Abstract: At the beginning of the operation of a mobile terminal 1 to be tested, link establishment means 211 performs a process of establishing a link to the mobile terminal 1. When the link is established, test mode change means 213 transmits a message “downlink Direct Transfer (Activate RB Test Mode)” for setting test mode connection from a base station, returns a response message to a message transmitted from the mobile terminal 1 to be tested, thereby changing the mobile terminal 1 to be tested to a test mode, and performs a transmission and reception test.

Abstract: At the beginning of the operation of a mobile terminal 1 to be tested, link establishment means 211 performs a process of establishing a link to the mobile terminal 1 and location registration means 213 performs a location registration process. Then, test mode change means 214 transmits a message “downlink Direct Transfer (Activate RB Test Mode)” for setting test mode connection from a base station, returns a response message to a message transmitted from the mobile terminal 1 to be tested, thereby changing the mobile terminal 1 to be tested to a test mode, and performs a transmission and reception test.

Abstract: A mobile terminal testing device includes a reproduction unit that reproduces a BB signal to output at least one reproduced BB signal, an adder that adds a BB signal that are frequency-shifted and a reproduced BB signal to output an added BB signal, an up-converter that generates a multicarrier test signal by making a frequency conversion of the added BB signal of an I phase and Q phase and outputs the multicarrier test signal to UE, and an analyzer that analyzes a response signal output by the UE in response to the multicarrier test signal and the analyzer includes a throughput calculation unit that calculates throughput for the multicarrier test signal and an RSRP acquisition unit that acquires RSRP.

Abstract: To enable addition or changes of functions with changes of communication standards in a mobile communication terminal test system. A mobile communication terminal test system includes a transceiver which has a control unit configured to append input information to acquired waveform data, a signal analysis unit which executes an analysis program, and a signal analyzer which is provided separately from the transceiver. The analysis program has a processing program which is provided for each type of arithmetic processing on the waveform data, a control program which is provided for each communication system, selects one or more processing programs for each test item, and executes the processing programs, and a switching program which specifies a communication system and a test item on the basis of the input information, and selects and executes a control program.

Abstract: A signal analyzer for facilitating observation of a relative value, i.e., the quantity of variation in power between slots, at the time of analyzing the power of a signal which is to be measured and subjected to power control in units of slot. An analyzing section detects the power value of every slot of a signal which is to be measured and received at a receiving section, and calculates the relative value of the power value between each slot and a slot separated therefrom by a predetermined number. A display control section displays the relative values thus calculated as a graph at a display section by arranging them continuously in time series.
