Waveform Generation Process
Direct Digital Synthesis (DDS) Mode
Direct digital synthesis (DDS) is a technique for deriving, under digital
control, an analog frequency source from a single reference clock
frequency. This technique provides high-frequency accuracy and
resolution, temperature stability, wideband tuning, and very fast and
phase-continuous frequency switching.
