Synchronous measurement method for total radiation power (TRP) of cell phone

The invention relates to a synchronous measurement method for the total radiation power (TRP) of a cell phone, belonging to the technical field of radio-frequency testing of wireless communication products. The method comprises the following steps of: calibration: calculating a calibration conversion factor Fj according to power Pin of a signal transmitted by a transmitting antenna (4) arranged in an over-mode resonance cavity and the measured power for a receiving antenna to receive a signal transmitted by the transmitting antenna (4); and measurement: solving the TRP of the cell phone to be tested according to the power of the receiving antenna arranged in the over-mode resonance cavity for receiving a signal transmitted by the cell phone to be tested and the calibration conversion factor Fj, wherein during measurement, the transmitting antenna (4) is shift out of a shielding room, and the cell phone to be tested in arranged at a position of the transmitting antenna (4). The synchronous measurement method provided by the invention is high in testing precision and convenient to operate.
