Simplifying High-Speed Signal Generation

Generating many high-speed signals is hard and expensive. AWGs put up to 12 channels in one device, making setups easier and cutting costs.

If you are in the field of semiconductor testing, quantum computing, communications, medical imaging, or industrial electronics, you might face challenges generating multiple high-speed, synchronized signals. Using several single-channel waveform generators can be complex, take up valuable lab space, and increase costs. Spectrum Instrumentation’s DN6.63x Arbitrary Waveform Generators (AWGs) solve this problem by combining up to 12 synchronized channels in a single, easy-to-use unit, simplifying setups and reducing expenses.

These AWGs deliver ultra-low-noise signals from DC up to 2.5 GHz, with high precision thanks to 16-bit DACs. Each channel can operate in single-ended or differential mode and is synchronized via a precision PLL, making the system ideal for applications that demand multiple coherent signals, such as industrial testing, medical imaging, quantum experiments, semiconductor testing, and communications research.

Users can control the DN6.63x from any PC or network via Ethernet. Internal memory supports up to 48 Gigasamples with multiple replay modes, including Single-Shot, Loop, FIFO, Single Restart, and Multiple Replay. A DDS option allows one channel to output up to 64 sine waves, individually adjustable in frequency, amplitude, and phase, totaling 384 sine waves for complex signal generation.

Some of the technical features of the DN6.63x Arbitrary Waveform Generators include:

  • Up to 6 channels at 10 GS/s or 12 channels at 5 GS/s
  • Output up to 1 Vpp/4 dBm into 50 Ω or 2 Vpp into high impedance
  • Noise spectral density –150 dBm/Hz
  • SNR up to 64 dB
  • SFDR –90 dB
  • 10 new models added, bringing Netbox products to 47
  • Waveform speeds from 40 MS/s to 10 GS/s

Front-panel I/O connectors provide access to digital markers, triggers, PLL reference clock, and asynchronous I/O. An optional digital pulse generator enables independent programmable pulses. The AWGs are compatible with Windows and Linux and come with programming examples for Python, MATLAB, C++, and LabVIEW, as well as a high-level Python API. SBench 6 software allows intuitive waveform creation, analysis, and control, supporting standard signals, imported data, or file formats like ASCII, binary, and WAV.
