Flexibility without compromise
Moku:Pro is the next generation of software-defined instrumentation, delivering both performance and flexibility. A powerful Xilinx Ultrascale+ FPGA is coupled with a high-bandwidth analogue front-end and robust networking and storage. Moku:Pro’s suite of software-defined instruments supports high-speed data acquisition, processing and visualisation, waveform generation, and real-time control applications. Proprietary hybrid front-end design performs frequency-dependent signal blending from multiple ADCs, delivering exceptional noise performance from acoustic to radio frequencies.

Moku:Pro is the most advanced system from the Moku suite of software defined instrument platforms. Harnessing the power of the FPGA combined with a high-quality analogue front-end, Moku:Pro is able to host multiple instruments on a single hardware platform without sacrificing specs or precision. This approach to test equipment makes it possible to scale and expand the scope of research easily. With Moku:Pro, researchers and engineers already have the right tool for the job.
In test and measurement, flexibility has typically demanded tradeoffs in performance. We overcome these tradeoffs by using signals from a 5 GSa/s, 10-bit ADC and a 10 MSa/s, 18-bit ADC in a patented blending scheme to deliver a low noise floor and high dynamic range from 10 Hz to 600 MHz. This is achieved through a digital crossover network consisting of balanced high- and low-pass filters that implement real-time blending of the dual ADC data streams.
Coming Soon: Multi-Instrument Capability
This autumn, users will be able to run multiple instruments simultaneously on a single Moku:Pro. You will be able to place instruments in up to four virtual “slots”,
dynamically adding or removing Moku:Pro instruments to any of the four slots. For example, you can add an oscilloscope to slot 1, a spectrum analyser to slot 2, deploy a PID controller in slot 3, all while maintaining phase continuity on a waveform generator running in slot 4. Each slot has dedicated access to the analogue inputs and outputs, allowing you to run an entire suite of instruments with just one device.
Instruments running in this mode can be chained together to instantly build sophisticated signal-processing pipelines. Instruments are connected by a low-latency, real-time 20 Gb/s signal path. Connections to the analogue inputs, analogue outputs, and adjacent instruments are run-time configurable for instant gratification. Your Moku:Pro is now even more powerful.

Coming Soon: FPGA access
Advanced users will be able to access Moku:Pro’s FPGA to implement custom digital signal processing by writing their own VHDL code. This cloud-based tool is accessed directly from a browser, allowing you to develop, compile and deploy custom algorithms to your Moku:Pro without a single software download.
Your custom instruments will have access to standard Moku:Pro resources, like analogue inputs and outputs. Custom instruments can also be deployed on individual instrument slots in multi-instrument mode. You can plug your creation into Liquid Instruments’ suite of instruments to provide a high-quality user interface and aid debugging. Programming and compiling are done with industry standard VHDL code, allowing you to work with high-level tools from third parties. Moku:Pro’s compiling tool provides an efficient, easy-to-use alternative to working with FPGA dev boards for early stage prototyping.

Input Voltage Noise
“Input voltage noise” describes the noise floor of the analogue inputs and is represented as an amplitude spectral density (magnitude of input voltage noise at different frequencies normalised to a 1 Hz bandwidth). It is impossible to resolve signal features below the noise floor. Input voltage noise is a key specification for a variety of instruments including lock-in amplifiers, spectrum analysers, and oscilloscopes as it can limit the signal-to-noise ration (SNR) in weak-signal applications.
Our FPGA algorithms automatically and intelligently blend the high-speed and low-speed signals from the 10-bit and 18-bit ADCs to optimise noise performance across the entire frequency range.
Rather than simply focusing on minimising overall noise, the filtering network is designed in a way that preserves a unity-gain frequency response for the signal.
In this figure, you can see the noise performance is quite low at 30 nV√Hz at 100 Hz and remains low across the entire frequency range.
