8-channel digitizer occupies a single PCIe slot
Agilent Technologies now offers an eight-channel version of its U5309A 8-bit single-slot PCIe Gen2 digitizer with onboard processing, increasing channel density and minimizing footprint in embedded OEM applications.
Both the two-channel and eight-channel versions furnish an analog bandwidth of DC to 500 MHz and up to 2 GB of DDR3 memory for long acquisition time. The dual-channel U5309A provides a sampling rate of 2 Gsample/s, while the new eight-channel digitizer provides a sampling rate of 1 Gsample/s. Channels can be interleaved to reach a 2 Gsample/s rate.
An onboard data-processing unit employs a Xilinx Virtex-6 FPGA to control digitizer functionality, data flow, and real-time signal processing. This allows data reduction and storage to be carried out at the digitizer level, minimizing transfer volumes and speeding analysis. In addition, engineers can use the U5340A FPGA development kit to implement custom real-time processing algorithms.
PCIe digitizer gains peak-detection option
A firmware upgrade for the U5303A PCIe 12-bit digitizer from Agilent enables real-time peak detection, while offering baseline stability and a self-trigger mode that reduces synchronous noise.
The PKD (peak detect) option is deployed via the digitizer’s embedded Xilinx Virtex-6 FPGA. This preserves the intrinsic raw digitizer performance, such as the ultra-fast rearm time of less than 500 ns between acquisitions. In addition, engineers can integrate other real-time signal-processing functions using the U5340A FPGA development kit. Several data-processing algorithms can be hosted at the same time in the digitizer’s FPGA, allowing fast switching from one to the other using the high-speed digitizer driver. Data reduction and storage at the digitizer level reduce the data transfer volume by orders of magnitude and increase downstream analysis speed.
The dual-channel U5303A digitizer occupies a single x8 PCIe slot in a host PC. It provides a sampling rate of up to 3.2 Gsamples/s and covers a frequency range of DC to 2 GHz. The digitizer can be used in such applications as medical imaging, LIDAR laser ranging, environmental monitoring, and nondestructive testing.
