Hi Amazing,
Many thanks for confirmation!
I also contacted with seller and he confirmed that this probes was supplied by Keysight.
I do not see any reason that this is counterfeit, but I can say:
Keysight want to much money when established price for that at $191
No way, probably
$19,10 will be enough.As for noise when you touch probe's body... Probably this is not seen at DSOX 2000/3000 series when probe's readout actuator connected to the scope contact, but my scope don't have this connection, that is because bad shield inside probe was very sensitive to noises. Don't know, probably another one "two months task" for Keysight probe's team.
