² Waveforms were generated using DDS (Direct Digital Synthesis) with a waveform table size of 2048 samples and a phase accumulator of 32 bits. Long, non-repetitive, waveforms such as modulated or DDS (Direct Digital Synthesis)- based signals offer better spurious performance.

For periodic waveforms represented by a small number of unique samples, DAC nonlinearities limit dynamic specifications. SFDR performance may be worse at signal frequencies near to integer submultiples of the sampling frequency due to harmonic stacking on images (ex. Fs/N with N=8,16,32).
