Oh but thats what the marketing blurb even says.
It hit me later that the thing that runs out is still the same CS oven

Here's some marketing eyewash for the thing... it has a 100 MHz output...

Darn it... I just bought a 5071A.

Did take a look at the various papers. The older Osciliquartz document does
overlap the new one. But the old one actually supplies more details. Good
reads.
It is interesting that the major consumable components like laser diodes
are all external. So what is the true life of the unit. Pretty curiou

If you look on the picture from wikipedia:

You can see the optical bench on top of the electronics rack.

Two year old deck with a fair amount of overlap,
Len Cutler was all set to build an optically
pumped Cs beam 20 years ago. Even then, he could get the lasers.
He was only missing one thing: money. HP management never
agreed to fund it. The paper conspicuously omits any spec
on absolute accuracy. The optical pumping does nothing to
improve th
Looks like Oscilloquartz is getting ready to sell this commercially!
Will give the 5071A a run for the money!
Reliability should go way up as:
-No electron multiplier
-No ionizer filament
-No state selection magnets
Also all the fiddley bits (laser diodes and photodetectors) are external
