[time-nuts] Thunderbolt Harmonics

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.

R
