產品介紹
產品定位與應用Keysight / Agilent / HP E4440A Agilent E4440A / E4443A / E4445A / E4446A / E4447A 頻譜分析儀 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 3 Hz – 6.7 GHz、3 Hz – 13.2 GHz、3 Hz – 26.5 GHz 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。
