Re: [Openbts-discuss] I: Re: external Clock

[Joshua L. <jl...@th...>]

I use the FA-SY 1 and have had good results with it.  You really need to
calibrate it first though.

Check out http://www.thre.at/kalibrate .

Kalibrate uses your local GSM basestations to determine the offset of
your clock.  (GSM basestations are required to be accurate to within
0.3ppm and so are convenient to calibrate your clock against.)

So, use kalibrate to figure out your offset and then use the (Windows)
software that the FA-SY 1 came with to adjust your local clock.  (And
then use kalibrate again to make sure everything worked.)
