Изобретение относитс к измерительной технике.This invention relates to a measurement technique.
Известны устройства дл спектрального анализа сигналов в канале магнитной записивоспроизведени , содержащие усилитель записи с регул тором уровн записи, полосовые фильтры и блок измерени . Недостатком известных устройств вл етс узкий динамический диапазон анализа.Apparatuses for spectral analysis of signals in a magnetic recording-reproducing channel are known, comprising a recording amplifier with a recording level control, band-pass filters and a measuring unit. A disadvantage of the known devices is the narrow dynamic range of the analysis.
Дл получени максимального динамического диапазона анализа в предлагаемое устройство введен переключатель полосовых фильтров, св занный с блоком измерени и регул тором уровн записи.In order to obtain the maximum dynamic range of analysis, a bandpass filter switch is introduced into the device associated with the measurement unit and the recording level controller.
На чертеже изображен вариант описываемого устройства, содержащего усилитель 1 записи с регул тором 2 уровн записи и индикатором 3 уровн , канал 4 записи-воспроизведени , усилитель 5 воспроизведени и полосовые фильтры 6 с различными полосами пропускани , выходы которых через переключатель 7 св заны с блоком 8 измерени .The drawing shows a variant of the described device comprising a recording amplifier 1 with a recording level controller 2 and a level indicator 3, a recording / playback channel 4, a playback amplifier 5 and band-pass filters 6 with different passbands, whose outputs through switch 7 are connected to block 8 measurements.
В зависимости от полосы пропускани анализатора , определ емой полосой пропускани подключенного фильтра 6, устанавливаетс оптимальный уровень записи. Установка уровн записи производитс регул тором 2 за счет св зи, например, механической, с переключателем 7.Depending on the bandwidth of the analyzer, determined by the bandwidth of the connected filter 6, the optimum recording level is set. The setting of the recording level is made by the controller 2 by communication, for example, mechanical, with the switch 7.
