OK -- a big thank you to Paul
for his message (enclosed here) of August 26, 2007.

Using the recommended resistive divider for scope measurements I
get about 3,4V peak-peak on both output frequencies of the daughter board.

These amplitudes are quite low compared to the 3.4 Vpp that
I measured on both bands.

What is your scope probe loading on the oscillator output?

For HF and higher, I prefer resistive divider probes - 2.2 kohms
1/8w, carbon composition resistor at the tip in this case, 50 ohm
coax, to a 50 ohm DC or AC coupled load at the scope vertical input.
These probes generally have better waveform fidelity and less
overall circuit loading at HF and higher than the standard hi-Z 10x
10 pF (or 1x 100+ pF) probes (or 1x 100+ pF) as long as the
circuit source impedance isn't high.

There is more info on the web about resistive divider probes.
