Abstract:
1. A method for performing the radio frequency (RF) performance test of a mobile phone, which comprises a transmitter and a receiver, the method comprising: providing a computer and an RF tester, and connecting the RF tester with the computer and the mobile phone; setting standard parameters of the transmitter in the computer; controlling the RF tester to send RF signals to the receiver of the mobile phone; processing the RF signals and transmitting the processed RF signals to the transmitter from the receiver, and reprocessing the processed RF signals and transmitting the reprocessed RF signals to the RF tester from the transmitter; obtaining resulting parameters of the RF performance of the transmitter via the RF tester; determining whether the RF performance of the transmitter is acceptable by comparing the resulting parameters of the RF performance of the transmitter with the standard parameters of the transmitter; providing a disturbance source and a combiner, connecting the computer, the disturbance source, the combiner, and the mobile phone respectively in that order, disconnecting the RF tester with the mobile phone and connecting the RF tester with the combiner, if the RF performance of the transmitter is acceptable; setting standard parameters of the receiver; controlling the RF tester to send RF signals to the combiner, and controlling the disturbance source to send channel noise to the combiner; generating combined signals by combining the RF signals sent from the RF tester and the channel noise sent from the disturbance source, and transmitting the combined signals to the receiver; obtaining resulting parameters of the RF performance of the receiver via the RF tester; and determining whether the RF performance of the receiver is acceptable by comparing the resulting parameters of the RF performance of the receiver with the standard parameters of the receiver, thereby determining whether the RF performance of the mobile phone is acceptable.
