產品介紹
產品定位與應用Keysight / Agilent / HP PD1534239103400 Agilent 8496H Programmable Step Attenuator 可程式控制階梯式射頻衰減器
RF Programmable Step Attenuator 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。
實際量測範圍與選配需依機身配置、附件與校正狀態確認。
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 8494/95/96/97 family of step attenuators offer fast, precise signal level control in three frequency ranges, dc to 4 GHz , dc to 18 GHz and dc to 26.5 GHz They feature exceptional repeatability and reliability in a wide range of frequency, attenuation and connector options. Precision plated leaf-spring contacts remove attenuator sections (miniature tantalum nitride thin-film T-pads on sapphire and alumina substrates) from the signal path.
Unique process controls and material selection ensure unmatched life and contact repeatability. Miniature drive solenoids in the programmable models keep switching time, including settling, down to less than 20 milliseconds. Once switched, strong permanent magnets hold the solenoids (and attenuation value) in place.
Current interrupts automatically disconnect solenoid current, simplifying driver circuit design and minimizing heat dissipation. Programming is done through a 12 -pin Viking socket or optional ribbon cables with DIP plugs.
