Lock-in Amplifier

Available on Moku:Lab and Moku:Pro hardware

Key Features

Multiple demodulation modes
Select from internal and external (with or without phase-locked loop) demodulation modes, with the option to bypass the mixer stage.

Block diagram view
Easily configure, monitor, and adjust your setup at each stage in the signal processing chain.

Built-in probe points
The built-in oscilloscope and data logger are accessible via probe points. Tap any of these points in the block diagram to monitor signals and log data.

Integrated PID controller
Adjust proportional, integral, and derivative gain profiles in real-time.

Applications
• Pump probe/ ultrafast spectroscopy
• Laser scanning microscopy (SRS, TA, etc.)
• Magnet sensing (magneto-optical Kerr effect)
• Laser frequency stabilizing
