An inverter would convert to DC and back again to AC, thereby being able to convert 50 to 60 hz. This looks to be a real step up/down transformer. I'd plug the whole thing into an isolation transformer and then put a scope on the output. I can't imagine that a real transformer could have a distorted output unless you were over-taxing it. Then it might saturate and clip.
