Abstract: This paper presents the structure and educational purposes of a laboratory system intended for the study of programmable waveform generators based on direct digital synthesis (DDS). The developed system consists of two basic functional blocks – a programmable waveform generator and a controllable high-frequency attenuator implemented on separate printed circuit boards. The programmable waveform generator is based on the EVAL-AD9833SDZ evaluation board, which is built around a monolithic low-power programmable waveform generator AD9833. The voltage controllable high-frequency (HF) attenuator is synthesized based on monolithic HF four-quadrant analog multiplier AD834 and transimpedance amplifier (TIA) based on current-feed¬back amplifier (CFA) AD844. The laboratory system is intended for the practical study of students in the Master’s degree program of “Electronics” at the Technical University of Sofia.
