PROBLEM TO BE SOLVED : To automatically set a mask capable of capturing an unknown extremely rare peak.
SOLUTION : A signal analyzer repeatedly stores waveform data on a signal to be measured, and detects the peaks P1 to P6 of the waveform data. A waveform width of the waveform data in a mask reference level which is decreased from the peak by a predetermined level is obtained as a mask reference width for each of the peaks, and the mask is set using the mask reference level and the mask reference width in each of the peaks. Because the mask is automatically set, a user can easily obtain time domain data or frequency domain data including a characteristic part of the signal to be measured.
