I have the Analog Discovery 2 and the bnc board with scope probes. But I have problem with the 10X settings on the probes. The problem is that I get a little dc offset with the osciloscope and the built in functiongenerator. When I apply a sinus signal with an amplitude of 1 V, then I measure about 0,8 - 0,9 V positive voltage and negative 1,1 - 1,2 V, which means that there is a dc offset. The dc and ac coupling does not help. There is no problem with the 1X setting on the probes. I have compensated the probes on the 10X setting with a 1 KHz squarewave which have an amplitude on 1 V. What could be wrong? (: When I apply a dc signal with the functiongenerator, then I measure - 0,1 V on the osciloscope on 10X setting.
