Lock-in Amplifier

Enhance the sensitivity and accuracy of your measurements with the Moku Lock-in Amplifier. Offering up to 600 MHz bandwidth, excellent dynamic reserve, easy-to-use interface, and leading cost-per-channel in all classes, it’s the perfect blend of performance and convenience.

Elevate your research capabilities with an instrument that adapts to the evolving demands of cutting-edge scientific experiments.

Below is the Lock-in Amplifier’s user interface showcasing some of the key features explained below:

 

Key Features of the Lock-in Amplifier:

A versatile digital Lock-in Amplifier for demanding applications

With 600 MHz input bandwidth, >120 dB of dynamic reserve, and up to four input channels, the Moku Lock-in Amplifier offers unmatched performance and an industry-leading price per channel. A wealth of options for reference sources, filters, and PID control enable you to configure it to your specific experiment.

 

Dual-phase demodulation for enhanced measurement accuracy

The Moku Lock-in Amplifier features a dual-phase demodulator with cascaded, single-pole lowpass filters to attenuate the second harmonic and suppress noise in each quadrature. View the demodulated in-phase and quadrature signals prior to the lowpass filters using the integrated Oscilloscope.

 

Work more efficiently with included embedded instruments

Monitor up to four signals at a time using the Moku Lock-in Amplifier’s integrated four-channel, 1.25 GSa/s Oscilloscope, and continuously log data at up to 10 MSa/s using the built-in Data Logger. Additionally, the integrated PID Controller provides real-time control over gain profiles with configurable saturation.

 

Measure more, with a streamlined user interface

Wirelessly configure and monitor your setup’s performance with the intuitive software. Adjust all settings of the Moku Lock-in Amplifier and other instruments from your desktop, then move around the lab with Moku for iPad or Apple Vision Pro to easily adjust components and control instruments, fully untethered from your lab bench.

 

Integrate with your preferred software

Moku features API support for Python, MATLAB, and LabVIEW, allowing for straightforward integration of Moku with your existing technology stack.
