Abstract

To provide a mobile communication terminal test apparatus capable of displaying an EVM or a transmission power measurement result in a frequency division multiple access communication scheme by distinguishing between the allocation band and the non-allocation band. A test signal including control information representing the communication channel and the allocation band is transmitted to the mobile communication terminal, the test signal output from the mobile communication terminal is received, the output waveform data are analyzed, a measurement value of a predetermined measurement item is obtained on a symbol-by-symbol basis, the obtained symbol-based measurement value is displayed on a graph, and the allocation band on the corresponding graph and the non-allocation band within the communicate channel are displayed to be distinguished therebetween.

Description

technical field [0001] The present invention relates to a test device and a test result display method, which measure a signal from a mobile communication terminal, and display the measurement result in the allocated frequency band assigned to the mobile communication terminal in the channel of the signal and the measurement result in the channel respectively. Measurement results in frequency bands other than the allocated frequency band. Background technique [0002] Conventionally, there is known a mobile communication terminal testing device that tests transmission and reception characteristics of a mobile communication terminal. The mobile communication terminal testing device has a transmitting unit for transmitting signals to the mobile communication terminal and a receiving unit for receiving signals from the mobile communication terminal, and operates as a simulated base station to transmit and receive signals with the mobile communication terminal, thereby testing t...
