產品介紹
產品定位與應用Keysight / Agilent / HP PD1527822662021 Agilent 8751A 向量網路分析儀 Vector Network Analyzer
VNA 屬於向量網路分析與射頻微波元件量測設備，適合用於S 參數、回波損耗、增益／損耗、VSWR、相位、群延遲、濾波器、放大器、天線、線纜與 RF 模組驗證等情境。
既有資料中可辨識到 5 Hz to 500 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、埠數、動態範圍、校正件、測試治具、Bias Tee、衰減器與其他選配功能，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 HP 8751A network analyzer is a high-throughput instrument with lab precision that covers 5 Hz to 500 MHz. The HP 8751A provides resolution of 0.001 Hz, 0.001 dB, 0.001 degree, and 10 ps for characterizing the linear behavior of either passive or active networks, devices, or components in the lab and the production test areas. The built-in 1.44 MB disk drive is for direct save/recall of instrument state, calibration data, and application programs for your customization.Dedicated 50/75 ΩS-parameter test sets, 50/75 ΩT/R test kits, and the 1 M Ω input adapters are all available.
