High-Speed PCIe Digitizer Processes Data in Real Time

A PCI Express (PCIe) high-speed data acquisition card is now available with an on-board FPGA for real-time data processing. The U1084A Acqiris data converter is a dual-channel, 8-bit PCIe digitizer card with sampling rates of up to 4 GS/s and bandwidth of 1.5 GHz. The unit incorporates a 15-ps trigger time interpolator (TTI) for accurate timing measurement. Real-time signal processing, provided by the on-board FPGA, is defined by the chosen processing firmware. The card’s PCIe form factor and flexible architecture make it suited for medical imaging, scientific instrumentation, non-destructive testing (NDT) and validation of mixed-signal semiconductors in automated test equipment. Firmware options allow the data converter to perform specific post-processing tasks, and are easily uploaded into the FPGA under program control. The combination of on-board processing and the high speed PCIe bus maximizes data and measurement throughput. A four-lane PCIe card, the U1084A digitizer provides data throughput at up to 650 MB/s. Software drivers for Windows and Linux enable the U1084A data converter to be easily integrated and designed into existing measurement systems as well as exchanged, replaced or upgraded to other high-speed Acqiris-based data converters. The Agilent U1084A high-speed PCIe digitizer with on-board signal processing is available now. AGILENT TECHNOLOGIES INC., Santa Clara, CA. (800) 829-4444.
