Has it got an external input? I've got an ancient (or is that well-aged
and "even more stable"?) GenRad OXCO which I can plug into any generator
or counter that will take an external reference to make it more accurate.
With your rather more serious (than mine) operations, I'd think you
could put in one rubidium or cesium reference (and or some new-ish
method tied to GPS I'm not overly familiar with) and distribute it
throughout your labs/plant/wherever, so long as your counters and/or
generators will take an external reference frequency. Assuming decent
cable termination and appropriate drivers, I don't see that you'd need
more than one "really good" reference.
We have an SRS SC-cut ovenized oscillator, that we mounted in a rack
box with a power supply. Ditto an ebay rubidium. We even have an old
HP cesium standard, which is a big deal to fire up, so we seldom use
it. All three typically agree to something like 30 ppb.
Cool: trigger a scope from the cesium and look at the rising edge of
the rubidium, at 10 ns/cm. Ten minutes later, it's barely moved.
But still, a grand for a TCXO is insane. It probably costs them 20
bucks or so. So, no Agilent counter.
