  1. Hi @attila, Thanks for the figure and the typons ! Your are right there is a problem with caching. I will test the voltage you mentioned during the next days. I have checked the output of the Audio on my scope, everything is ok. I think that the Feedback capacitor C163 may have been damaged causing the cut off frequency of the RC cell to have moved. I will check.
  2. Yeah, I know it is on me. But I usually do not give up easily. Here is my trouble shooting. I have managed to spot a short circuit on the output stage of the AWG1 caused by a fried op amp, i changed it and the consumption is now back to a std level (300mA), the board can now be connected to my laptop without power supply. The AWG1 generates a wave, but there are two problems. There is, as already mentioned, an offset and i can not correct it by calibration of the high gain AWG1. Also, the spectral behaviour changed : there is a loss in the generation of the wave, if i
  3. Hi, First, The Analog Discovery 2 is a very handy device and i am very pleased with all the functionality it offers. I got a problem with my device. The channel one of the wave form generator is not working any more. Here is the full the story. i mixed up the scopes for the signal generator and the oscilloscope and i ended up trying to measure a voltage of about 80v with the scope connected to waveform generator. As a result the device disconnected from my laptop. I noticed my mistake, unplugged the scope and tried to reconnect the device. It does show up in the list of available dev
