Dewesoft allows outputting the signal also in the analyse mode. 

To use this option, first connect the device which has analog out option (BNC ports on the back or MULTI module). 

Make sure device is recognized by Dewesoft:

After the device is connected go to analyse and open the data file. On the top of the screen click the Analog out button and a pop-up window will appear. 

In the window you can see analog out channels (1-8). 

It is possible to assign one channel to each of the analog outputs.
