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.

Not exactly.

X-E range DSO's have no internal clock until the NTP feature was introduced to support the new Logging feature.
This requires a WAN connection to your local NTP server via LAN or WiFi when your local timezone is also required to be set.
R.J.:
It is exactly what I mean.
To take measurements and save them on a USB-stick, the date/time stamp is important.
Because now the OS's internal clock is never synced with the correct (NTP) time when the scope is switched on, the time of the file containing the measurements is not correct at all.
Especially when changing summer/winter time.
The issue is not whether the Operating Software clock should be exactly the same to the second or tenths of a second, it is about the internal OS clock being synchronised when turning on the scope so that the stored files are provided with the correct time and date stamp.
So exactly as it happens with the Siglent for logging measurements.
R.J.:
Here is an example of a multimeter from GW-Instek in which the internal clock can be synchronised over the LAN connection by using an NTP server on the Internet, as it should be.
When the local router is the NTP-server you can use the router address.
The pictures are a part of the manual for the GDM-906X benchtop multimeter.
On pages 139/140 of the manual show the settings.

So there are instruments that can sync their RTC by using NTP time servers.
Such an implementation is just a piece of software.

Duh. Nobody ever said otherwise.

Obviously. Nobody said a hardware RTC is the sole way to solve this problem.

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.

I’m puzzled as to why “router-as-NTP-server” occupies such a prominent place in your headspace, since that’s a comparatively rare configuration.
