Description
пульсов, пороговый блок 12, блок 13 управлени .pulses, threshold unit 12, control unit 13.
Устройство работает следующим образом.The device works as follows.
На передающей стороне испытательный сигнал с выхода генератора 1 поступает на вход аттенюатора 2, который управл етс от генератора 11 таким образом, что на вход измер емого канала через усилительOn the transmitting side, the test signal from the output of the generator 1 is fed to the input of the attenuator 2, which is controlled from the generator 11 in such a way that the input of the measured channel through the amplifier
3испытательный сигнал поступает с периодически чередующейс величиной уровн ,- номинальной и повыщенной (больше VIOминaльнoй на 6ч-8 дБ). На приемной стороне сигнал с выхода канала поступает на фильтр 4 и Б блок 5. На выходе фильтра 4 сигнал по вл етс в том случае, если на вход канала подан сигнал повыщенного уровн , и происходит ограничение сигнала. При подаче на вход канала номинального уровн напр жени в канале ограничени не происходит, поэтому на выходе фильтраThe test signal comes with a periodically alternating level, nominal and higher (more than 6 min-8 dB VI). At the receiving side, the signal from the channel output is fed to filter 4 and B block 5. At the output of filter 4, the signal appears when a signal of a higher level is given to the channel input, and the signal is restricted. When a nominal voltage level is supplied to the channel input, the limiting channel does not occur, therefore, at the filter output
4сигнал практически отсутствует. Моменты по влени и исчезновени сигнала на выходе фильтра 4 фиксирует блок 12. Блок 13 управл ет блоками 7, 5, 10, задава следующий алгоритм измерени . По изменению на входе канала уровн испытательного сигнала от повышенного к номинальному блок 13 вырабатывает команду в блоки 5 и произвести измерение уровн сигнала, поступающего на вход блока 7 через детектор 6. По изменению па входе канала уровн испытательного сигнала от номинального к повышенному блок 13 вырабатывает команду на повторное уравновешивание, а затем на выработку поправки блоком 10.4 signal almost absent. The moments of occurrence and disappearance of the signal at the output of the filter 4 are captured by block 12. Block 13 controls blocks 7, 5, 10 by specifying the following measurement algorithm. By changing the level of the test signal from the channel to the nominal, the unit 13 generates a command in blocks 5 and measure the level of the signal to the input of block 7 through the detector 6. By changing the input channel level of the test signal from the nominal to the high, unit 13 generates a command on rebalancing, and then on the development of the amendment unit 10.
Устройство дл измерени порога перегрузки в каналах св зи позвол ет уменьшить врем измерени и исключить дополнительный канал св зи.The device for measuring the overload threshold in the communication channels reduces the measurement time and eliminates the additional communication channel.
