During my efforts to find a standard that could serve as reference to help characterize my FTS1050, I went thru a succession of 10811's, several stand alone datum 1000's from the usual auction site, an HP105B, a wenzel from the usual auction site etc and none of them came even close to the adev performance at tau's of 40 to over 10,000 seconds of the BVA 8600 I purchased. (I can't measure phase noise or adev tau's less than approx 40 seconds.) The only other reference I've been able to acquire that is close to being in the same league as the BVA8600 and the FTS 1050 is a single Z3805 at certain tau's (out of approx half a dozen assorted GPSDO's.)
My BVA wasn't inexpensive either but it performed as I expected. I also suspect it out performs the FTS1050 at shorter taus's. I also considered buying an HP5065 as an alternative but figured there was less to go wrong with a stand alone OCXO. I figure I got lucky when I acquired my FTS1050 and one of my Z3805's. I don't believe luck played much of a role in my BVA purchase. Your experience may vary.
