Noise on AD2 with scope leads shorted

[Cold Fusion]

I recently purchased the Analog Discovery 2 USB scope and am dismayed by the noise on the screen. Even with the scope probe ground clip connected to the probe tip there is 20mVpp 60Hz noise present.

Hello,

I did not see an input noise specification in the Analog Discovery 2 (AD2) Resource Center (reference page). However, when I do a similar test with the BNC adapter board and a scope probe (DC coupling), my results are 10 - 12 mVpp. This equates to roughly 4 counts of p-p noise where each count is 3mV.  An FFT of the signal did not show a significant 60 Hz noise component however, if the probe is switched to 10x, then a 60 Hz component did appeared. 

regards...

Hi @Cold Fusion,

I presume you are using the BNC Adapter with the Analog Discovery 2 based on your description?
