Hendrik,
the 10 MHz may not be dirty. The spectrum you show is that of a 10 MHz
rectangular wave and that's what on the output from the 10 MHz
connector, just a (may be clean) TTL-level signal, nothing fancy.

Hi List,
here is my example spectrum taken with a Rigol 815, due to inpatience
only up to 100 MHz.
(I don't know if this was posted yet, but still then it would be a 2nd,
3rd example.)
This shows what is meant by "clean 15, dirty 10 MHz." I always use
insane pre-attenuation as every beginner should do. But even a dirty 10
MHz can be good, e.g. for driving comb generators =)
