the instrument

instrument

This 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 researc h.
