I'm curious. When you buy a licence key from Rigol (or a distributor) you just provide them with your serial number, right? Does Rigol also know the private key of every scope, or is it just different for the MSO series? |

Yes, all they need is the serial number of the device. |

Or maybe the private key is simply derived in some way from the serial number (using a private Rigol key). Does anybody know how the dealers generate the keys? I think Rigol doesn't generate them directly so the dealers must have software to generate keys. Do they have to go to a special Rigol website or something? Anybody know? |

The most important fact , the generated key is NOT identical from the one generated by riglol. ;) |
