Did you happen to spot any service/calibration manuals
for the 35601A? I haven't found anything online yet, but one
of the manual dealers I checked lists a hard copy.

 I've never used the older 3047a, but the impression I have from the
catalog info I've found so far is that the 3048a updated to the newer
3561a for narrowband analysis and added more internal sources
to the 11848a for convenience; I'm hoping that much of the basic
signal path for calibration and quadrature lock was left alone.

 I need to measure things that are lower close in than the 11729/8662a
combo noise floor; i.e. OCXO, direct synthesis from OCXO, amp/divider
residual noise floors, down to 1-10 Hz offsets.

How many significant digits are there in a 5120A price quote? 
That doesn't go high enough for everything I need to do, but
looks much handier for <30 Mhz
