DS1054Z front end switching noise?
« on: January 16, 2016, 10:11:33 am »
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...
