Step S405, use industrial computer control program, the control program parameter file of load step S402,
Multisignal source system is initialized；
Step S406, opens coupling shielded box；
Step S407, after the non-signaling coupling procedure of handset starting MOS system to be measured, depends on mobile phone to be measured
Secondary fixed by respective second fixed mechanism；
Step S408, closes coupling shielded box；
Step S409, coupling shielded box cuts out, by light sensation, mobile phone to be measured learns that shielded box completely closes after,
Antenna coupling measurement is carried out according to the coupling measurement flow process of Project design；
Step S410, by coupling the timing function of shielded box, after timing T has arrived, coupling screen
Cover case to automatically open up；
Step S411, operator obtains the test result of mobile phone to be measured by the display on mobile phone UI interface；
If terminal test to be measured is passed through, just flow into next process as non-defective unit；If terminal test to be measured is not
Pass through, be just placed on defective products treatment region as defective products.
