USB Advisor為LeCroy 第一部USB2.0 分析儀 . 此系統採取獨立式平台 , 搭配128 M記憶深度可紀錄各式異常信號及狀況 . USB Advisor是USB2.0+ USB1.1協定分析儀模組 , 簡易的操作設定簡化了工程師操作上的時間 . 搭配CATC Trace View 工具 , 使的信號分析變的更加簡單 .


多種顯示層級
主要功能
  • CATC Trace Analysis Software System - Faster interpretation and debug of USB traffic
  • Records USB 2.0 traffic - Supports all three USB speeds (High (480Mbps), Full (12Mbps) and Low (1.5Mbps))
  • 128 MByte Recording Capacity - Extend capture windows to several minutes with real-time hardware-based filtering
  • BusEngine Protocol Processor technology - Sophisticated triggering helps isolate important protocol traffic, specific errors or data patterns
  • Dual Recording Channels - Simultaneously record High speed traffic on one channel and low/full speed traffic on the other
  • Advanced Triggering - Trigger and filter on both channels to easily isolate important traffic, specific errors or data patterns
  • Real-Time Statistics - View bus traffic as it occurs even if a Trace is not being recorded
  • Hardware Filtering - Automatically exclude non-essential and redundant packets from the trace
  • Intelligent Reporting - Quickly identify and track error rates, abnormal bus or timing conditions
  • Sophisticated Viewing - View Packet, Transaction and Transfer layers of the USB protocol
  • 3 Year Hardware Warranty - Protect your investment with industry leading warranty

看了就能了解的USB Protocol
我們使用CATC Trace 分析軟體來協助分析所擷取的的資訊 . 採用快速翻譯搭配不同顏色的區塊 , 讓使用者可以一目瞭然所擷取的的訊號 , 搭配不同層級顯示如: Packet, Transaction and Transfer. 更可以得到更多不同的應用訊息與內容.
在層級翻譯中 , 亦提供了如 Picture Transfer Protocol /Still Image Class Decoding, PictBridge, Media Transfer Protocol (MTP), SCSI Mass Storage, Bluetooth HCI, Printer, Human Interface Devices (HID), Cable Based Association Framework, Audio, Communication, Host and Device Wire Adapter 等Class 及Endpoint 解譯功能 , 十分的便利.



The CATC Trace display uses collapsible headers to group all frames and transactions that are part of a single transfer

快速搜尋及報告功能
USBTracer/Trainer 提公非常多種搜尋功能及報告功能 . Bus Utilization 可以提供包含了graphs data, packet length, bus usage by device other statistical data. Bandwidth calculator 能夠自動的計算頻寬傳輸效益 .
使用Traffic Summary 視窗, 使用者能夠快速的計算及了解畫面中的資訊, 包含各封包次數 , 各層級模式狀態 , 各流量狀況及錯誤發生次數及位置 . 大量節省使用者的時間 .
強大的搜尋器則能夠輕易且快速的尋找任依封包及訊息的位置 .




Traffic summaries provide detailed metrics for USB events within a trace

簡易設定的進階觸發
對於USB系統而言有效率的分析器必須讓使用者在訊號擷取到有用的訊息 , 並且準確鑑定和選擇記錄感興趣的部份 . USBTracer 分析器提供硬體觸發功能  . 另外 , 透過錯誤分析及觸發用戶能容易紀錄信號中異常位置的狀態 . 用戶能指定多達 7 階的排序 . 例如︰ 在Transaction 發生5次後所產生的錯誤加以觸發 .
