The measurement method of non-linearity for active equipment using five carriers allows analysis of the importance and contribution of both the 3rd and 5th order intermodulation products within the active equipment bandwidth. The method of measurement requires that five carriers, equally spaced at a distance D, be applied at the input of the active equipment: (2) Measurements are made at the frequencies of 3rd and 5th order intermodulation products with significant levels, namely: (3) (4) (+++-+-e pue=-+-+e)os (beats of 5 carriers) (5) 5th order (e.g. at 2fi - Ji + fk- fz = fi- 2D or at 2fj - fk + fz - fw= i - D and at 2fz -k+j-f=w+ D'or at 2f
