Hi, last year I bought DSO PicoScope 2204 with integrated AWG. Two weeks ago I discovered that the AWG has problems in play the waveform that fall below values -0.5/0.6V. I attach pdf with images with the first 10 screens of the buffer. Note that not all records have the problem but just a few, but other times they all. Additionally, this problem occurs only a few days with limit -0.5/-0 .6V other days the limit is 1.5 -1, 6V and others-0.2V. Initially I thought it was a problem of power USB port, I tried using another Pc and nothing has changed. I reinstalled the drivers but still nothing. Suggestions?
