This Section of IEC 60835-2 deals with methods of measurement for transmitters including modulators, and receivers including demodulators, used in digital radio-relay systems. Measurements for adaptive equalizers are given in IEC 60835-2-8. Methods of measurement for the a.g.c. characteristic, selectivity and noise figure and receiver local oscillator frequency are generally applicable only when the receiver i.f. output is accessible. This may not be the case for receivers used in systems having a microwave demodulator or a low bit rate, e.g. below 2 Mbit/s.

本标准规定与数字微波无线接力系统中所用的公务通道有关的各项测量。 在数字无线接力系统中，通常有两种基本方法用于传输公务通道信号(即话音信号、监控信号)。 第一种传输方法使用模拟传输技术，即用模拟公务通道信号对数字调制器的中频或射频载波信号直接进行频率调制，在接收端再用FM 解调器恢复(例如在相干数字解调器的载波恢复电路中)。 第二种传输方法是数字传输，即用复接器把公务通道信号以单独的比特流形式插人到主比特流中传输(可能和一个载有附加信息的比特流一起传输)。 对干数字传输，公务通道信号既可能是为了比特插人而经数字化编码的模拟信号，也可能是数字信号。在这种情况下，为了把线路码变为适于无线设备的码型，一般要进行适当的码变换。在接收端，用分接器恢复公务通道比特，经过适当的译码或码变换后，提供公务通道输出信号。 通常，要传输的公务通道不止一个有时也可以传输附加的比特流(例如供保护倒换和监视设备用的告警控制信号)。因而要使用合适的复接和分接设备，例如模拟传输使用的频分复用和数字传输使用的时分复用。使用了时分复用也就可以同时将模拟公务通道信号和数字公务通道信号用数字传输。
