Summary
This standard specifies the basic measurement methods such as amplifiers and other related subsystems or subsystem composed by the simulated radio relay systems. This standard applies to the following parameters of the baseband range of measurements. Input and output impedance (return loss); input and output level; baseband gain or loss; amplitude frequency characteristics; group delay frequency characteristics; nonlinear amplitude distortion; differential gain and phase distortion.
