METHOD OF MEASURING BAND NOISES OF TRANSMITTER AT CARRIER NEIGHBORHOOD Russian patent published in 1994 - IPC

FIELD: measurement technology. SUBSTANCE: measurements are conducted in noise band of the transmitter: 1) values of dispersions of noises at measured band of the first transmitter and at frequencies which belong to the band of the second transmitter according to preset misalign of carriers; 2) identical characteristics of the second and other transmitters; 3) sum of dispersions of noises in the band of transmitter measured and noises which belong to the band of transmitter measured from adjacent ones with account of re-count of noise frequency relatively carrier of transmitter to be measured; 4) values of dispersions of noises in measured band ΔF₁ at combined operation of the transmitters and difference between noise dispersion measured and sum of dispersions of noises. This difference characterizes effect of parametric effect onto operation of transmitters. It is distributed between the transmitters proportional to levels of signal components and is added with dispersions of noises calculated from the relation given in the description of the invention. EFFECT: improved precision of measurement. 1 dwg
