Most people don't know that units like the Efratom FRK FM the laser to
keep it on frequency in a simple control loop and this can cause issues
depending on your use case. The other thing that most don't realize is
their is a difference between stability and accuracy. You'd ideally like
both to
I think the most important thing to remember in the Rb vs GPSDO
debate is that without some other standard like a GPSDO or better to
compare to or calibrate against, you never know that your Rb
oscillator is actually on-freq. The LPRO-101 has an adjustment to
vary its freq. How would I know
A while back, over on the evil empire, they were selling both the
GPSDO and
RbO that were scrapped out of Agilent systems. The didn't have the inter-
connect cables, but they were easy to make.
I bought one just to experiment with, but quickly decided that for my
needs, the
GPSDO was all I
Not dried up. $75 or so on evilBay now.

My apologies, old age got me again ... it was Lucent not Agilent.

Just type in rubidium and you'll get more hits than you wanted.

Guys, remember what it said under Brian's picture in his senior yearbook:
Pick a side and I'll argue with you.

I guess it depends on what you mean. The average Rb reference oscillator is
more accurate even when uncalibrated than most people have ability to
measure.
I also have both (two RbO's and 4 GPSDO's). I'll take the GPSDO any day.

Now a RbO that is GPSDO is the cat's meow.
Like my Trak 9100. Makes a nice time server on the network as well.
Also have a couple of older Efratom units.

This is not a, which one is better, question. It is a question of what is
the job you are trying to do.
