Output Amplifiers
This arbitrary waveform generator board uses separate output am-
plifiers for each channel. This gives you the possibility to seperately
set up the channel outputs to best suit your application

Output offset
In many applications an output of symmetrical sig-
nals is required. But in some cases, depending on
your application, it can be necessary to generate
signals that are not symmetrical.
