Default Noise power measurement...

Hi all

I have got very simple noise source for receiver measurements, but
noise power verification makes some trouble...
Old analyzer noise floor is around -125dbm without input and noise power
using 10kHz BW is -95dbm using display 'peak' setting and long video
filter at 30MHz...

Same setup with display 'inf' setting shows -105dbm for the noise.

Sorry I don't have a manual for the analyzer to find what the 'inf'
means... but which value would be acceptable ?
I would use the first one ?
