Abstract: A communication test device can assist in identifying a cause of the change in throughput of a mobile communication terminal. The device includes accumulating means for accumulating trace data on a specific unit of data complying with a designated communication standard, and throughput data on throughput of the specific unit of data transmitted to and received from a mobile communication terminal, extracting means for extracting trace data and throughput data from the accumulating means, trace display means for displaying trace data on a display unit, throughput display means for displaying a graph of the variation with time of throughput on the display unit, and time obtaining means for obtaining a time. The extracting means is adapted to extract, from the accumulating means, trace data corresponding to time designated by an operating unit. The trace display means displays the trace data corresponding to the time on the display unit.
