Wireless test equipment may be used to perform over-the-air testing of user equipment. The user equipment may contain an antenna and a receiver. The wireless test equipment may contain a call box that performs network-level testing by sending and receiving protocol-compliant network messages. The call box may transmit a radio-frequency test signal at a predetermined power. The antenna in the user equipment may receive the radio-frequency test signal and may provide the received radio-frequency test signal to the input of the receiver. The call box may send a network message such as a code-division-multiple-access intercode handover command to the user equipment to direct the user equipment to measure the received radio-frequency test signal power at the input of the receiver. The measured power may be transmitted to the call box as part of a pilot measurement message indicator, using an intercode handover command, or using other network messages.
A method for wirelessly obtaining a measured radio-frequency signal power at a receiver input in a wireless electronic device, comprising:
A method for using test equipment to perform over-the-air testing of user equipment with test equipment, wherein the user equipment has a receiver with a receiver input, comprising:
A method for performing over-the-air testing of user equipment using a code-division-multiple-access radio communications tester, comprising:
A method for performing over-the-air testing of user equipment using a radio communications tester, comprising:
