Gigabit Streamer now available on Moku:Delta
The new Gigabit Streamer allows Moku:Delta users to transmit and receive data at speeds of up to 312.5 MSa/s through SFP and up to 5 GSa/s through QSFP. Deploy it in Multi-Instrument Mode alongside instruments such as the Phasemeter to continuously stream measurement data to your host PC. With the option to interleave data on up to two ports, the Gigabit Streamer excels in high-speed data recording and playback applications such as quantum key distribution and communications.

Configurable input bandwidth for Moku:Pro
In addition to the existing signal conditioning options on the Moku:Pro analog frontend, users now have the ability to switch the frequency of the input lowpass filter between 300 and 600 MHz. This allows users working at frequencies below 300 MHz to reduce the effects from higher frequency noise. This change also increases the range of Phasemeter and Spectrum Analyzer from their previous 300 MHz, with both instruments now measuring frequencies up to 600 MHz. You can find this option alongside other Input options (in single instrument mode), or by clicking on the input port number (in Multi-Instrument Mode).

New instruments and features for Moku:Lab and Moku:Go
Last year, the Moku Neural Network was released for Moku:Pro. Now available on Moku:Go and Moku:Lab, users can deploy networks of up to five hidden layers of 80 neurons each, with the choice of five activation functions. To learn more about Neural Networks and their uses in test and measurement, read the blog post on the topic. To get started using the Neural Network on your Lab or Go, read the step-by-step tutorial on building, training, and deploying small-scale networks.
Moreover, Moku:Go and Moku:Lab now also feature an optional 3-slot Multi-Instrument Mode, selectable in the top left corner of the configuration screen. Users can select between 2-slot Multi-Instrument Mode for the maximum sampling rate, or 3-slot mode for more flexibility.
Measure correlation functions with Moku Time & Frequency Analyzer
One of the most requested features for the Moku Time & Frequency Analyzer is the ability to calculate the second-order correlation function g(2)(t) on the fly. This function provides information about the “quantumness” of a light source and is a figure of interest for a variety of quantum optics applications. When plotting event intervals, users can now switch from a histogram of the measured time intervals to the g(2)(t) correlation function, which updates in real time. This enables rapid measurement of correlations between events, and the information can be saved and transferred to your PC for further analysis.
For other types of time interval measurements, users can now specify how the Time & Frequency Analyzer handles multiple starts, using either the first or the last “start” event before a stop event is detected. Find this option under the “Advanced” tab on the configuration screen.

Faster custom code and local compiling
Moku Cloud Compile has become Moku Custom Instrument, accompanied by several new features. While the web-based compiler remains an option for all users wishing to implement custom HDL code, Custom Instrument now has the option for an on-premise compiler. Using local compile, users can access higher clock speeds, enabling Custom Instrument modules to operate at the full sampling speed of their Moku device*.
In addition, current users of Moku Custom Instrument will find that they can now read data back from their custom bitstreams through the status registers, and can also search for bitstreams through an in-app browser.
For Custom Instrument configuration and pricing info, [see here]. To get started writing custom HDL code, read the application note on the topic.
*Subject to export control and restrictions on Moku:Pro and Moku:Delta.
