Zurich Instruments HF2LI 是一款高頻雙通道鎖相放大器，採用最新硬體和軟體技術，提供行業領先的規格和功能。120 dB 動態儲量設定了 50 MHz 頻率範圍的基準。在很多應用中，一台 HF2LI 即可代替多種傳統儀器。
基本儀器功能可通過以下升級選件進行擴展：
- HF2LI-MF 多頻選件
- HF2LI-PID 四通道 PID 控制器
- HF2LI-PLL 雙鎖相環
- HF2LI-MOD AM/FM 調製
這些選件均可現場升級。對於電流測量，我們提供 HF2TA 電流放大器作為有源探頭，它可以放置於靠近裝置的位置，實現 4 探頭測量等測量。
應用：
- 感測與驅動：MEMS 陀螺儀、加速度計
- 微流控
- 非線性成像：CARS、SRS、太赫茲等。
- 雷射光譜
- 原子力顯微鏡（AFM）、掃描探針顯微鏡（SPM）
- 非破壞性測試
- 醫療技術
