Patent ID: 8768340

Claim:
A mobile communication terminal testing apparatus that tests a mobile communication terminal that transmits or receives a signal of a radio frequency which includes a plurality of slots delimited at a predetermined time interval, each of the slot including a plurality of symbols modulated according to a predetermined modulation scheme, the mobile communication terminal testing apparatus comprising: reception signal outputting means that receives a transmission signal of the radio frequency from the mobile communication terminal, converts the transmission signal into a baseband signal, and outputs the baseband signal; modulation accuracy measuring means that measures modulation accuracy of each of the plurality of symbols included in the baseband signal; slot selecting means that selects at least one of the plurality of slots; and display means that displays the modulation accuracy of each of the plurality of symbols included in the slot that is selected by the slot selecting means wherein the modulation accuracy measuring means measures the modulation accuracy of a measurement target symbol set in advance out of the plurality of symbols included in the slot, and wherein the mobile communication terminal transmits the transmission signal in which a plurality of the symbols modulated according to the predetermined modulation scheme are allocated to areas set in advance in both time domain and frequency domain.
