So I have to check that also: it shows 46 pF on 1x mode and 10.6 pF in 
10x mode.

Ok so the main question is that what kind of amplifier I should use with 
10544A to get a clean signal, if it can't stand even an oscilloscope 
without distortion on it's output? And what do that kind of amplifier 
cost - more than HP10811, for example?

Many other OCXO's (like thunderbolt's) can be connected directly to the 
50 ohms. load without any trouble with harmonics.
