*) The contracting authority accepts an analyser without automatic noise factor measurement function provided that the measurements shown in the attached diagram are guaranteed.
(Annex 1.A), by measurements using an additional external signal generator.
**) The procurer requires a set of directional power sensors to be able to measure radio power that is capable of operating with additional power amplifiers. Therefore, the upper operating range of directional power sensors shall not be less than 200 W. The contracting authority shall allow directional power sensors operating in the range (30mW)300W.
