Summary: This standard specifies for terrestrial radio-relay systems receiver (not including sub-channel network and switching network) measurements of electrical characteristics. 1 is a block diagram of a functional block diagram of such a receiver, a block diagram of the actual receiver, the details will vary, for example, may be omitted if some function blocks: a radio frequency amplifier. Noise of the local oscillator, while the receiver is an important indicator of the receiver is generally not measured, but the measurement of radio-relay systems in the baseband terminal device. Since the formation of the path loss index only independent baseband noise, therefore, not considered in this standard.
