USB 2.0协议分析仪 PCI Express协议分析仪 关于我们  
说明
  • 符合PCI Express 1.1 (2.5 GBit/second)
  • 用户可选 x4, x2 和 x1 链接宽度配置
  • 用户可选 2 Gigabyte 至 64 Kilobyte捕获缓存。当保存到硬盘时,可选的捕获缓存容量适用于更小的数据文件。
  • 强大的 48 MHz Cypress FX2LP微处理器在一个完全的捕获之后通过USB 2.0实现按需上传数据。使你能够在捕获后马上观看数据,无需等待漫长的上传全部踪迹数据。
  • 一个Altera Arria II GX FPGA包含PCI Express x4收发器、DDR2内存控制器和数据上传接口至微处理器
  • 可编程序列探测器允许FPGA探测预定义和定制数据序列的位置。这有助于捕获之后硬件加速PCI Express协议条款探测,接着,这使软件能够在完全捕获之后显示数据非常快,无需软件定位PCI Express数据包和命令集捕获。
  • 一个8-级触发,每个触发等级可达2048 byte深度数据探测,可在非常长的数据序列上进行触发。
  • TTL-兼容触发进/出端口,可同步外部测试仪器。
  • 包含x4插槽探头带有1米电缆。第三方、定制探头也可用于2500A。
  • 微处理器固件和FPGA配置可自动用PC应用软件进行升级。无需单独的和负责的硬件预编程。

总之,2500A硬件和软件的开发着眼于效率最大化和使用简单。硬件小到可以装入你的口袋,软件也非常容易用,并且整套都非常灵活和强大。

独有的先进功能
  • The Hierarchical Protocol Tree View organizes the captured PCI Express protocol data into a format that exactly reflects the nesting of the actual protocol items on the bus. This greatly eases understanding of the PCI Express protocol. Other PCI Express Protocol Analyzers use a primitive block-type display which makes it very hard to see the overall hierarchy of the complex data being communicated.
  • FPGA hardware acceleration (indexing) of protocol items allows instantaneous Protocol View display after custom filtering, even for a full 2 gigabyte capture. Other Protocol Analyzers use the computer's CPU to parse the captured data which is orders of magnitude slower.
  • Dynamic on-demand data upload from the hardware allows effortless access to and browsing of gigabyte sized trace data without a need to first upload the complete data to the PC. Only the part of the Protocol View that is actually visible will result in data fragments being uploaded from the 2500A unit.
  • Extremely deep Trigger Sequence Detectors allow detection of eight trigger levels of up to 2,048 bytes per level or in total 16 kilobytes. Other Protocol Analyzers normally only allow you to trigger on a few DWords of packet payload data.
  • Multiple time-correlated views of the data are simultaneously available, allowing you to easily see transaction, packet and lane details from the highest to lowest abstraction levels at a glance. Some other PCI Express Protocol Analyzers require you to change the protocol view to view the data at a different abstraction level, resulting in lengthy reparsing of the data as well as loss of situational awareness of your location within the overall trace.
  • Hardware acceleration of Protocol Item detection allows immediate display of the number of each type of protocol item in the trace as well as immediate jump to or filtering of any protocol item type.
  • The 2500A unit is significantly smaller than competing PCI Express Protocol Analyzers, allowing it to be easily transported in your pocket or laptop bag (dimensions/weight is only 4.90” x 4.10” x 1.4” / 16oz or 125 x 105 x 35 mm / 450g).

软件概述

The 2500A software runs on Microsoft Windows XP and newer operating systems. Both x86 and x64 systems are supported. The .NET Framework 2.0 is required.

正宗的威尼斯网投平台The 2500A software supports the following features:

  • The trigger position can be adjusted within the capture buffer (i.e. pre or post trigger).
  • Lane Polarity, Lane Mapping and Descrambling can be adjusted / disabled as needed.
  • The software dynamically acquires the data required to display the visible part of the trace as the data is browsed. This results in very quick and effortless browsing of the captured data regardless of the capture buffer size used.
  • Multiple Views of the data are time-correlated; the Protocol View displays a hierarchical view of all Transactions as well as the Packets included within the transactions; the Lane View displays the raw data and control characters as they were received on the link under test; finally, the Detail View decodes details of the packet selected in the Protocol View. Together, these views give you a quick and easy way to browse the captured data from the highest to lowest information level.
  • All Protocol Items in the trace are displayed in the ‘Node Finder’ View. This view allows direct jump to any protocol item in the trace. The Node Finder can also be used to hide / show packets of a particular type.
  • The ‘Search View’ allows you to search for binary or string data in packet payload. Multiple searches can be started and run in the background as you continue working with the software. The Search View allows direct jumps to the search result locations.
  • The ‘Markers View’ displays the trigger position as well as any markers you have added to the capture. Markers are saved with the project and allow you to quickly locate interesting areas in the trace at a later time.
  • Protocol Item Filtering allows you to instantly hide any given Protocol Item Type from the Protocol View. Due to the dynamic data access of the Protocol View, filtering is very quick, even for a full 2 Giga-byte capture.
  • The Protocol View and Lane View data can be exported to file in XML format and to the clipboard in CSV format. This allows easy post-processing of the captured data via your own or 3rd party software.
  • Time can be shown in absolute (measured from capture start) or relative (measured from prior protocol item) mode.
  • Protocol View and Lane View data can be print previewed as well as printed.

正宗的威尼斯网投平台For best performance we recommend a newer Core i5 or Core i7 PC to be used. The minimum recommended PC requirements are a P4 / 2 GHz machine. The data upload speed as well as the Protocol View Filtering speed will be improved with the faster machines.
