So this is what I want to see in the R&S RTB200x....... :o When powering the scope, it's syncs the internel clock. That's all.

No, it’s not syncing with the router, it’s syncing with whatever NTP server you tell it to. Most of the time that will NOT be your local router.

It depends a bit on how the network is setup. DHCP has a field that can tell a client which NTP server to use so routers can use that to announce NTP servers to clients. For example: the internet router that is supplied by my internet provider comes pre-configured with NTP servers and it likely includes the NTP servers' information as part of the DHCP fields it supplies to clients. In other words, it is not outlandish to think that an internet router can play a role in a plug&play NTP configuration of devices on the network.

Sure, but that’s still not the same thing as the router being the NTP server.

R.J.:
I mentioned it before, see reply #14 in this topic.

Yes the router acts as a NTP-server and every router has de ability to do so!All the network clients can use the routers IP-address as the NTP-server, your IOT-devices, laptops etc....The router can be used if the ability is in the client to synchronise with an ntp server.

Furthermore, time-synchronisation is essential within a network.
After all, all servers and clients must have the same time, as otherwise logging on within the network is not possible with a large time difference between clients and servers.
Also, if there is no time synchronisation, the various internal clocks of clients will always be out of sync and the content of events in log files will be meaningless.

Your router has that option, but most do NOT. As I said, that’s a rare configuration, generally speaking.
