GB/T 4958.1-1985 Methods of measurement for equipment used in terrestrial radio-relay systems--Part 1: Measurement common to subsystems and simulated systems--Section One--General (English Version)
The measurement method standard for the equipment used in the terrestrial radio relay system includes three parts. Part 1: Measurements common to subsystems and simulated systems. Part II: Measurement of subsystems. Part III: Measurement of the simulation system. Each part includes several sub-criteria. "General principles" is a sub-criterion in the first part, which applies to each part. The general principles are equivalent to the international standard IEC4871 "Measurement methods for equipment used in terrestrial radio-relay systems Part I: general measurements for subsystems and simulation systems Section 1 General" (now IEC487-1 [1974] Section 1 and its supplement: 487- 1A [1980]).
