PURPOSE:To obtain easily the information necessary for an adjustment of a characteristic stabilizing circuit, by securing automatic storage of the machinery characteristic caused by a change of conditions of ambient temperature. CONSTITUTION:The system includes a signal generator 1, a variable attenuator 2 for compensation of gain, an amplifier 3 functioning as a substance to be compensated, and a circuit 5 which feeds the output of an output level detector back to the attenuator 2. A controller 6 switches the temperature of a thermostatic chamber A in a prescribed sequence and at the same time gives a signal commanding that a storage circuit 7 must store information simultaneously with the temperature information of chamber A set to the circuit 7 and with a proper time interval. The circuit 7 stores both the temperature information and the output information of the circuit 5 based on a command given from the controller 6. In such way, a condition under which the gain combining the attenuator 2 and the amplifier 3 becomes steady to the temperature can be stored automatically. |
