Is what your seeing a harmonic (2nd? 3rd?) or a spur i.e what frequency
is the "harmonic" ?
How are you measuring this ? (Spectrum analyzer ? make/model?)
More importantly and at the risk of displaying my naivety, what is the
application that you are using the 10MHz source to feed and why if this
harmonic is 60db down (or even only 40db down, the quoted spec) why
would one care? What is the predicted error you will get in your
application as a result?

Hi all,
Before I start, let me say I'm rather a newbie at this sort of stuff so
please be gentle.
I was looking at the output of my Trimble Thunderbolt GPSDO and was rather
surprised to see really "loud" harmonics in there. ~ 60dB down from the
10Mhz signal.
Can anyone here shed some light on what I am seeing here?
Surely this isn't what it is supposed to look like? Should I be trying to
filter these before going to my distribution amplifier?
Thanks for any light you can shed.
