Most generic RF splitters I have worked with have DC connections between all ports. So you would need to connect one GPS directly to the splitter and then DC block the other two receivers. This is taken care of if you buy a splitter designed for GPS use. Look in the archives. GPS networking, GPS Source, HP/Agilent/Symmetricom/... all do splitters. http://gpsnetworking.com/datasheet%20replacements/LDCBS1X4.pdf Phase unbalance between the ports of <1 deg, should not contribute to you error budget significantly. kind regards, Björn _______________________________________________ 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.
