The invention provides a method, a system and a device, which are used for adjusting the launching power at the communication terminate; the method includes: procedure A, the to-be adjusted communication terminate is communicated with the main control machine after starting; procedure B, the main control machine is primarily synchronized with the to-be adjusted communication terminate, after that, the main control machine sends the adjusting and collocating message and start launching order to the communication terminate; procedure C, the communication terminate launches a plurality of signals which are detected at the up-link time slot; procedure D, when the communication terminate finishes the pluralities of signal launch, the main control machine works out the power launching adjustingchart fro every communication terminate according to the corresponding data of the signal launch, the chart is then sent to the corresponding communication terminate. The invention can realize the adjustment of a plurality of communication terminates, full increasing the utilization rate of device; therefore, the invention is applicable in the mass production of terminate.
Description
technical field [0001] The present invention relates to a technology for detecting a communication terminal, in particular to a method, system and device for calibrating the transmission power of a communication terminal. Background technique [0002] Due to the differences in the individual characteristics of communication terminal transmitters and RF power amplifiers and other devices, different communication terminals have large differences in transmission power before calibration, which usually cannot meet the requirements of the 3GPP protocol for communication terminal transmission power. Calibrate the output power of the communication terminal to meet the requirements of the specification. [0003] The structure of the communication terminal transmitter is shown in Figure 1. The I and Q signals output by the digital baseband are input to the modulator after passing through the digital-to-analog converter, and the modulated RF signal is input to the input terminal of th...
