Out of curiosity, I wanted to check the output of of new portable generator. I have a meter than reads VAC and kHz. The house reading was 124.6VAC and 60-61Hz. The generator was 120.9-121.1VAC but the frequency was reading 180-200Hz. It is not an inverter style, so (the thinking is) there should not be much in the way of "digital" effects and harmonics for the meter to lock on to, but it still may be a possibility. I would like to check it with a scope. My father has a VERY old scope that I should be to borrow. If the scope is plugged in to the house/utility supply, can I place the probe ground on the AC neutral and the probe tip on AC Line (or hot) and see the power waveform? I don't often try to look at the incoming power as a signal. I did once up on a time and ran into some issues, but don't recall what the issue was.
