Overview

The X3-Servo module features 12 simultaneously sampling A/D and DACs with an FPGA computing core. Low latency SAR A/D and fast-settling DACs support real-time servo control applications. The programmable input range and high input interface directly to many sensors, while the output is capable of driving many transducers. Front panel digital IO can be also be used as PWM or process controls.

Clock and trigger controls include support for consistent servo loop timing, counted frames, software triggering and external triggering. The sample rate clock is either an external clock or on-board programmable PLL clock source.

Data acquisition control, signal processing, buffering, and system interface functions are implemented in a Xilinx Spartan3A DSP, 1.8M gate device. Two 1Mx16 memories are used for data buffering and FPGA computing memory.

The logic can be customized using VHDL and MATLAB using the FrameWork Logic toolset. The MATLAB BSP supports real-time hardware-in-the-loop development using 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 both high data rates to the host that 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.
