Abstract

PURPOSE:To increase the operativity and then the accuracy of gain calibration, by using the output of a staircase wave generator for the control of gain of a gain variable signal amplifier. CONSTITUTION:The switch 2 is switched to the side of the calibration signal generator 1 during a calibration of gain, and at the same time the binary counter forming the staircase wave generator 9 to the generator 11. The output of the generator 11 is applied to the gain variable signal amplifier 3. Then the generation of clock pulse is stopped by the output of the comparator 8 when the output of the smoothing circuit 5 becomes equal to the reference signal of the reference signal generator 7, thus holding the output of the generator 11. After said calibration of gain, the switch 2 is switched to the input side to carry out a measurement.
