Abstract: Example test methods and apparatus are described. One example method includes receiving an uplink radio frequency signal by a test device from a terminal device, where the uplink radio frequency signal is generated by superimposing at least two test signals, and each of the at least two test signal corresponds to one communication protocol. The test device extracts the at least two test signals from the uplink radio frequency signal. The test device separately tests the at least two test signals, and obtains an uplink test result of the terminal device.

Abstract: The present invention discloses a signal output apparatus, a board, and a signal output method. UE signals to be output are grouped, and UE signals having similar powers are combined and are then output by using one same antenna. This resolves a problem that a low-power UE signal is distorted when a large quantity of UE signals are output from an air interface.
