Problems solved by technology

The disadvantage of this calibration method is: if the convergence method of performance parameter value calibration is not suitable, then the calibration will take a long time; for example, the power calibration of the power amplifier of the mobile phone motherboard, different power amplifier types, the calibration time varies greatly , the reason for the large difference in calibration time is that the law of power growth of different power amplifiers is different, some satisfy

Embodiment Construction

[0014] Below in conjunction with accompanying drawing, further illustrate how the present invention is realized:

[0015] The invention discloses a method for quickly calibrating performance parameters of a mainboard of a mobile phone. First write the quick calibration program; then start the quick calibration program, configure the test parameters of the test instrument and configure the voltage and current of the controllable power supply through the GPIB remote control command, configure the performance parameter test environment of the mobile phone motherboard through the USB serial port line; finally control the mobile phone through the quick calibration program The mainboard starts to communicate with the test instrument, and reads the initial test value of the mainboard performance parameters from the test instrument, and uses the fast calibration algorithm to find the appropriate calibration value of the appropriate mobile phone mainboard performance parameters.

Abstract

The invention discloses a mobile phone main board performance parameter quick-calibration method, which comprises the following steps of: firstly, running a quick calibration program, and automatically configuring the testing environment of a testing instrument and a controllable power supply by using a general purpose interface bus (GPIB) cable; secondly, automatically controlling a mobile phonemain board to enter a test mode by using a universal serial bus (USB) serial cable, and automatically configuring a mobile phone main board performance parameter testing environment by using the USB serial cable; and finally, reading an initial main board performance parameter test value from the testing instrument, automatically dynamically regulating a, upper temporary bound and a lower temporary bound in a calibration process, and quickly searching a proper calibration value of a mobile phone main board performance parameter out from a relatively smaller range. In the quick calibration method, effects are more and more remarkable along with the increasing of number of main boards to be calibrated. Compared with the conventional calibration methods, the invention optimizes a performanceparameter calibration algorithm and shortens performance parameter calibration time.

Description

technical field [0001] The invention relates to the technical field of performance parameter calibration, in particular to performance parameter calibration applied to mobile phone motherboards. Background technique [0002] The traditional method of calibrating the performance parameters of the mobile phone motherboard is generally based on the calibration of the given default performance parameter values ​​until the calibration results of the performance parameter values ​​meet the given conditions. The disadvantage of this calibration method is: if the convergence method of performance parameter value calibration is not suitable, then the calibration will take a long time; for example, the power calibration of the power amplifier of the mobile phone motherboard, different power amplifier types, the calibration time varies greatly , the reason for the large difference in calibration time is that the law of power growth of different power amplifiers is different, some satis...
