As the world becomes more connected by global communications networks, the field of free-space optical communications has grown as an alternative to traditional data transmission via RF frequencies. While optical communications setups deliver scalability and security advantages along with a smaller infrastructure footprint, they also bring distinct challenges, including attenuation, interference, and beam divergence.

During this presentation, Liquid Instruments will give an overview of the FPGA-based Moku platform, a reconfigurable suite of test and measurement instruments that provide a flexible and efficient approach to optical communications development. You’ll learn how to use the Moku Lock-in Amplifier and Time & Frequency Analyzer for both coherent and direct detection of optical signals, as well as how to frequency-stabilize lasers with the Laser Lock Box.

You’ll also see how to deploy these instruments simultaneously in Multi-instrument Mode for maximum versatility, plus digital and analog modulation methods such as phase-shift keying (PSK) and pulse-position modulation (PPM) covered in a live demo.

A Q&A session will follow the demonstration.
