I'd second that, sounds interesting and plenty of accuracy for the project
I'm thinking of.

I am still learning and want to understand, if the PPS is good then why is
the programmable output bad, as I understand it thus far, the PPS is
derived from the same clock source or have I got that badly wrong?

The 9851 will work with pretty much any clock and give an output but of
course you need a decent speed clock to get a useful range of frequencies.
The handy feature of the 9851 is that it has a clock multiplier built in so
that 30MHz can clock it at its maximum speed and give a useful DC-60MHz
out
hough.

Bryan, I think we do, bought from an eBay seller named Fluke.I?
I also found that schematic but it's a partial, very useful nonetheless.
There's also a dump of the firmware and CPLD so I'm hoping I can make some
sense of that to work out the CPLD, I'd be happy with a solid 10MHz output
but to my
I've made some investigations and re-confirmed my earlier findings on the
FE-5680B I have.
It locks from cold in under five minutes and runs at approximately 700mA
steady with the expected PPS signal on the output connector when locked.
The particular 5680 I have has a Hi Density 15p male connect
The 10MHz output comes from the XC9572 CPLD but the fact that it's there
for a few seconds makes me thing it's possible to recover it, by fair means
or foul.
It's possible it's just a gate, certainly looks like it's bing switched off
and there's a file which claims to be a dump of the CPLD (as wel
itor point) by at least 0.15

I've recently purchased one of the PPS Only FE Rubidium standards from eBay
and, like many others I suspect, haven't been able to get a stable output
frequency that lasts longer than a few seconds from the module.
It appears that the 10MHz source vanishes after a few seconds but this is
controlled
