Abstract: PURPOSE:To improve the accuracy of waveforms by obtaining characteristics of a digital filter for flatly correcting the frequency characteristic without phase distortion when the frequency of a sine-wave generator is sequentially changed, correcting the values at the time of waveform measurement after calibration, and processing the waveforms to be displayed. CONSTITUTION:A CPU 9 drives a switch 7. The output of a sine-wave generator 1 is inputted into an AD converter 8. The frequency is sequentially changed, and the values of the levels are measured. Then, the output of an input circuit 6 is connected to the converter 8. A probe 4 is connected to a CAL terminal 3. The frequency of the oscillator 1 is changed by the same way described above, and the values of the levels are measured. The transfer characteristic of the circuit 6 and the change when the frequency has the lowest value are obtained with the probe 4 based on the measured result. Then, the characteristics of the digital filter for compensating the change are computed in the CPU 9. The output of the converter 8 is corrected and computed in the CPU 9 based on the digital filter characteristics. The result is stored in a memory 10.
