The Khoros Application Development Environment

An oscillographic ferrometer comprising a magnetizing device, magnetization and magnetizing field measurement channels and a storage means connected to a magnetization measurement channel switch and including a magnetic drum carrying a preset signal record representing the standard sample magnetization. The magnetic drum is coupled with a synchronous motor whose supply voltage frequency is of the same value as that of the magnetizing device. Two reproduce magnetic heads are accommodated in the magnetic drum housing diametrically opposite each other and connected to an adder input, one head being connected directly and the other via a signal level regulator. The adder output is connected to said switch.
