Interference or something wrong with my scope?
« on: April 04, 2017, 11:02:42 pm »
I'm getting these weird peaks every 5 to 10 seconds when the scope is idle, probe connected. Same with every channel. Any idea what might be causing this? I think I have removed anything that might cause an interference. Scope is a Rigol 1054z.

Well, if the the spikes go away when you disconnect the probe, then the scope is fine. Disconnect the probe and see what happens then.

A mobile phone charger plugged in somewhere?

.  That took much longer than I thought it would.

Thanks a lot, case closed! Didn't see the spikes when probes were disconnected. When I started looking under the table for my charger I realized I had my power line ethernet repeater connected and it had it's wifi-extender enabled...  :palm: disconnected it, problem solved. Thanks again.
