这PXI控制器附带用户可访问的RAM，使用户能够升级工厂安装的RAM数量.此外，用户还可以通过USB CD-ROM或DVD-ROM更换预装的操作系统。除了提供高处理能力之外，这控制器提供高I/O吞吐量，以及高达24 GB的RAM和一套全面的外设I/O端口。

的前面板PXIe国家仪器公司-8861包含显示端口1.2版。这款产品的最高性能PXI嵌入式控制器使其成为PXI控制、测量和测试系统的理想解决方案。本中提供的集成差分系统100 MHz参考时钟控制器提供多个模块的无缝同步。此外，还提供了三条差分星形触发总线，用于分配精确的触发和时钟信号。因此，测井和仪器系统苛刻的同步和时序要求因的集成特性而得以降低倪PXIe-8861.

PXIe-8861

The National Instruments PXIe-8861 is a microprocessor based embedded Controller designed for PXI Express systems. This model features an Intel Xeon 4‑Core processer. For a flexible and advanced level connectivity, the NI PXIe-8861 comes equipped with two USB 3.0 ports, two Gigabit Ethernet Ports (10/100/1000BASE‑TX compatible), four USB 2.0 ports, two Thunderbolt™ 3 ports, one serial port, and other types of peripheral I/O.

The processer equipped in this PXI Controller is a Quad-Core 2.8 GHz processer. This model is an ideal choice for various applications, including data acquisition and RF modular instrumentation. The National Instruments PXIe-8861 is a high bandwidth system controller that can easily be combined with any compatible PXI Express chassis like the NI PXIe-1085.

This PXI Controller comes with user accessible RAM, enabling the user to upgrade the amount of factory installed RAM. Moreover, users can also replace the preinstalled operating system through a USB CD-ROM or DVD-ROM. Apart from offering high processing power, this Controller offers high I/O throughput, coupled with up to 24 GB of RAM and a comprehensive set of peripheral I/O ports.

The front panel of the National Instruments PXIe-8861 contains a Display Port v1.2.  The highest performance of this PXI Embedded Controller makes it an ideal solution for PXI-based control, measurement, and test systems. The integrated, differential system 100 MHz reference clock provided in this Controller offers seamless synchronization of multiple modules. Moreover, three differential star trigger busses are also provided for the distribution of precise trigger and clock signals. Thus, the demanding synchronization and timing requirements of logging and instrumentation systems are curtailed by the integrated features of the NI PXIe-8861.
