Dirty Electric
How would I know or test if a generator was putting out the wrong frequency or "dirty" electricity? (recently changed oil, new plug, new air filter, cleaned out carburetor best I could... wondering...

I use the transformer for isolation as well. I just wanted readers to be aware another component would be required.
$50 says you are wrong.
120V RMS is about 170V pk so you would expect to measure 17V pk using this transformer. 60Hz would be 16.66 mS pk to pk.
That was a quick "sample" of what is available now days, there ARE other portable versions out there that can easily handle higher input voltages.. You simply have to do some looking.
There also versions that have no readout, instead they can connect to a laptop or even a Tablet. and have many advanced features of storing and playing back the waveform.
And, in reality, with 60hz, you do not need a large bandwidth on the scope, most any scope will work even as low as 100 Khz will show noise spikes and if the waveform is badly distorted.
