Multi-instrument Mode

Test smarter and maximize flexibility with Multi-instrument Mode for Moku devices by running up to four instruments simultaneously to create custom test sequences.

Connect multiple software-defined instruments to build powerful signal processing pipelines with the ability to dynamically swap instruments on the fly — and monitor the performance of each instrument in its own dedicated window for a true bird’s-eye view of your experiment.

Real-world applications

Multi-frequency Lock-in Amplifier

Perform multi-frequency demodulation with up to four Lock-in Amplifiers running on one device. Each Lock-in Amplifier can demodulate the signal at the fundamental, higher harmonics, or frequency divisions using an internal or external reference signal. Suggested instrument combination: 3x Lock-in Amplifier, Oscilloscope.

Closed-loop controller

Configure your Moku device as a closed-loop controller for high-speed applications, thanks to sub-µs input and output delays. Make adjustments and see them reflected in real time. Suggested instrument combination: PID Controller, Frequency Response Analyzer, Oscilloscope, Spectrum Analyzer.

Generate and control complex modulated waveforms

Modulate signals with arbitrary waveforms and seamlessly vary the modulations in real time. View, measure, and control your output waveforms simultaneously. Suggested instrument combination: Arbitrary Waveform Generator, 2x Waveform Generator, Oscilloscope.

Power analyzer for LDO/SMPS applications

Simplify testing and characterization of low-dropout linear regulator (LDO) and switch-mode power supply (SMPS) chips with a test system including two Oscilloscopes for efficiency monitoring, the Frequency Response Analyzer for line-load regulation or power supply rejection ratio (PSRR) testing, and the Spectrum Analyzer for output harmonic measurements. Suggested instrument combination: 2x Oscilloscope, Frequency Response Analyzer, Spectrum Analyzer.

Advanced capabilities, simple workflow

Create a customized test system on a single piece of hardware

With partial FPGA reconfiguration, Multi-instrument Mode enables you to build custom test configurations with low-latency, lossless interconnects to reduce complex cabling and impairments.

Daisy-chain instruments together to build sophisticated digital signal processing pipelines and hot-swap instruments in and out without interrupting those running in tandem.

FAQ

How does Multi-instrument Mode work?

Multi-instrument Mode allows you to run up to four software-defined test instruments simultaneously, with full access to the platform’s analog front end, internal inputs, and back panel triggering. It's easy to select the instruments you want to incorporate in your setup directly from the Multi-instrument Mode interface on the Moku: app.
What hardware platforms is Multi-instrument Mode compatible with?

Multi-instrument Mode is available on all Moku devices: Moku:Pro, Moku:Lab, and Moku:Go.
How many instruments can I run at the same time?

You can deploy up to four software-defined instruments simultaneously in Multi-instrument Mode for Moku:Pro. For Moku:Lab and Moku:Go, you can deploy two instruments in tandem.
What software do I need to run Multi-instrument Mode?

For maximum flexibility, you can configure Multi-instrument Mode directly on the Moku: app for iPad or desktop. Download a free demo of the app here.
Can I run custom instruments in Multi-instrument Mode?

MWith Moku Cloud Compile, you can deploy custom VHDL code directly into one of the instrument slots in Multi-instrument Mode and run their algorithms alongside the built-in instruments for debugging, data sharing, and more. If you need help writing the code, simply ask ChatGPT to help you get started.
