Abstract

The present invention is an automatic testing system for a cellular phone module and a method thereof for automatically test a cellular phone module. The present invention includes a control computer having a graphic controlled program for providing a test request, wherein the graphic controlled program is written in Labview program, and a testing device electrically connected to the control computer and the cellular phone module for testing the cellular phone module in response to the testing request. The testing result is sent back to the control computer from the testing device right after the test is finished. Then the testing result is displayed via a graphic interface and stored in a text file and a graph file. The cellular phone module is determined to be good or not via the testing result.

Claims

1. A testing system for a cellular phone module, comprising:

a control computer having a graphic controlled program for providing a test request, wherein said graphic controlled program is written in Labview progra; and

a testing device electrically connected to said control computer and said cellular phone module for testing said cellular phone module in response to said testing request.

2. The testing system as claimed in claim 1, wherein said system comprises a power supply electrically connected to said cellular phone module for providing electricity.

3. The testing system as claimed in claim 1, wherein said testing device is a wireless communication tester.

4. The testing system as claimed in claim 1, wherein said testing device is electrically connected to said control computer via a GPIB cable.

5. The testing system as claimed in claim 1, wherein said testing device is electrically connected to said cellular phone module via a radio frequency cable.

6. The testing system as claimed in claim 1, wherein said control computer sends said test request to said testing device and then receives a testing result from said testing device, wherein said control computer further comprises a graphic interface for showing said testing results, wherein said testing result is stored in a text file and a graph file.

7. The testing system as claimed in claim 6, wherein said text file is an EXCEL file and said graph file is a JPG file.

8. The testing system as claimed in claim 6, wherein said graphic interface comprises a main displaying frame, a cursor function list and a graphic control list.

9. The testing system as claimed in claim 1, wherein said test request is one selected from a group consisting of a TX power test, a phase peak error test, a phase root mean square (phase RMS) test, a frequency error test, a power vs time test, an output radio frequency spectrum (ORFS) test, a sensitivity test and a RX level test.

10. The testing system as claimed in claim 9, wherein said output radio frequency spectrum (ORFS) test comprises a modulating spectrum test and a switching spectrum test.

11. The testing system as claimed in claim 9, wherein said RX level test comprises an input level sweep test and a frequency channel sweep test.

12. A method for testing a cellular phone module via a testing device and a control computer having a test request, comprising steps of:

(a) sending a test request from a control computer to said testing device;

(b) testing said cellular phone module in response to said test request via said testing device for obtaining a testing result;

(c) sending said testing result from said testing device to said graphic controlled program;

(d) displaying and saving said result via said graphic controlled program; and

(e) determining said cellular phone module is good or not via said result.

13. The testing system as claimed in claim 12, wherein said control computer comprises a graphic controlled program.

14. The testing system as claimed in claim 13, wherein said graphic controlled program is written in Labview program language.

15. The testing method claimed in claim 12, wherein said test request is one selected from a group consisting of a TX power test, phase peak error test, a phase root mean square (phase RMS) test, a frequency error test, a power vs time test, an output radio frequency spectrum (ORFS) test, a sensitivity test and a RX level test.

16. The testing method claimed in claim 15, wherein said output radio frequency spectrum (ORFS) test comprises a modulation frequency spectrum test and a switching frequency test.

17. The testing method as claimed in claim 15, wherein said RX level test comprises an input level sweep test and a channel sweep test.

18. The testing method as claimed in claim 12, wherein said testing device is a wireless communication tester.

19. The testing method as claimed in claim 12, wherein said graph interface comprises a main displaying frame, a cursor function list and a graph control list.

20. The testing method as claimed in claim 12, wherein said result is stored in a text file and a graph file.

21. The testing method as claimed in claim 20, wherein said text file is an EXCEL file and said graph file is a JPG file.
