Keysight applies 12-bit high-speed PCIe card to Optical Coherence Tomography

January 27, 2015 // By Graham Prophet
Keysight Technologies’s U5303A high-speed data acquisition 12-bit PCIe card, resulting from a collaboration with YellowSys, a provider of IP processing firmware and software, is now available with an option dedicated to optical coherence tomography (OCT) technology.

The Keysight data acquisition solution uses signal resampling which provides on-board enhancement of range analysis and offers a stable ADC signal sampling cadence. The solution focuses on clock stability while acquiring the signal in order to avoid sampling cadence changes. This adverse effect on signal acquisition typically occurs when an external k-clock is used. Signal processing is done in real time directly on the data acquisition card, significantly reducing the processing load on the host computer.

The solution was designed using Keysight’s U5340A FPGA development kit, allowing portability of the OCT signal processing IP to other Keysight data acquisition cards, including future releases. There is no need for internal circuitry dedicated to OCT, and the easy migration of the processing IP is a key to future OCT technology developments.

“OCT technology is evolving at a fast pace and we strongly believe in supporting developers to push the limits in real-time imaging and quality,” said Didier Lavanchy, operations manager of Keysight’s high-speed digitizers division. “Partnering with  YellowSys enables us to meet the application demands using our FPGA development kit.”
