The Keysight U5303A is an accurate and precise 12-bit PCIe digitizer with programmable on-board processing. Benefitting from the very high data transfer rates of the PCIe interface, and occupying a single slot in a host PC, the U5303A offers high performance in a small footprint, making it an ideal data acquisition platform for many commercial, industrial and aerospace & defense embedded systems.

At the heart of the U5303A ADC card is a data processing unit (DPU) based on the Xilinx FPGA. This DPU controls the module functionality, data flow and real-time signal processing. This powerful feature allows data reduction and storage to be carried out at the digitizer level, minimizing transfer volumes and speeding-up analysis. Advanced functionalities such as specific firmware and application options are also available. Furthermore, Keysight is supporting the deployment of custom processing algorithm on the digitizer with the U5340A FPGA development kit. Integrating algorithms minimizes the need for additional circuitry and exploit the full density and speed of the digitizer.
