The latest release introduces an upgraded multi-instrument mode with up to eight synchronized channels, a blended clocking architecture for superior stability, and expanded triggering and waveform controls.
Liquid Instruments has released MokuOS 4.0, the latest unified operating system for its suite of test and measurement hardware, introducing a redesigned interface, expanded instrument capabilities, and full support for the company’s new Moku:Delta device. The update is available for Moku:Pro, Moku:Go, and Moku:Lab users, and can be downloaded for free.
At the center of this release is a major upgrade to Multi-Instrument Mode. MokuOS 4.0 enables up to eight simultaneous instrument slots on the Moku:Delta, allowing researchers and engineers to replace entire racks of equipment with a single synchronized system. Users can also opt for three slots at full speed, unlocking high-performance multi-instrument test setups. Example applications include running three independent 2 GHz Lock-in Amplifiers, conducting time and frequency domain stimulus-response measurements, and generating optimized qubit drive and readout pulses across multiple channels.
Moku:Delta’s hardware enhancements are supported by a blended clocking architecture that merges the long-term stability of an oven-controlled crystal oscillator (OCXO) with the flexibility of a voltage-controlled crystal oscillator (VCXO). The key features are:
- Hybrid clocking delivers precision and responsiveness
- Supports external 10 MHz or 100 MHz references
- Optional GNSS module enables global synchronization
- Easy configuration via the updated interface
The update introduces improvements across the Moku ecosystem. Moku Cloud Compile 4.0 now offers a refreshed user experience and extends user-programmable development to Moku:Delta, while retaining legacy support for earlier firmware.Other instruments also see notable upgrades. The Moku Oscilloscope gains additional triggering options, and both the Waveform Generator and Arbitrary Waveform Generator now support manual triggering—enhancing waveform control for advanced applications, including quantum experiments. By combining a streamlined user experience with powerful new hardware and software features, MokuOS 4.0 positions itself as a comprehensive platform for researchers and engineers seeking scalable, flexible, and high-performance test systems.
