1 OVERVIEW
MWG20 Is based on direct digital synthesis (DDS) signal generator, using the CPLD
design,easy to use, high signal stability. At the same time with TTL signal output, the
output signal to adjust the amplitude andDC offset, and the instrument has a sweep
function, were able to set the scanfrequency range and scan time. Suitable Laboratory
technicians and electronics enthusiasts to use.
