Introduction of the instrument
UDB11xx(UDB11xxS) series direct digital synthesis signal generator use DDS technology and FPGA design with the characters of high stability and low distortion ect., with the function of TTL output and 60MHz frequency meter, SG100xS series have sweep function, the start and end frequency and sweep time can be set at will. It's the ideal equipment of electronic engineer, laboratory, production lines, the teaching and scientific research.
