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
Compact footprint
Combine four instruments at once in Multi-instrument Mode for ultimate efficiency in a space-constrained lab.
Real-time plant control
Visualize your signal configuration
Design your control system's frequency response in real time using the interactive Bode plot, embedded within the Moku PID Controller. Customize proportional (P), integral (I), differential (D), double-integral (I+), integral saturation (IS), and differential saturation (DS) gain profiles. Download the software for free to explore demo mode.
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
