Liquid Instruments SW-Lab-LIA Lock-in Amplifier Upgrade

Overview

The Liquid Instruments SW-Lab-LIA is a digital lock-in amplifier upgrade for the Moku:Lab platform, supporting dual-phase demodulation from DC to 200 MHz with more than 120 dB of dynamic reserve. The instrument integrates a 2-channel oscilloscope and data logger, enabling signal observation at up to 500 MSa/s and data acquisition at up to 1 MSa/s.

Key Features

• Dual-phase demodulation — select between rectangular (X/Y) or polar (R/θ) coordinates
• 1 mHz to 200 MHz demodulation frequency
• Dynamic reserve exceeding 120 dB
• Built-in PID controller with real-time gain configuration
• 2 input channels and 2 output channels
• 1 MSa/s data logger with probe points for monitoring
• Multiple demodulation modes: Internal, external, external PLL, and bypass
• API support: Python, MATLAB, LabVIEW

Applications

• Pump probe and ultrafast spectroscopy
• Laser scanning microscopy including SRS and transient absorption
• Magnetic sensing using magneto-optical Kerr effect
• Laser frequency stabilization and control
