产品规格
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.
