you really got balls! be careful with the new one.

I'm a bit new to DSOs, so pardon me if this is a naive question.  Should the trace on my DS1052E show "fuzz" on the top and bottom of the waveform when viewing the calibration square wave?  I would have thought the signal was well out of the noise and expected to see a rock solid display.

Hello, it would be awesome if you can do anything to help! Here is the information you requested:

PCB rev: 10 12
HW rev: DEMO7

>>Meiner

I bought them off ebay, I have yet to recieve them.

Yes, it is normal to see that, since the ADCs add some noise to the signal. (This, by the way, also applies to much more expensive Agilent or Tektronix DSOs.)
alm:
Indeed, and there's likely to be noise on the original signal (no signal in the real world has zero noise). Turning on averaging or bandwidth limiting should reduce it, and turning on peak detect should make it worse. As long as it's not too much (<= .1div or so, depending on bandwidth, acquisition mode and vertical sensitivity?), you shouldn't worry about it, and just get used to seeing it. I would be suspicious if I saw a completely clean signal. Using a shorter ground lead may help if you want to reduce it, Bob Pease has a good write-up about noise in scope shots.
