GB/T 4958.8-1988 Methods of measurement for equipment used in terrestrial radio-relay systems--Part 2:Measurements for sub-systems--Section Eight Radio receivers (English Version)
This standard specifies the measurement methods for the electrical characteristics of receivers (excluding sub-channel networks and switching networks) applicable to terrestrial radio-relay systems. The block diagram in Fig. 1 is a functional block diagram of this type of receiver, and the actual block diagram of the receiver may have differences in details, for example, some functional blocks such as radio frequency amplifiers may be omitted.
