Main spectral component from 600 radiated-emissions records of the quasi- QKD receiver measured by (FFT1) vertically and (FFT3) horizontally polarized antenna. Two antennas were used to capture horizontal and vertical polarized emissions at 3-m distance. The received signals were amplified and measured with a 1.5-GHz bandwidth oscilloscope. The quasi-QKD receiver was located on a non-conductive table at 80-cm height. Frequencies for each record are in arrays FFT1max and FFT3max. Magnitude for each record are in arrays FFT1maxVAL and FFT3maxVAL. Frequencies are in Hz and magnitude is in V.
