    HIGHLIGHTS

    • 4 個元件測試夾具 (DUT 尺寸:0.5 mm 到 20 mm)
    • 2 頻道內的獨立參數選項
    • 直接讀出電容率,磁導率 (選項)
    • 雙材質夾具 (工作溫度:攝氏 -55 度到 200 度)
    • 多功能分析 (溫度、Cole-Cole 圖、遲豫時間)
    • 掃描參數 (頻率、交流電平、直流偏壓、溫度)

    Keysight 4291B RF阻抗/材料分析儀為表面黏著元件和介電/磁性材料,提供了一個高準確度與容易量測的完整解決方案。有別於反射量測技術,Keysight 4291B採用的是直接電流-電壓量測技術,可在寬廣的阻抗範圍內提供更準確的阻抗量測結果。

    基本的阻抗準確度為+/- 0.8%。較高的Q準確度,有利於執行低損耗的元件分析。內部合成器可掃描1 MHz到1.8 GHz的頻率,解析度為1 mHz。1.8m長的正確接線可將分析儀連接到測試站,以便您將測試點延伸到分析儀之外,而不會影響到準確度。先進的校驗與錯誤補償功能,可消除夾具的量測錯誤因數,並確保DUT/MUT的高準確度與重複量測穩定度。

    Keysight 4291B還利用IBASIC程式化功能,來提供自動控制與監測測試信號位準的能力,元件可在定電壓或定電流下進行量測。使用直流偏壓選項(高達40 V和100 mA),即可量測與偏壓有關的阻抗特性。只要按一個鍵,內建的等效電路分析功能就會自動計算5種電路模型的電路常數。

    Keysight 4291B擁有兩個量測頻道,每個頻道都可被設定來量測單一(例如Z)或雙重(例如Z-theta)阻抗參數。彩色的TFT與分割顯示幕,可以同時顯示作用中的軌跡與記憶軌跡(儲存在RAM中)。內建的磁碟機可以LIF或MS-DOS格式來儲存程式與測試資料。您可以透過內建的IBASIC,直接從Keysight 4291B來控制外部測試儀器,例如溫度室或晶片探測器,而不必另外使用儀器控制器。

    材料的評估

    • Keysight 4291B可執行複雜的材料評估,並提高材料的評估品質與效率。Keysight 4291B為寬廣的頻率範圍(1 MHz到1 GHz),提供了一個完整的介電/磁性材料量測解決方案。
    • 基本準確度為+/-0.8%
    • 先進的校驗與錯誤補償
    • 四種元件測試夾具(DUT尺寸:0.5 mm到20 mm)
    • 2個頻道的獨立參數選擇
    • 介電常數、磁導率的直接讀值(選項)
    • 兩種材料夾具(操作溫度:-55℃到+200℃)
    • 多種分析(溫度、cole-cole圖、弛豫時間)
    • 掃描參數(頻率、交流位準、直流偏壓、溫度)
