Abstract
Disclosed herein are a WiMAX system analyzer having an RAS emulation function and a method of acquiring UL synchronization and testing a PSS. The WiMAX system analyzer includes a clock counter, a D/A conversion unit, an A/D conversion unit, an RF processing unit, switching means, a signal generation unit, a signal analysis unit, and control means. The clock counter creates a frame number. The D/A conversion unit converts a DL sub-frame into an analog signal. The A/D conversion unit converts a UL sub-frame signal into digital data. The RF processing unit RF-modulates the DL sub-frame, outputs the modulated DL sub-frame, and demodulating a modulated UL sub-frame. The switching means connects the RF processing unit to the D/A conversion unit or the A/D conversion unit. The signal generation unit assigns a CID, and creating a DL sub-frame. The signal analysis unit decodes the UL sub-frame, and conducts various analyses. The control means performs control so that the switching means connects to the A/D conversion unit.
