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

The output amplifiers can easily be set by the corresponding am-

plitude registers.

The table below shows the available registers to set up the output

amplitude for your type of board.

The amplitude can be changed at any time even if the board is running and outputting a signal to the con-

nectors. The board will not be stopped when changing these settings.

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.

For such cases you can adjust the offset of the out-

puts for each channel seperately.

The figure at the right shows some examples, how

to set up the offset in combination with different am-

plitudes.

The offset settings can be changed at any time even if the board is running and outputting a signal to the

connectors. The board will not be stopped when changing these settings.
