-scale grid storage solutions.
5. Ease of Maintenance: Since each battery module can be easily accessed and replaced individually, maintenance becomes more manageable and cost-effective.

Stackable batteries represent an innovative approach to energy storage, offering significant advantages in terms of flexibility, scalability, and efficiency. They are particularly valuable in applications where the ability to adjust energy storage capacity according to demand is critical.
