產品介紹
產品定位與應用Keysight / Agilent / HP E4428C Keysight E4428C ESG 類比訊號產生器 Analog Signal Generator 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 250 kHz to 3 GHz、250 kHz to 6 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。

原廠英文說明
Excellent all-inclusive RF and analog modulation performance up to 3 or 6 GHz The E4428C ESG analog signal generator delivers outstanding spectral purity, level accuracy, output power, and analog modulation performance up to 3 or 6 GHz for all general-purpose test needs. This makes the E4428C ESG a superb choice for general-purpose tests requiring CW, AM, ΦM, and FM receiver and component test signals in the cellular, ISM, and UNII frequency bands.Lowest Single-Sideband (SSB) phase noise performance in its price classSingle-Sideband (SSB) phase noise is an extremely important specification of a signal generator.For example, if used for measuring the adjacent channel selectivity of a receiver, your test results might indicate a failure when your receiver is actually functioning properly if the phase noise of the signal generator is too high.With a typical SSB phase noise performance of -134 dBc/Hz at 20 kHz offset from a 1 GHz carrier, the E4428C ESG will meet your demanding performance needs.Other key applications that require high spectral purity include LO substitution, low-jitter clock stimulus, blocking/interference signals, and in-channel measurements close to the carrier.
