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,
