Using DDS direct digital synthesis technology to generate accurate, stable, low distortion output signal. CH1 and CH2 completely symmetrical two channels, each channel can be independently set the parameters. Supports user-defined wavesform, each arbitrary wavesform memory depth is 2048*12bits, 200MSa/s sampling rate. Can output arbitrary wavesforms and conventional function wavesforms(sine/triangle/square/sawtooth waves and TTL signal). All functions are digitally controlled, accuracy and stable.
