Generic UDB1003S 3Mhz DDS Function Signal Generator Board

Introduction of the instrument
UDB100x(UDB100xS) 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, UDB100xS 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.
