So it seems the threat of replacement and a bunch of plugging and replugging into different computers has spurred my recalcitrant GPSDO back into life and it is now producing output again... This leaves me with the original problem of low sensitivity but at least I can solve that problem by using the "replacement GPSDO" money towards connecting a better antenna.
I have a Symmetricom 58532A GPS antenna which has a N female connector but my 3 current GPS receivers all have SMA female connectors. If I want to provide capacity for at least 4 receivers fed from the same antenna, I was wondering what the best option for a splitter and where to do the N-to-SMA conversion. I currently have a Mini-Circuits ZAP3PD-2 power splitter which does SMA input to 3 SMA outputs. This seems to work but the connected devices all complain of an Antenna short, which doesn't seem good. The other popular option seems to be the Symmetricom 58536A 1x4 splitter which would then require 3-4 N-to-SMA cables - it looks like although this has gain, it seems to be more of "eliminating loss" than straight gain so would presumably not overpower the receivers' frontends. Or maybe there is another more suitable SMA splitter in the Mini Circuits confusingly extensive catalog ? Regarding hand-correcting oscillators, that's not really what I am personally in this for. I am interested in the data acquisition and analysis parts (must be the astronomy background) and so I am wanting to use the time-nuts part to learn about how to interface microcontrollers and ADCs and DACs and would like to measure things at the multi-day taus. (I'd also like to be able to eventually build a programmable delay line either to do the sawtooth correction or perform clock steering to generate and compare my own UTC(TAL), along with some means of displaying multiple timescales, which may involve another construction project as available ones either seem to have NTP servers built in or want IRIG-B or cost a fortune (unless I'm just googling for the wrong thing) Thanks, Tim _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
