產品介紹
產品定位與應用Keysight / Agilent / HP E4406A Agilent E4406A 向量頻譜分析儀 Vector Spectrum Analyzer 屬於頻譜與訊號分析設備，適合用於載波、雜訊、諧波、雜散、調變品質、通訊訊號與 EMI 預掃測試等情境。
既有資料中可辨識到 7 MHz – 4 GHz、5 Hz – 10 MHz 等量測範圍線索，實際範圍仍需依選配與機身配置確認。
選型時建議同步確認頻率範圍、分析頻寬、相位雜訊、DANL、前置放大器、追蹤產生器與量測應用軟體，避免後續因選配、治具或校正條件不符而影響測試進度。
弘燁科技可依目前庫存、附件組合、校正需求與交期，協助比對同級替代型號並整理詢價所需資訊。
