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.
