This is my first DSO so I am not sure if my expectations are at fault or if it's my new oscilloscope. I really hope it's something I am doing wrong. I hooked each of my probes using the alligator ground clip to the compensation signal output terminals, clicked auto and I see a lot more noise on the signal than I expect.
However I get a very smooth signal when I use the ground spring instead.
I have tried all 4 channels with the same results. The calibration signal from my DHO804 looks smooth when viewing it from my 25MHz CRO using the alligator ground clip. However the calibration signal from my CRO looks even worse when viewed on my DHO804 with the alligator clip but clean using the ground spring.
I also tried taking the DHO804 to another room and it was no better viewing it's own calibration/compensation signal. I am nearly certain that AC circuit would be from the opposite phase as the one at my desk, certainly a different circuit down the the breaker.
I am using the ground lead provided by Rigol through my benchtop power supply. In the other room I loosely put it into the ground plug. I have also tested with the scope floating also with no difference.
What might I be doing wrong?
