產品介紹
產品定位與應用Keysight / Agilent / HP PD1538459502352 Agilent / HP 8903B Audio Analyzer 音頻分析儀
音頻失真分析儀 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 20 Hz to 100 kHz、20 Hz to 50 kHz、20 kHz to 100 kHz 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
The Agilent/HP 8903B audio analyzer provides unparalleled versatility and performance for audio measurements from 20 Hz to 100 kHz. The Agilent/HP 8903B combines the functionality of a low-distortion audio source, high-performance distortion analyzer, frequency counter, ac voltmeter, dc voltmeter, and SINAD meter into one compact package. With microprocessor control of source and analyzer, the Agilent/HP 8903B can perform stimulus-response measurements (such as signal-to-noise ratio and swept distortion) automatically with no additional equipment.
For ease of use, most measurements on the Agilent/HP 8903B are made with only one or two keystrokes. The Agilent/HP 8903B automatically tunes and autoranges for maximum accuracy and resolution. For quick identification of input signals, the analyzer counts and displays the input frequency in all ac measurement modes.
The standard Agilent/HP 8903B comes with 30 kHz and 80 kHz low-pass filters only. Two slots can accept any of the 6 optional filters Agilent/HP/Keysight 8903B Audio Analyzer 音頻分析儀
