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.
