Abstract
A signal analyzer repetitively memorizes waveform data of a signal under test to detect peaks P-Pof the waveform data. Waveform widths of the waveform data at a mask reference level, or a predetermined level down from the respective peaks, are evaluated as mask reference widths and then masks of the respective peaks are set using the mask reference level and mask reference widths. Hence the masks are automatically set, so a user can easily obtain time domain data and/or frequency domain data including characterizing portions in the signal under test.
