Изобретение относитс к приборостроению и может быть использовано при настройке и контроле магнитофонов в услови х их массового производства.The invention relates to instrumentation and can be used in setting up and controlling tape recorders in terms of their mass production.
Известно устройство, предназначенное дл контрол качества каналов записи и воспроизведени информации в магнитофоне, выполненное на базе генератора последовательностей сигналов различных частот, используемого в канале записи информации, и на базе осциллографа, используемого в канале воспроизведени информации 1.A device for monitoring the quality of the recording and playback channels in a tape recorder is known, made on the basis of a generator of signal sequences of different frequencies used in the information recording channel and on the basis of an oscilloscope used in the information playback channel 1.
Однако процесс контрол при использовании такого устройства занимает достаточно большое врем , что св зано с необходимостью осуществле ни перед каждым измерением калибровки осшшпографа .However, the process of monitoring when using such a device takes a fairly long time, which is associated with the need to carry out the calibration of the collider before each measurement.
Наиболее близким к изобретению вл етс устройство дл измерени и контрол записываемой и воспроизводимой информации, содержащее р д идентичных входных цепочек, кажда из которых включает генератор синусоидальных колебаний и ждущий мультивибратор, подключенные к разным входам аналогового ключа, Closest to the invention is a device for measuring and monitoring recording and reproducing information, comprising a series of identical input chains, each of which includes a generator of sinusoidal oscillations and a waiting multivibrator connected to different inputs of an analog switch,
св занного с входом контролируемого магнита фона, индикатор и осциллограф 2.associated with the input of the monitored background magnet, the indicator and the oscilloscope 2.
Однако при использовании этого устройства также требуетс врем на частые калибровки . и перестройки контрольной аппаратуры, что удорожает производство и приводит к повыщенному расходу злектроэнергии.However, using this device also requires time for frequent calibrations. and reorganization of control equipment, which increases the cost of production and leads to increased consumption of electrical energy.
Цель изобретени - ускорение процесса контрол магнитофонов.The purpose of the invention is to accelerate the process of controlling tape recorders.
