Well... in fact, that's sort of the question I'm asking. if one does
search Ebay, what's an effective search term?
Leaving aside the $60 Nike Cesiums...
Were you aware that you can add terms in the search box preceded by a
negative sign to exclude items that match that? ie cesium -nike
Hello Bjorn,
My OCXO is marked: Model 2000A Serial Number 311. No freq is given. It is
almost certainly 10 MHz.
The oscillator does have that weird D-SUB+coax on it. The PCB on the module
wires it to a DB9 connector with the Dataum 1000 OCXO. Measured voltages were
around 15V and 26V.
Does anyone on this list have a PDF copy of a manual for the Truetime MODEL
505-107 GPS -TMS? I have a customer who is requesting one.

a simple question
for you you Thunderbolt Experts. After reading the Trimble Manual,

lock. I desire to
That is an RS-232 port; there's no locked line on it (although I agree
there should have been.) You'll need to run TBoltMon.exe to monitor its
status, or talk to Mark Sims about the dedicated Thunderbolt controller he
mentioned he was developing.

Thanks John, I was afraid of that, what a shame they did not include a lock
line on the
RS-232 Port. As I said I was trying to oversimplify. There certainly is a
lot of Technology in that very small box. Good luck.

Here are the pinouts of the FTS 2000A OCXO jumper board in my 4060M/S24 cesium
beam unit.
This board makes the 2000A look like a Datum 1000 OCXO.
Datum 1000 pinouts and definitions are from Brooke Clark's PRC68.COM web site.
The FTS-2000A coax connects to an SMB connector.
