12位分辨率 含6GHz頻率測量
本公司根據ISO9004制程所生產出的U6200A通用頻率計數器能夠提供每秒12位數頻率分辨率(見Figure-1)、40 ps時間間隔解析，以及完整的測試與分析功能。另外，本產品還內建第三頻道，可量測頻率從375 MHz到6GHz，而和第二頻道，可量測頻率從1 mHz到 to 400 MHz。
的萬用特色
本產品U6200A也提供了其它不錯的功能及設計，例如：頻率比率(每秒11位)、時間間隔、周期(2.5 ns至1000 s)、 工作周期、脈沖寬度、上升/下降時間、峰值電壓( 100 Hz到300 MHz)、相位、總計、時基溫度變化穩定度(小于1 PPM)、老化率(每年小于2 PPM)、時基參考(I/O見Figure-2)、前端隔離。另外還提供20組設定存儲空間，讓使用者儲存常用的設定(見Figure-3)。
完整的數學運算功能及簡易的操作面板
本產品U6200A內建統計及數學運算功能。使用者可以做一般量測、同步量測、中間值統計、/最小值統計、三角函數統計及標準差統計(見Figure-4)。以及運用Scale & Offset功能按鍵，使用者可依實際應用加入補償值。而要完成以上操作并根據需求輸入數值，使用者只需輕易地利用本產品面板上的數字鍵即可。再者，本公司為了使用者操作方便，將功能按鍵設計成當功能啟用時，按鍵便會亮起(見Figure-5)。
快速測量及特殊應用
本產品U6200A采用即時數字信號進程技術，即可在分析數據之際，同時讀取新值并做快速測量。值得一提的是「限值模式」，使用者可以依需求設定及最小值，并通過面板設定成Go-On或Stop，再開啟USB Output，此時只要測量值超過所設定的范圍， U6200A就會按照設定繼續或停止測量，同時輸出信號觸發外部裝置(見Figure-6)。
免費的遠端操控軟件及常用的SCPI指令
使用者除了可以通過微軟Excel應用軟件(見圖九)，經由內建的USB或選購的GPIB接口取得資料，還可以利用U6200A支持網路伺服器功能，將內建的網絡通信接口連結PC ，并在PC上的瀏覽器中輸入預設的位址192.168.0.247，使用者便可通過網絡操作界面GUI(見Figure 10)操控U6200A。另外，靠著與安捷倫53132A相容的SCPI指令集，U6200A能夠在應用上提供使用者熟悉的語法字串。相關指令集信息，請參照使用U6200A使用手冊第七章節。

外部源和輸入放大器噪聲可能會提前或推遲定義測量開始和結束的觸發點。 由此產生的時序不確定性是信號壓擺率和寄生噪聲尖峰幅度（相對于輸入遲滯帶）的函數。
