Performance and versatility to advance discovery

The Moku:Pro PID Controller integrates crucial functionality for open- and closed-loop tuning while also working alongside additional instruments for advanced applications. Combine Lock-in Amplifiers, Digital Filter Boxes, and more to create a fully contained lab in a single device.

Low latency

Utilize up to four fully configurable PID controllers with sub-microsecond latency for applications such as laser and phase stabilization.

Compact footprint

Combine four instruments at once in Multi-instrument Mode for ultimate efficiency in a space-constrained lab.

Real-time plant control

Customize nearly every step in the signal processing chain. Upgrade from DIY solutions and limiting simulation environments for enhanced research.

Applications

With Moku:Pro, you have access to multiple pieces of advanced control systems instrumentation in one device. Deployed standalone, in Multi-instrument Mode, or embedded in other instruments like the Laser Lock Box, the PID Controller covers applications such as:

• Feedback and control systems design
• Laser frequency stabilization
• Pressure, force, flow rate, and other controls
• Scan heads/sample stage positioning
• Temperature regulation
