  • IEC 60487-3-2-1981 - 中外标准 - - 1981/1 - 现行
    Deals with baseband measurements on simulated radio-relay systems which are not directly related to a particular type of signal actually being transmitted. These measurements are carried out typically at the modulator input and the demodulator output points and exclude auxiliary terminal equipment.
