scope:
This section deals with basic measurements which are equally applicable to a sub-system such as an amplifier, or to a combination of sub-systems assembled to simulate a satellite earth station. Methods of measurements are described for the following parameters: - input and output impedance (return loss); input and output levels; - baseband gain or loss; - amplitude/frequency characteristics; - group-delay frequency characteristic; - non-linear amplitude distortion; - differential gain and phase distortion. Methods of measurement for parameters which are related to a specific baseband signal such as frequency division multiplex telephony or television transmission, are given in Part 3 of the standard.
