[time-nuts] Chooses for a desktop/server NTP external 1PPS reference

[Robert Atkinson]

Hi Alexander,
Welcome to the list.
Another professional option is the Trimble Accutime Gold. http://www.trimble.com/timing/  The older Accutime 2000 and Palisade turn up on ebay. A desk top box is the CNS Clock II http://www.cnssys.com/cnsclock/CNSClockII.php cost about $3000 complete. 
Some idea on if you want new / professional or used / amateur and if you are a keen constructor would allow more targeted advice.

Hi Everybody:

First post, be gentle.  I did some mail-list archive searching and it seems
that a lot of folks have used the Garmin 18x LVC as their 1PPS sync for the
desktop with varied success (5V via USB port and RS-232 for 1PPS?).  At
work, I have experience with an Endrun Cf/Ct receiver connected to a small
CDMA antennae (as well as GPS receiver) which works pretty well (I suppose
its more relative to my crappy motherboard oscillator than anything).  I
have no idea how much they run (I think the CDMA one was like $200 and
something).

What are my options in this realm?  Surprisingly enough, Googling for over
an hour didn't yield much results.  There are tons of companies that offer
various solutions but with little pricing information.  I'd be happy to hear
some suggestions OTHER THAN the Garmin 18x LVC?

(btw is there such a thing as a desktop rubidium atomic clock with 1 PPS?)

Thanks!
