scope:

The performance characteristics and methods of measurement considered are: general conditions of operation, general conditions of measaurements, general transposer characteristics, stability of the characteristic vision levels and output power, linear, non-linear and wave-form distorsions, unwanted modulation, unwanted emissions and changes in performance caused by feedback from output to input, impairments of the performance caused by coupling between output and input, special measurements for data signals in the vision signal, method of measurement of the sound channel(s).
