The Keysight U5303A is a precise 12-bit PCIe digitizer with programmable on-board processing. Benefitting from the very high data transfer rates of the PCIe 2.0 interface, and occupying a single x8 slot in a host PC, the U5303A offers high performance in a small footprint, making it an ideal platform for many commercial, industrial and aerospace & defense embedded systems.

At the heart of the U5303A is a data processing unit (DPU) based on the Xilinx Virtex-6 FPGA. This DPU is responsible for controlling 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. Advance functionalities are available such as real-time averager and peak detection, preserving intrinsic raw digitizer performance. Furthermore, Keysight is supporting the deployment of custom processing algorithm on this digitizer with this U5340A FPGA development kit.
