Having an issue with my new oscilloscope. It was picking up a LOT of HF interference from *somewhere*, and after some troubleshooting, I was able to track the interference down to my LED driver for my workbench lights. It is pumping a lot of HF into the air and into the mains, and I'm not too sure what to do about it. I bodged in a hand-wound common-mode suppression choke on both the mains and DC sides of the driver, Put a ferrite bead on the power cord at the plug, and ferrite beads on both the +ve and -ve wires right against the LEDs. The interference has lessened somewhat, but it's still buggering up the trigger on the scope. Any thoughts? First picture is with the driver plugged in, second picture is with the driver unplugged. The scope probe is not connected to anything at all.
