Description
The DG2000 series function/arbitrary waveform generator offers more capabilities at a value price. It features 40MHz bandwidth, arbitrary waveform, pulse generation and all the modulations to set up complex signals quickly and easily. The DG2000 series use direct digital-synthesis technology to create stable, accurate outputs on all waveform with low distortions. The frequency resolution is down to 1µHz, which makes DG2000 series produce high accurate Sine waves, very fast rise/fall square waves and well linear ramp waves.
Signal Regeneration The DG2000 series can be directly connected with the DS1000A series digital oscilloscopes. When connected via the built-in USB port of DS1000CA, the DG2000 series function/arbitrary waveform can regenerate recorded waveforms using data stored in the DS1000CA memory.
