Как видно из этого равенства, точность измерени  чувствительност-и зависит только от точности задани  сопроти влени  в цепи источника пол  и от коэффициента нреобразовани  источника пол , которые могут быть заданы с высокой степенью точности.As can be seen from this equality, the accuracy of measurement is sensitive only to the accuracy of the matching of the field in the source circuit and the field conversion factor, which can be specified with a high degree of accuracy.

Предмет изобретени Subject invention

Устройство дл  измерени  чувствительности магнитолриемников, содержащее задающий генератор, источник цол  с магнитоприемннком , подключенный к выходу задающего генератора через блок разр дных сопротивлений , отличающеес  тем, что, с целью повышени  точности измерений оно снабжено последовательно соединенными блоком сравнени  н аналого-цифровым преобразователем, выход которого св зан с вторым входом блока разр дных сопротивлений, первый вход блока сравнени  подключен к выходу задающего генератора , а второй вход - к выходу магнитоприемника .A device for measuring the sensitivity of a magnetic receiver, containing a master oscillator, a source with a magnet receiver, connected to the output of the master oscillator through a block of discharge resistances, characterized in that, in order to improve measurement accuracy, it is equipped with a series-compared comparison unit with an analog-digital converter, the output of which It is connected with the second input of the block of discharge resistances, the first input of the comparison unit is connected to the output of the master oscillator, and the second input is connected to the output of the tape recorder Receiver.
