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. |
