数位合成函数信号产生器的详细介绍
Based
on Direct Digital Synthesized (DDS) technology and unique FPGA design,
SFG-2000/2100 Series
Fuon, and fine
frequency resolution are the most remarkable
characteristics of this product series.nction Generators are built with exceptionally
high performance far exceeding that of any conventional
function
generators, at a very competitive price. Stable output frequency, low
