This section of IEC 835-1 deals with the measurement of transmission performance and is applicable to simulated digital microwave transmission systems or sub-systems.
The transmission parameters should normally be measured at interface points recommended by the CCITT (see [l]). In special cases when equipment specifications require measurements at other ports (e.g. between modulator input and demodulator output terminals), interface circuits between the measuring equipment and the equipment under test may be necessary.
