The MF-PID option consists of 4 configurable PID (proportional – integral – derivative) controllers. Seamlessly integrated with the MFLI 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.
