Abstract
A device under test (DUT) may be connected to test equipment. The test equipment may include a multi-carrier signal generator and a host computer. The signal generator may provide a multi-carrier test signal that is fed to input-output devices of the DUT. The DUT may tune to a given radio channel on the test signal. The DUT may output an audio signal to the host computer to test for audio quality. Once desired measurements have been taken, the DUT may scan up or down to the next available radio channel on the test signal. The signal generator may not need to be reconfigured between scans, because the test signal contains multiple radio channels. The host computer may run a test program that directs a test program running on the DUT to perform the required tasks during testing.
