Abstract: PURPOSE:To shorten a measurement time by providing an area sectioning means for waveform which the waveform to be measured into an area where the waveform exceeds a threshold value and an area wherein the waveform does not exceed the threshold value and a control means which controls the system gain of a signal processing means. CONSTITUTION:The output signal of a detector 1c is led to the 1st input terminal of a comparing means 5b. The comparing means 5b sends out pieces of information when the level of a signal applied to the 1st input terminal exceeds the threshold value (d) and does not exceed the threshold value to an area determination part 5a according to the threshold value (d) applied to the 2nd input terminal.
