A precision, low-jitter timebase or external clock is used for sample rate generation. Sample rates up to 20 MSPS, with <10 kHz programmable resolution, are supported as well as external clocking. Trigger methods include counted frames, software and external triggering.
Data acquisition control, signal processing, buffering, and system interface functions are implemented in a Xilinx Spartan3 1.8M gate FPGA. Two 1Mx16 memory devices are used for data buffering and FPGA computing memory.
The logic can be fully customized using VHDL and MATLAB using the FrameWork Logic toolset. The MATLAB BSP supports hardware-in-the-loop development using the Simulink block diagram environment with Xilinx System Generator.
The PCI Express interface supports continuous data rates up to 180 MB/ s between the module and the host. A flexible data packet system implemented over the PCIe interface provides high data rates to the host and is readily expandable for custom applications.
This extremely versatile module is easily adapted for use in virtually any type of system. Our XMC carrier adapters offer conduction and convection cooling and are available for a range of interfaces including Desktop PCI, Desktop PCI Express, Cabled PCI Express, CompactPCI, and PXI/PXI Express. This module is also readily installed into Innovative Integration’s eInstrument Embedded PC, SBC-ComEx Single-Board Computer, and Andale Data Loggers.
