I wrote about the recent signal generator purchase. The unit has a known problem, the earth is floating and the DC side "ground" reference is coupled from the AC side via a capacitor. If you happen to touch the reference points on the probe BNC connectors, you get an electric shock! About 100V ac on those points..

So, I bought a 3-pronged AC female connector and filed the cabinet a bit and fitted it and wired the common to the proper earth. A proper fix would be to replace the power supply itself. Feeltech says they are replacing the powersupply soon..
