At 100 mV/DIV, seems about right.

I think he means the spikes on the signal...

That looks like some sort of switching power interference to me, maybe a wall wart or a LED light. Try switching off everything in the room one thing at a time and see if it disappears.

Oh, yeah, see what you mean.  I thought he was referring to trace thickness due to wideband noise. 

Today, most of us are subjected to switcher noise.  I think you are correct.
