OK. I would still be interested to see if anyone has plots on the close
in noise profile of the Lucents. The XO part has an Efrom OCXO and I
can assume it's similar to a generic OCXO. But the RB is an unknown - I
have no idea what to expect from that.
On a separate task, one of these days I would like to build up a set of
125 & 500 Mhz sources for lab and gear use disciplined by a GPSDO 10Mhz
feed. The current source is a 125 Mhz homebrew OCXO and a pair of
doubler/amp/filter sets. I assume they are pretty clean close in but
the frequency moves around a bit more than I would like as the OCXO part
of the equation is nothing special. They drive some SDR and DDS sig
gens here in the shack so the PN is a factor as well as the frequency
accuracy.
what about disciplining the 125 MHz OCXO?
or a really narrow PLL?
