The 4047 B's dual architecture offers all the benefits of a combined DDS and a true point-by-point arbitrary waveform generator (AWG), minus the limitations of either technology. The DDS chip produces standard sine and triangle waveforms with high-frequency resolution. The true point-by-point AWG implementation improves signal integrity for arbitrary waveforms by producing significantly less jitter and distortion than a DDS-based architecture. Custom arbitrary waveform generation is accomplished with a variable clock signal to reproduce each point stored in memory without skipping or repeating data points.
The 4047B is designed to integrate with B&K Precision's waveform editing software WaveXpress easily. This allows users to generate complex arbitrary waveforms that can be output via the instrument's 14-bit, 125 MSa/s, 16kpts arbitrary waveform generator.
