This section of IEC 835-2 deals with the measurement of terminal-to-terminal protection switching equipment associated with digital radio-relay systems. The measurement methods described in this section of IEC 835-2 for an N+1 switching configuration but are also applicable to N+2 switching arrangements. The same measurement methods are applicable to 1+1, twin-path and hot standby arrangements. The channel priority status tests described in clause 5 are only applicable to the N+1 and N+2 switching arrangements. In configurations where the protection switching equipment is physically separable from the radio terminal equipment (see figure 1), the interfaces at the input and output ports of the switching equipment shall be measured in accordance with IEC 835-2-5.

This section of IEC 835-2 deals with measurements pertaining to the adaptive equalizers used in digital microwave radio-relay systems. These measurements are intended to characterize the system equalizer in the presence of selective fading and may also be performed on systems without adaptive equalizers. To take account of those properties of the system which are especially influenced by the use of frequency and/or time domain equalizers, the results of measurements performed on the system are presented by so-called signatures. Additional measurements provide further means to characterize the performance of the system.

This section deals with methods of measurement on Time Division Multiple Access (TDMA) terminal equipment. There are various type of TDMA systems which may differ, for instance, in the bit rate, the frame/burst format, and/or the acquisition and synchronization scheme. In this section, the methods of measurement are described as generally as possible so that they may be applicable to various TDMA terminal equipment used in many interna-tional and regional satellite systems.
