High-Speed Multi-Tone DDS Generators: 50 Tones per Channel

The latest DDS generators have introduced a groundbreaking feature that allows for up to 50 sine wave carriers to be generated on a single output channel. This advancement opens up new possibilities for engineers and scientists to produce and independently control multi-tone sine signals. DDS, or Direct Digital Synthesis, is a powerful technique known for generating high-purity signals, typically sinewave cores, with ultrafast switching between output frequencies and fine frequency resolution.

The 96xxs series of DDS generators offers a range of models in different form factors, including PCIe cards, PXIe modules, and Ethernet instruments. A single PCIe or PXIe card can generate up to 50 low-phase-noise variable-frequency tones across up to 4 channels, while the stand-alone Ethernet instruments provide from 2 to 24 channels. For applications requiring more than 50 tones, the larger NETBOX units can support up to 300 tones, or multiple cards can be connected together with the Star Hub synchronization module to create systems with up to 400 tones.

These DDS generators are fully programmable, allowing for instant changes to be made using simple commands. Users can adjust settings such as frequency, amplitude, phase, amplitude slopes, and frequency slopes during runtime or via preloaded sequences of commands. With millions of DDS commands that can be stored in the on-board memory, setting changes can be triggered externally, by an internal timer, or immediately on command, all without any transition jitter or glitches.

The versatility of the 96xx series DDS generators extends to a wide range of applications in various industries, including industrial, medical, imaging systems, network analysis, and communication technology. These generators are particularly useful for controlling lasers through AODs and AOMs in quantum experiments, enabling high-speed laser control with just a few simple commands. Additionally, the generators can be converted into fully functional Arbitrary Waveform Generators (AWGs) for more complex waveform generation.

Operating under Windows or Linux systems, the 96xx series DDS generators can be easily programmed using examples for C++, Python, C#, JAVA, LabVIEW, MATLAB, and other languages. The high-level Python APIs provided offer a user-friendly way to control the products and customize signal generation according to specific requirements.
