Description

Устройство дл  осуществлени  способа измерени  характеристик каналов св зи работает следующим образом.A device for implementing a method for measuring the characteristics of communication channels operates as follows.

Достижение заданного значени  уровн  сигнала «а выходе пр мого канала 1 фиксируют норотовым элементом 8 и коммутатором 7, при этом соедин ют выход нр мого канала 1 с входом обратного канала 5. По значению уровн  генератора 3, установленного с помощью регул тора 4 на входе пр мого канала 1 и измеренного измерителем 2, определ ют затухание сигналов пр мого канала 1. Затухание сигналов обратного канала 5 определ ют измерителем 6.The achievement of the set value of the signal level “on the output of the direct channel 1 is fixed by the norot element 8 and the switch 7, while connecting the output of the linear channel 1 to the input of the reverse channel 5. According to the value of the level of the generator 3, set using the regulator 4 The first channel 1 and measured by the meter 2 determine the attenuation of the signals of the forward channel 1. The attenuation of the signals of the reverse channel 5 is determined by the meter 6.
