In that case it's unlikely the DSO138 is the problem. Check a signal from a different source. Thank you for the response. I checked the signal with another oscilloscope connected in parallel. The signal is fine. Also, I tried different signals and the problem persists. The distortion is 2 divisions...

Hello, I completed assembly of my DSO138. It works fine, but with one exception. When I supply a sine wave to the input, and its amplitude is larger than 4 divisions at the x1 amplification (or 2 divisions at the x2 amplification, or ~1 division at the x5 amplification), the trace shape is distorted...
