Wireless terminal test device and timing misalignment display method for the same

Abstract

A delay addition unit that adds a propagation delay of a signal in a case of being via a satellite, which is calculated from position information of the satellite and UE, to an uplink signal from the UE and outputs the signal, a timing generation unit that generates a downlink signal and synchronizes with the UE, a power measurement unit that measures power of the uplink signal received from the UE, a reception processing unit that performs a reception process of the received uplink signal, a heat map generation unit that displays a power measurement value measured by the power measurement unit on a heat map in which the power measurement value is arranged in time series, on a display unit, and a timing misalignment detection unit that displays a position of an NPRACH of a 3GPP standard in a superimposed manner on the heat map.
