Function Waveform Generator UNI-T UTG9020B - description: 

UNI-T UTG9020B function waveform generator adopts DDS technology which provides stable, high-precision, pure and low distortion sine signals. The excellent system features, user friendliness and versatile functions combination makes this arbitrary waveform / function generator a perfect solution for IC, serial bus and in-circuit function tests, simulation of sensors and natural environment signals. UNI-T UTG9020B dual channel arbitrary waveform / function generator has an intuitive user interface and simple front panel layout and instructions. Built-in AM, FM, PM and FSK modulating functions generate modulated waveforms without the assistance of a separate modulating source.
