Spectrum Instrumentation has introduced a Direct Digital Synthesis (DDS) option for its 65xx series Arbitrary Waveform Generators (AWGs), extending DDS functionality across its full AWG portfolio to more than 70 product variants. In DDS mode, each channel can generate up to 16 individual sine-wave tones, with frequency, amplitude, and phase adjustable via simple commands, and parameter changes spaced as closely as 8 nanoseconds. The 65xx series supports output rates from 40 MS/s to 125 MS/s, 16-bit resolution, bandwidths up to 70 MHz, and scales from 1 to 80 fully synchronized channels. Instruments are available as PCIe cards or LXI Ethernet-controlled stand-alone units.
The DDS option adds frequency and amplitude slopes, flexible command sequencing, and real-time signal adaptation without large data transfers or complex waveform calculations. These capabilities address applications including network stimulation, filter and amplifier testing, vibration shaker control for mechanical resonance testing, and simulation of power fault conditions for circuit fault detection. Software support covers Windows and Linux, with programming interfaces for Python, MATLAB, C++, and LabVIEW, plus a no-code DDS CONTROL GUI for direct signal generation. All products include lifetime technical support from Spectrum Instrumentation’s engineering team and free software and firmware updates.
