Key Features

4 independent PID controllers
PID Advisor (for adjustment of target bandwidth)
Auto Tune PID (for minimization of average PID error signal)
High-speed operation with up to 300 kHz loop filter bandwidth
Input parameters including demodulator data, auxiliary inputs, auxiliary outputs, and Arithmetic Unit

Phase unwrap for demodulator phase data (± 1024 π), e.g. for optical PLLs
Low-pass filter for derivative branch

Price

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.
