Based on Direct Digital Synthesized (DDS) technology and unique FPGA design SFG-2000/2100 Series Function Generators are built with exceptionally high performance far exceeding that of any conventional function generators at a very competitive price. Stable output frequency low distortion and fine frequency resolution are the most remarkable characteristics of this product series.
