本公司根據ISO9004製程所生產出的U6220A萬用計頻器能夠提供每秒12位數頻率解析(見Figure-1)、可量測頻率從1 mHz到 to 400 MHz。
本產品U6220A也提供了其它不錯的功能及設計,例如:週期(2.5 ns至1000 s)、 峰值電壓(100 Hz到300 MHz)、總計、時基溫度變化穩定度 (小於 1 PPM)、老化率(每年小於 2 PPM)、時基參考(I/O見Figure-2)、前端完全隔離。另外還提供20組記憶空間,讓使用者儲存常用的設定(見Figure-3)。
本產品U6220A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、最大/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。而要完成以上操作並依需求輸入數值,使用者只要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)。
本產品U6220A採用即時數位訊號進程技術,即可在分析數據之際,同時讀取新值並做快速量測。值得一提的是「限制模式」,使用者可以依需求設定最大及最小界值,並透過面板設定成Go-On或Stop,此時只要量測值超過所設定的範圍,U6220A就會依設定繼續或停止量測。
使用者除了可以透過微軟Excel應用軟體,經由內建的USB或選購的GPIB介面取得資料,還可以利用U6220A支援網路伺服器功能,將內建的乙太網路連結PC,並在PC上的網路瀏覽器中鍵入預設的位址192.168.0.247,使用者便可透過圖像使用者介面GUI操控U6220A。另外,靠著與安捷倫53132A相容的SCPI指令集,U6220A能夠在應用上提供使用者熟悉的語法字串。
