PURPOSE: A multiband signal analyzer for a wireless station of a mobile WIMAX is provided to analyze a mobile WIMAX wireless station signal by one hardware structure. CONSTITUTION: A digital low pass filter(50) passes a baseband frequency signal. The digital low pass filter changes a cut off frequency by changing a coefficient. A symbol rate converting unit(60) enables a baseband frequency signal passed through the digital low pass filter to have a symbol rate which is integer times larger than a reference clock of a signal analyzer. A signal analyzing unit(70) calculates a signal analysis parameter for analyzing a signal of a wireless station from a signal inputted from the symbol rate converting unit. The signal analyzing unit analyzes a signal by the calculated signal analysis parameter. |
