5.3.3.2 Vector Diagram
The Q component is displayed over the I component in the vector diagram. Each point
is determined by a vector. The amplitudes of the signal components scaled to the peak
envelope power (PEP) are plotted on the X and Y axis (minimum scaled amplitude =
-1; maximum scaled amplitude = +1).
This display shows the curves between the various states of modulation mapping. The
recording depth is 1 kSamples.
This signal is picked off at the output of the baseband main module ("Impairment" func-
tion block), i.e. contained in the displayed signal is:
●
impairment of the signal as defined by the user and the addition of noise.
