MF-PID Quad PID/PLL Controller

Featured Product from Zurich Instruments


The MF-PID option consists of 4 configurable PID (proportional - integral - derivative) controllers. These controllers take a variety of different measurement data as the input quantity and they can provide fast feedback to a number of instrument parameters or analog output channels. Seamlessly integrated with the lock-in amplifier, the programmable PIDs enable operation in a wide range of applications such as the setup of phase-locked loops (PLLs) for the phase synchronization of two lasers, CEO stabilization and advanced AFM modes. The LabOne® PID Advisor helps to quickly find suitable parameters and displays step-responses and transfer functions to support in-depth understanding of the setup. During operation, the Auto-tune feature varies control parameters to minimize residual PID error.
