Multi-instrument Mode

Now available on Moku:Pro

Moku:Pro’s multi-instrument mode lets you run multiple, research-grade instruments at the same time and lets you connect these instruments to each other to build a customized test system.

Instruments incorporated

Run up to 4 instruments at the same time with 2 channels per instrument. Instruments get full, simultaneous access to all four analog inputs or internal inputs (1.25 GS/s 10 bit ADCs) and back panel triggering. Each instrument can drive the analog outputs to support a range of different scenarios for signal measurements, generation and real-time control.

Stand alone, run together

Instruments can run independently and be hot swapped out without disturbing adjacent instruments. Mix and match stand-alone instruments with tight synchronisation as all instruments share the same ultra-stable clock.

Instruments can join forces to build sophisticated, cooperative systems. Each instrument has high-bandwidth, low-latency communication lanes to other instruments. Instrument slots are connected by 2 real-time signal paths. Daisy chain instruments together to build sophisticated, digital signal processing pipelines.

How does it work?

Multi-instrument mode takes the Moku:Pro’s large UltraSCALE+ FPGA and breaks it up into five distinct regions, 4 for instruments and one for system control. Each region can be independently and dynamically reconfigured to implement its own bitstream. Areas of the FPGA outside these regions handle the routing of the analog inputs and outputs and include additional routing so that data can be exchanged between regions.

Example Use Cases

Multi-Frequency Lock-in Amplifier

Combine multiple Lock-in Amplifiers to provide multi-frequency and multi-harmonic demodulation.

Suggested instrument combination:
3x Lock-in Amplifier, Oscilloscope

Closed Loop Controller

Sub-μs input and output delay enables Moku:Pro to be used as a closed-loop controller even for high-speed applications. Make adjustments and see them reflected in real-time to the monitoring devices.

Suggested instrument combination:
PID Controller, Frequency Response Analyzer, Oscilloscope, Spectrum Analyzer

Generate and Control Complex Modulated Waveforms

Modulate signals with arbitrary waveforms and easily vary the modulations in real-time. Cascaded modulations are also possible. View, measure, and control your output waveforms simultaneously.

Suggested instrument combination:
Aribtrary Waveform Generator, 2x Waveform Generator, Oscilloscope

Power Analyzer - LDO/SMPS

Simplify testing and characterization of LDO/SMPS chips by using 2 Oscilloscopes for efficiency monitoring, the Frequency Response Analyzer for line-load regulation or PSRR testing, and the Spectrum Analyzer for output harmonic measurements.

Suggested instrument combination:
2x Oscilloscope, Frequency Response Analyzer, Spectrum Analzyer

Multi-instrument and Moku Cloud Compile unlock the ultimate in versatility

Multi-instrument mode is fully compatible with Moku Cloud Compile (MCC). MCC provides a hassle-free way for users to design, build and run their own algorithms on the FPGA. With multi-instrument and MCC together, users can combine their own creations with Moku:Pro’s built in instruments to aid debugging, save data and to give MCC creations a user interface.
