The Moku Lock-in Amplifier is easy to use and offers a range of advanced capabilities to optimize your experiment — at the most cost-effective price in the industry.
Key benefits
From a built-in Data Logger and Oscilloscope to the ability to deploy multiple lock-ins for deeper insights, you can expect more from the Moku Lock-in Amplifier.
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.
- Select between 6, 12, 18, and 24 dB / octave lowpass filter slopes
- Select between rectangular (X/Y) and polar (R/θ) coordinate modes
- View the demodulated in-phase and quadrature signals prior to the lowpass filters using the integrated Oscilloscope
Unlock greater insights with additional embedded instruments
Monitor up to four signals at a time using the Moku Lock-in Amplifier’s integrated 4-channel, 1.25 GSa/s Oscilloscope, and continuously log data at up to 10 MSa/s using its built-in Data Logger. Additionally, the integrated PID Controller provides real-time control over gain profiles with configurable saturation.
Internal and external references for maximum flexibility
Configure the local oscillator source to suit different applications. Select from internal or external demodulation references, or bypass the mixer stage altogether. Use the internal PLL frequency multiplier to demodulate up to the 250th harmonic or down to 0.125x of the fundamental frequency.
Measure more, instantly, from your preferred operating system
Wirelessly configure and monitor your setup’s performance from intuitive Moku software for iPad, Windows, or Mac applications. Moku software provides a clear and dynamic user experience so you can quickly configure, modify, and debug your setup.
Engineered to work seamlessly with your favorite APIs
API integration with MATLAB, LabVIEW, and more allows straightforward automation of your Moku device in complex setups or for repetitive tasks. Save your measurements, screenshots, traces, and other settings locally or to your preferred cloud app. You can also send work to yourself or colleagues within the Moku app.
Engineered for demanding applications
You can’t innovate for the future when your test equipment is stuck in the past. Use the Moku Lock-in Amplifier to accelerate development timelines with speed and flexibility unmatched by any other instrument in its class.
