Hi Bjoern, I respectfully disagree. I measured the loss through the GPS amp and Mini Circuits splitter at only 10.1dB. That's really not a lot. I couldn't find a loss-spec in the Thunderbolts' specification. The Agilent amp has GPS filters in it that improve signal quality by filtering out all non-GPS signals. Someone else had the same problem here (that's how the discussion initially started) thinking his Symmetricom splitter was dead. I think it's safe to say a GPSDO can be expected to work with a name-brand GPS splitter (which it did not either for the other gentleman). So if the M12+, M12M, and all other GPS receivers I have can all handle this signal without a hitch, except the Thunderbolt, then this means the Thunderbolt requires special attention (or in my case possibly it's own GPS antenna). I will try to change the AMU settings as Warren suggested, that makes sense. Maybe this is what we should have tried from the beginning to make our Thunderbolts work? bye, Said In a message dated 11/21/2009 14:18:51 Pacific Standard Time, [email protected] writes:
Hi Said, As we talked about some weeks ago... your test is unfair to the Tbolt, but that is perhaps intentional. The Tbolt will need more gain to work. You are giving it a signal that is out of spec. -- Björn _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
