Moku:Delta

Moku:Delta is a versatile, high-performance software-defined test and measurement platform, purpose-built for precision, flexibility, and real-time performance. It features eight 2 GHz 14-bit and 20-bit analog inputs, eight 2 GHz 14-bit analog outputs, and 32 bidirectional digital I/O channels. Powered by a Xilinx® UltraScale+™ RFSoC FPGA, Moku:Delta supports integrated signal processing, control, analysis, and waveform synthesis in a single cohesive platform. A +1 ppb ultra-stable onboard reference clock and advanced timing options, including 10 MHz, 100 MHz, and GPS-disciplined references, ensure accurate synchronization. Moku:Delta enables engineers and scientists to develop test systems that combine high-performance instrumentation with user-defined, hardware-accelerated algorithms.

Deploy up to eight instruments simultaneously

Multi-Instrument Mode on Moku:Delta runs up to eight instruments simultaneously, so you can create custom test sequences and complex measurement workflows. Each instrument has full access to all analog inputs, outputs, and adjacent instrument slots. A low-latency, real-time 30 Gb/s signal path connects the slots, enabling independent operation or tightly integrated signal processing pipelines. Swap instruments in and out dynamically as needed, or deploy your own custom algorithms using Moku Cloud Compile for advanced, application-specific functionality.

2 GHz Lock-in Amplifier

The Moku:Delta digital Lock-in Amplifier performs dual-phase demodulation (X/Y or R/θ) from DC up to 2 GHz, with over 120 dB of dynamic reserve. Demodulate using the onboard Waveform Generator or phase-lock to an external reference at the fundamental, harmonic, or subharmonic. Blended ADC technology delivers a consistently low noise floor across the full 2 GHz input bandwidth. Built-in probe points make it easy to monitor and log signals at key stages of processing. A built-in PID Controller supports closed-loop control and phase-locked loop applications.

Built for quantum control

Moku:Delta provides a powerful, unified platform for advanced quantum experiments, combining essential tools in a single hardware system. It enables laser frequency stabilization with the Laser Lock Box, high-fidelity waveform generation using a 2 GHz Arbitrary Waveform Generator, and parallel demodulation with up to eight Lock-in Amplifiers. The Time & Frequency Analyzer supports zero-dead time photon counting and event timing. All instruments run on a shared, timing-stable, synchronized FPGA, delivering low-latency feedback, exceptional signal integrity, and seamless integration for complex quantum control workflows.
