I am just getting into the precise time and frequency stuff. I thought I should buy a GPSDO. There are quite a few similar-looking ones on eBay, such as eBay number 281802105734 There is also a Trimble at 252162780444 Would either of these be OK for a newbie like me? Richard

I am just getting into the precise time and frequency stuff. I thought I should buy a GPSDO. There are quite a few similar-looking ones on eBay, such as eBay number 281802105734 There is also a Trimble at 252162780444 Would either of these be OK for a newbie like me? Richard _______________________________________________ Richard, You might also look at a rather more versatile product - Leo Bodnar's Precision Frequency Reference (GPS Clock): http://www.leobodnar.com/shop/index.php?main_page=product_info&products_id=234 with multiple programmable frequency outputs. I have one of these and find it quite handy. For a fixed frequency board-level product, the LTE-Lite Evaluation Board: http://www.jackson-labs.com/index.php/products/lte_lite The Trimble stuff is rather dated now, and uses fewer satellites than the more recent units.

You will find most if all of these units are using a Trimble 63090/73090/65256. You will find a lot of good information on this EEVBLOG forum board http://www.eevblog.com/forum/testgear/bg7tbl-gpsdo-master-reference/ if by chance it is a Symmetricom then http://www.eevblog.com/forum/projects/a-look-at-my-symmetricom-gpsdo-(ocxo-furuno-receiver)/ As for spec and how good these are I own a the Symmetricom but don't have the equipment and more importantly the knowledge to test or give advice to others. Will defer that to the experts on Time-Nuts. p.s. if you search eBay for the Trimble with the mfg. numbers as I mentioned you will find them a lot cheaper if you want to roll out your own. -=Bryan=- > From: rchrdm@earthlink.net > Date: Sat, 2 Jul 2016 21:28:12 -0700 > To: time-nuts@febo.com > Subject: [time-nuts] Good GPSDO? > > I am just getting into the precise time and frequency stuff.
