The SK433 PI2D Compensator was primary designed for use in laser control applications involving high-speed servo loops. Low-noise and wide bandwidth closed-loop performances are achieved through a low-noise front-end differential amplifier followed by a programmable PI2D compensator. The SK433 also includes an auxiliary integrator which can be used for preventing the saturation of the high-speed primary loop. Indeed, by using this integrator within an secondary servo loop, the PI2D’s output signal can be automatically de-trended.
Like all modular instruments of the SK-Series, the SK433 PI2D Compensator can be operated stand-alone or within a platform where several modules can be assembled to configure a specific control or measurement system. For example, the SK433 can be coupled to the SK301 RF Demodulator for high-performance, closed-loop laser frequency control.
