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.

Device to test mobile terminal and testing method thereof

A test signal generating apparatus for communications equipment sequentially uses first and second sequence information which are stored in a sequence memory for storing the first sequence information including a reading order and read addresses of unit data including I and Q waveform data, and desired signal levels to be set to the unit data, and the second sequence information including frequency offsets. Consequently, the test signal generating apparatus provides frequency offsets at a plurality of steps every predetermined frequency intervals by using a predetermined carrier frequency as a reference, with respect to the I and Q waveform data at a digital stage up to digital-to-analog converters, and outputs a test signal in the frequency hopping system.
