I have Z3816A's and TBolt's. Both do a great job. For the TBolt, I use TBoltMon.exe to monitor and for the Z3816A, I use SatStat. The Z3816A requires a 'null modem' adapter or an appropriately wired serial cable to connect to the serial port of the computer where as the TBolt uses a straight serial cable.
The only potential advantage of the Z3815A that I know of is the fact that it uses the E1938A oscillator. I have a couple of these oscillators and they are superior in performance. However, I have no firsthand knowledge of performance of the Z3816A versus the Z3815A. The Z3816A and the TBolt tracks up to 8 satellites. The Z3816A also tells you what other satellites are under consideration but are not being tracked, perhaps up to 8 other non-used satellites. I have at most seen the Z3816A refer to a total of 11 satellites (8 tracked and 3 not tracked) but my antenna is not in an ideal location. I do not know about the Z3815A. The Z3805A tracks up to 12 satellites, if I recall correctly, and probably should also be included in the comparison list if you are looking for a GPSDO. The Z3816A comes in at least two variants, one powered by a DC supply (I use 30 VDC for mine) and the other powered by 120 VAC. I don't know about the Z3815A.

I also see a Z3815A on Ebay, but the connector arrangement is not attractive. Does anyone have a link to a comparison chart between all these models? _______________________________________________ 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. _______________________________________________ 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.
