DS1054Z front end switching noise?
« on: January 15, 2016, 11:11:33 pm »
So, I've got my Rigol DS1054Z a couple of days ago and hacked it to 100MHz.
As I was playing around with it, I discovered that the front end on all 4 channels seems to pick up a bit of noise.
I've disconnected all the probes and set coupling to GND and set 20MHz BW limit off.
it seems like channel 2 is "less" noisy that the others.
does anyone have this problem? ???

Its normal. The Rigol DS1054Z isn't perfect, but it was cheap...

It's extremely difficult to start life.. one features of nature.. physical laws are mathematical theory of great beauty... You may wonder Why? our knowledge shows that nature is so constructed. We simply have to accept it. One could describe the situation by saying that... (Paul Dirac)
