Autel Scope

Just picked up a MP408 brand new for $200. I brought it to work to check the accuracy against a sourcing signal from my Fluke. This was at 5v and 20Hz and 20kHz which Autel says is the high end. I didn’t get to zooming into waveforms or anything as I haven’t really played with it much yet. Was just curious about the accuracy at the low end, high end and voltages. Thought I would share the results. This was obviously a square wave. Sine wave results were the same as far as accuracy.
