The problem with sampling 'scopes is that you cannot get a continuos

Does that matter for phase noise measurements? Doesn't that just make
the measurement take correspondingly more time?
It matters a lot, since the length of memory will limit the how close in
you can do it. You can naturally make multiple runs, and that's what the
TimePod do, but with decimations done in realtime by the firmware.
You can do it with high speed ADCs, but it won't bee cost efficient and
it will cost you in speed, as you need to do much in software processing
to get there.
The TimePod is in that context a fairly well balanced design as in bang
for the buck. Another aspect I like is that it can do pretty neat
long-term measurements.
