As much as can be told from a 17 minute plot - looks ok. The antenna could
indeed be a bit higher and that would hopefully take care of the crummy sat c/n

Hi
Has anybody traced out the connections on the DB-37 connector on the back of
this beast yet? It's not quite the same as the 110 pin connector on the back of
the NTBW50AA. I suspect it's got the same sort of stuff on it.

If there was a file / image attached , it didn't make it through. North doesn't

Hi Alan,
finally I solved the issue removing the 1121 board from the pts3200
and putting a 1121 board from a pts160 and now works perfect.
Looks that the unit have some customizations from the manufacturer.
Thanks for all guys.

Mark,

I think, you won't change anything on the latter parameter by re

The alignment procedure mainly calibrates the absolute T.I. accuracy to

I am interested in the timing behavior of my RSA fob, which changes
every 60 seconds. Since I'm not about to open it up and probe inside, I
was wondering if someone had a clever way, say using a USB web cam, to
log the changes over a 48 hour period. You'd point the web cam at the
fob, and it

Hi
In any closed loop system, it's a bit hard to be 100% sure what moved and what
responded to the move. For instance, the reference voltage to the DAC could be
jumping. The only way to be sure is to tear everything apart and monitor each
piece long term.
That said, yes its about 99.(insert s
Claude,
I see a jump even smaller than the first one and as I calculated before
(in an answere to Said's mail) this latest jump is much less than the
first one of 550 microHz. I agree with Said that this could be a crystal
jump.
If you want to check the GPSDO's absolute frequency you'd need

After these ten, it will be a matter of reordering boards if there is enough
interest.
