Real-time processing and peak detection for PCIe digitisers

March 25, 2014 // By Graham Prophet
Agilent has introduced next-generation real-time peak detection as one of the additional functions for its PCIe high-speed digitisers, starting with the U5303A 12 bit digitiser.

“Use of the U5340A FPGA development kit, a powerful FPGA design set of tools, has allowed us to concentrate on the specific, real-time signal processing requirements identified by our customers as key parameters without worrying about making the ‘plumbing’ work,” said Eduardo Garcia, Agilent FPGA firmware design engineer for digitisers. “This has enabled delivery of the peak detection on-board data processing option. It features capabilities such as baseline stability, and the self-trigger mode, which allows unequaled synchronous noise reduction.”

These functions address very specific needs of OEM customers or research institutes in applications such as high-speed medical imaging, LIDAR laser ranging, environmental monitoring, analytical, and non-destructive testing. Several data processing algorithms can be hosted at the same time in the FPGA, allowing easy and fast switching from one to the other using the high-speed digitiser driver. Data reduction and storage at the digitiser level reduces the data transfer volume by orders of magnitude, and the downstream analysis speed is highly increased.
