Liquid Instruments SW-Pro-LIA Lock-in Amplifier

Overview

The Liquid Instruments SW-Pro-LIA is a digital lock-in amplifier module for the Moku:Pro series that enables precision measurement of weak signals obscured by noise. It supports dual-phase demodulation with more than 120 dB of dynamic reserve, demodulation frequencies from 1 mHz to 600 MHz, and features 4 input channels and 4 output channels with integrated oscilloscope and data logging capabilities.

Key Features

• Dual-phase demodulation (rectangular X/Y mode or polar R/θ mode)
• Demodulation frequency range: 1 mHz to 600 MHz
• Dynamic reserve greater than 120 dB
• 4 input channels, 4 output channels
• Built-in 4-channel oscilloscope (up to 1.25 GSa/s) and 10 MSa/s data logger
• Demodulation modes: internal, external, external PLL, and bypass
• Integrated PID controller
• API support: Python, MATLAB, LabVIEW

Applications

• Laser frequency stabilization
• Laser scanning microscopy
• Magnetic sensing (magneto-optical Kerr effect)
• Pump probe and ultrafast spectroscopy
