Downlink signals output from a transmission and reception unit are combined with an interference signal of a CW, a resultant signal is applied to a mobile terminal, throughputs for respective interference signal frequencies for the downlink signals are collectively measured, a signal suppression band of the filter is fitted to a frequency band of the downlink signal determined not to reach a defined value, and re-measurement and re-determination of the throughput for the downlink signal among the collectively measured throughputs are performed. In a case where throughputs collectively measured at a certain interference signal frequency are equal to or greater than the defined value and a case where re-measured throughputs of all the downlink signals are equal to or greater than the defined value, the interference signal frequency is switched to the next interference signal frequency, and collective throughput measurement is performed.

Mobile terminal test device and method

Setting means does not respond to a transmission signal from a mobile terminal for a predetermined period of time and sets the mobile terminal to a designation value saturation level excess state during a random access process. Data transmission instruction means allocate M resource blocks and N resource blocks (where N is less than M) to the mobile terminal in the designation value saturation level excess state, respectively, and instruct the mobile terminal to transmit signals in which data are inserted into the allocated resource blocks. Power measurement means measures the power of the signals. Determination means determines whether a difference between the measured values when the numbers of resource blocks are M and N is within an allowable range and determines whether the mobile terminal quickly responds to an output power reduction instruction on the basis of the determination results.

Mobile terminal test device and mobile terminal test method

A mobile communication terminal test device includes: test signal transmitting means () for transmitting, to a mobile communication terminal (), a test signal including a plurality of radio resource regions (to) each of which is surrounded by one or more sub-frames and one or more resource blocks; and response signal receiving means () for receiving a response signal to the test signal from the mobile communication terminal. The test signal transmitting means transmits, to the mobile communication terminal, the test signal which includes one radio resource region for each predetermined time interval (T) and in which the position of the radio resource region in the frequency axis direction varies for each predetermined time interval.

Mobile communication terminal test device and mobile communication terminal test method

A portable radio terminal testing apparatus has an antenna coupler, a connecting member, and a measuring device. The antenna couplerhas a placement member, a coupling antenna, a pair of through-connection portions, and an impedance transformer. The placement memberaccepts a portable radio terminal, which is a testing object, in an unrestricted state. The coupling antennais disposed so as to be electromagnetically coupled with an antennaof the portable radio terminal, and has a pair of antenna elements which are formed at one face side of a dielectric substrateand which have a planar antenna structure of a predetermined shape, and a pair of feeding points, and is formed from a self-complementary antenna having a predetermined impedance within an operating frequency range including at least 800 MHz to 2.5 GHz order.
