Hello. Regarding getting the cable out, on mine I have used a short length of wire-wrap wire (not a proper transmission line, but hopefully good enough to start with) that goes out through the tuning hole on the other side of the case. When closed again, the wire is clamped between the case and part of the internal metal structure, which gives it some mechanical stability as well.

The pps drive strength is a bit weak, so you need to be careful looking for it. On some units there is a software command to enable / disable it (as in pps only when warmed up and locked - like a gps). The can / cover on the unit is mu metal (Rb's are mag sensitive). If you drill a hole in it, you are likely to impact it's mag shielding properties. Bob On Sep 17, 2013, at 6:21 PM, Bob Stewart <[email protected]> wrote: > My FE-5680A Rb standard came in today. After the usual inspections etc, I fired it up and I have the purple haze. The native output is 8.38860798/9 (last digit jitter) as read on my 5335A using my GPSDO as an external standard. I've got a ways to go before it's all setup, but this is looking good. Does it warmup and change frequency at all, or can I retune it to 10MHz and use it as a reference without any further ado? > > Can someone tell me what type of socket that is where you tap off the RF? It looks sort of like a uFL connector, but a bit bigger. I'd rather avoid hacking and soldering on this if I can. > > Bob - AE6RV > _______________________________________________ > 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. _______________________________________________ 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.
