Hi,
The -60109 usually does have the very good short term stability at short
Tau but to actually use it you need to go open loop on the 5065A or
5061A/B.
In closed loop the instrument actually drives the stability and pretty
much any 10811 variant will work.
HP knew this and recommended going
Hi John,
Since TOPCON is a manufacturer of topographic instruments, I think that
this antenna is used for this kind of work. GPS antennas made for
geodesy or surveying usually have a very good quality and their prices
are according to it.
But given the label at the bottom it could be used
Hi
Again, there is no basic difference between the 10811-60109 and any
other 10811 with the same basic pinout. ( They made two packages,
one with an edge connector. Eventually they wrapped one up to put it
in a GPSDO). The only difference between the 60109 was a test and
select process back

It seems like you are mixing up here quite a few different concepts:
Phase noise vs amplitude noise, additive
Hi
You just might find that kit will drop into a 5065 with minor
mods…..

Hi everyone,
Last month, I bought a 10811-60109 on ebay, it was sold with the
complete oscillator assembly for a 5061A/B cesium clock.
I bought it for the 10811-60109 because it has somewhat better
specifications than a regular 10811.
It was sold as a spare from military surplus. I've taken a

Yes - I have performed this upgrade, having obtaineda 10811 / high performance
option.
While the complete original HP kit was not available, I salvagedthe 10->5 MHz
divider/connection board from a 105Band re-designed the back PCB with the 2 x
15pole 3.96 pitch connectors and
