Btw, what does 40V mean here?
40Vpp or 40Vrms?
That's quite a difference.
Thanks.

That's a good question

RMS is meaningless without knowing the waveform. For example, the peak to peak of a 100v rms rectangular wave with 5% duty cycle is vastly more than the peak to peak of a 100v rms square wave (50% duty cycle).
Only peak voltage is a definitive spec.

Hmm, but that would be strange, since 230V mains is in Vrms.
So that would only be about 14Vrms (sine) or 140Vrms at 10x?
My Hantek explicitly states the maximum values in Vrms in the manual:

Never equate to stupidity that which can adequately be explained by laziness and ignorance.

maybe laziness but I'm not interested in connecting this to 235V AC and find out it will blow at my face. 220V AC is not used anymore in my country it's 235V AC and some times at night 240V AC
