Spectrum analyzer having means for displaying spectrum data together with power value thereof

摘要

A directing section (105) substantially directs an input signal to first and second paths. A signal pro­cessing section (101) outputs spectrum data correspond­ing to the input signal directed to the first path. A power detecting section (106) detects a power value corresponding to the input signal directed to the second path. A display section (104) displays the power value together with spectrum data.
