Hi, For a low cost startup have a look at a picPET < http://www.leapsecond.com/pic/picpet.htm > and TimeLab < http://www.ke5fx.com/timelab/readme.htm > Less than $10 including shipping!

For the last couple of years I have been increasingly involved in various work involving IEEE 1588 and finally I started fitting out a small home lab setup. I never really needed lab kit at home before and my work lab is primary to do with Ethernet and IP (and timing, but outside my price ranges), so I was wondering if you could point me in the right direction: I'm looking for some reasonably inexpensive solution to allow me a) to do TIE measurements of 1PPS signals against a reference and b) do phase comparisons of different 1PPS signals - so something with REF and at least two inputs. I have an OCXO GPS reference (upgradable to Rb) with 1PPS, 5MHz and 10MHz outputs which is stable enough for my needs so that part (perhaps most important) is sorted. In terms of requirements, granularity wise, well, as good as achievable - I'm used to 10 ns and 5 ns granularity with TIE that I get from work kit. 50 ns or better would be perfect. I must add that ideally I would like to avoid having to design or build the kit myself - I would love a project, but I have time to spare to complete one. Any pointers much appreciated.
