Hello all:

I considering a do-it-yourself GPSDO, and I started by looking for a
good OCXO. I have been given a quote for a unit with the following
phase-noise numbers:

-120 dBc/Hz at 10 Hz
-145 dBc/Hz at 100 Hz
-155 dBc/Hz at 1 kHz
-160 dBc/Hz at 10 KHz
-160 dBc/Hz at 100 KHz

My question is this: Are these good specs? They look pretty good to
me, quite comparable to the HP 10811 numbers.
