Noise Source

雜訊源 
10MHz-18GHz

 

提供 10 MHz 至 18 GHz 的寬廣頻率範圍,因此無需在不同頻段上使用多個雜訊源。 這款雜訊源的駐波比(SWR)很低,可顯著減少測試信號的反射,進而降低量測不確定性。 反射係數從 ON(開啟)到 OFF(關閉)的變化極小(<0.01),專為準確分析輸入阻抗敏感元件(如 GaAsFET 和許多 UHF 放大器)的特性而設計。

  • 頻率範圍:10 MHz 至 18 GHz
  • VSWR:< 1.3:1
  • 連接器:BNC(母頭)輸入偏壓/3.5 mm(公頭)
  • 低 SWR,可降低雜訊指數量測不確定性
  • 在特定頻率下單獨校驗 ENR 值


    Since it is broadband (10 MHz to 18 GHz), it eliminates the necessity for several sources at different frequency bands. The low SWR of the noise source minimizes reflection of test signals, reducing measurement uncertainty. The very small change in reflection coefficient (<0.01) from ON to OFF is designed especially for accurate characterization of input-impedance-sensitive devices (like GaAsFETs and many UHF amplifiers).

    • Frequency range: 10 MHz to 18 GHz
    • VSWR: < 1.3:1
    • Connectors: BNC (f) input bias / 3.5 mm (m)
    • Low SWR for reducing noise figure measurement uncertainty
    • Individually calibrated ENR values at specific frequencies
