Hi everyone. My first post here.
I work on CNC plasma cutting machines and occasionally face some difficult to diagnose faults. These faults often caused by EMI/RFI as a result of poor grounding or shielding.
I was wondering if an oscilloscope could be considered as a handy tool to diagnose these types of faults. If yes, what would be the minimum specs that you would recommend? A cheap USB oscilloscope, such as Hantek 6022BE or Owon VDS1022 suitable for this purpose?
My knowledge in electronics fairly limited and I don't think I will be needing these oscilloscopes for any other purpose.
I would appreciate any help to point me in the right direction. Thanks in advance.
