Recently, numerous research activities to upgrade the peak data rate to 1Tbit/s for 6G wireless communications are being actively conducted. The sub-terahertz band from 100 to 300 GHz is considered as a potential candidate frequency band because it is possible to secure a very wide bandwidth. Although the sub-THz band is expected to have severe path loss than the existing cellular bands, it is necessary to study channel modeling through field measurements in various indoor and outdoor environments. In this paper, we introduce a newly implemented channel sounder with a carrier frequency of 159 GHz, and conduct performance tests to verify the measurement capabilities of the system such as path loss and multipath distribution characteristics.
