starting a test program and displaying at least one option allowing the test program to be tested, wherein the at least one option comprises an ACLR option;
and testing the ACLR of the mobile terminal through the test program when the ACLR option is detected to be selected.
4. The method according to any of claims 1-3, wherein after said selecting a target Ecomp from said plurality of Ecomps, the method further comprises: and performing ET calibration on the mobile terminal based on the target Ecomp.
5. The method according to any of claims 1-3, wherein after said selecting a target Ecomp from said plurality of Ecomps, the method further comprises:
acquiring target Ecomps of a plurality of mobile terminals, wherein the target Ecomps of the plurality of mobile terminals are determined based on the envelope compression point determination method;
and taking an average value of the target Ecomps of the plurality of mobile terminals, and performing ET calibration on all the mobile terminals based on the average value.
6. An envelope compression point determining apparatus, comprising:
a setting unit for setting an envelope tracking compression point Ecomp;
the calibration unit is used for carrying out the ET calibration on the envelope tracking of the mobile terminal based on the set Ecomp;
the restarting unit is used for restarting the mobile terminal after the ET is calibrated;
a testing unit for testing the adjacent channel leakage ratio ACLR of the mobile terminal;
the recording unit is used for performing associated recording on the ACLR and the current power consumption of the mobile terminal; the setting unit is further used for resetting the Ecomp when the ACLR is smaller than the set ACLR, and the reset Ecomp is equal to the sum of the Ecomp set last time and a set value; the calibration unit is also used for executing the step of ET calibration on the mobile terminal based on the set Ecomp;
an obtaining unit, configured to obtain multiple ecomps for performing ET calibration on the mobile terminal when the ACLR is greater than or equal to a set ACLR, where ACLRs corresponding to the multiple ecomps are all smaller than the set ACLR;
and the selecting unit is used for selecting a target Ecomp from the Ecomps, and the power consumption of the mobile terminal is minimum under the target Ecomp.
7. An envelope compression point determination apparatus comprising a processor, a memory, a communication interface, and one or more programs stored in the memory and configured to be executed by the processor, the programs comprising instructions for performing the steps in the method of any of claims 1-5.
8. A computer-readable storage medium, characterized in that a computer program for electronic data exchange is stored, wherein the computer program causes a computer to perform the method according to any one of claims 1-5.
