UHF-PID
簡介
UHF-PID 選配件包含4 通道可配置的PID(比例-積分-微分)控制器。基於大量的測量數據,這些控制器可以為許多儀器參數和輸出值提供快速反饋。可編程的PID 與鎖相放大器無縫整合,可應用到眾多領域,如用於兩個雷射器相位同步的PLL(鎖相環)設置、載波包絡偏移穩定和快速原子力顯微鏡模式。PID 智能設定可幫助快速找到合適的參數、顯示階躍響應和傳遞函數,支持複雜設置。通過自動調諧功能,迴路濾波器會自動調整以找到含有最小殘餘PID 誤差的點。

Introduction
The UHF-PID option consists of 4 configurable PID (proportional – integral – derivative) controllers. Seamlessly integrated with the UHFLI Lock-in Amplifier, the programmable PIDs feature in several applications including the setup of phase-locked loops (PLLs) for phase synchronization of two lasers, CEO stabilization, and fast AFM modes. The PID Advisor helps to identify suitable parameters, and displays step responses and transfer functions to support in-depth understanding of the experimental setup. Thanks to the Auto Tune feature, the loop filter settings are automatically adjusted to find the point with minimal residual PID error.
