They are much more than the 5370, but the single shot resolution is
only 200ps (HP5370: 20ps)

My best suggestion is to download the manual from the company formerly
known as HP and read it.

The main attraction in time-nut land is that they can do zero-deadtime
measurement series.

It's too bad they didn't build in a full ADEV(tau) plot function in
them (at least the 5372A doesn't have it).  I guess one could spend a
winter adding the code and burn a new set of eproms, but I've never
missed it that much.

Never attribute to malice what can adequately be explained by incompetence.
