Scope

This standard gives methods for measuring the electrical performance of frequency modulators and, as far as possible, only involves the measurement of basic modulators, but does not include the combined network of pre-emphasis networks and sound subcarrier signals, pilot signals and auxiliary signals. The baseband part consists of. Chapter 5 gives the measurement method of frequency demodulator. Measurements between baseband terminals of modulator/demodulator combinations are described in the chapters of Part 3 of this series of standards.
