发明名称 COMMUNICATION DEVICE TEST SIGNAL GENERATING APPARATUS AND COMMUNICATION DEVICE TEST SIGNAL GENERATING METHOD
摘要 <p>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.</p>
