[SI-LIST] Radiation masking noise measurements

Hi all,
I am trying to measure noise on a small board about 2inch by 2inch with blind
and microvias. The board does not have an oscillator so we are exciting it
with a function generator. This arrangement seems to be radiating a lot and
seems to be masking the actual noise on the board. The impedance profile of
the board around the frequency fed from the function generator shows a very low
impedance and i would not expect to see such a significant amount of noise at
that frequency.
Is there any way around this problem of the noise being masked by the radiation?
Thanks in advance,
Regards,
Virendra Adsure
