[time-nuts] My FE-5680A Came In Today

[Bob Stewart]

Hi Nigel,

All I know is what's on the ebay listing.  It's number 270851051022.  There is a tiny RF connector on the top board of the 3 that are stacked inside the package that correlates with other modded boards I've seen online.  It looks like people generally tap into that.  Mine is supposed to have a 1PPS signal on pin-6, which I do not see.  Also, there is a flashing LED inside that is not synced to 1PPS.  I dunno whether that means it's not synced up yet, or that it is.  Funny that it's just blinking, and not a 1PPS heartbeat.

Bob

>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?

  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.
