The framework of WLAN RF index automatic test system proposed by the invention as shown in Figure 1, it (can be the WLAN network interface card by main control computer 1, RS232 serial port adapter 2, equipment under test 3, module, access point even Wireless ADSL), composition such as Agilent E8408 signal analyzer 4, Agilent E4438 signal source 5, Agilent E4404 spectrum analyzer 6, the E4418 of Hewlett-Packard power meter 7, general barcode scanner 8; Wherein, IEEE488 bus adapter and driver thereof are installed on the main control computer 1, and the IEEE488 bus cable by standard is connected with testers such as Agilent E8408 signal analyzer 4, Agilent E4438 signal source 5, Agilent E4404 spectrum analyzer 6, the E4418 of Hewlett-Packard power meter 7 are parallel respectively, and each instrument disposes different addresses respectively and is convenient to host addressing; Main control computer 1 is connected with the RS232 adapter by serial port DB-9 simultaneously.And and then be connected with the serial port of tested machine. operate in main program on main control computer operation and the read test data by total each tester of line traffic control of IEEE488 and compare to analyze and form and judge; Main control computer 1 is is also read and write the related register of equipment under test 3 by serial ports, controls its operating state; Main control computer 1 is gone back the control strip code scanner simultaneously and is read corresponding product bar code, is convenient to form corresponding relational database.
Software of the present invention is overall to be constituted as shown in Figure 2, mainly (comprising: the RS232 drive software by bottom layer driving software, the IEEE488 drive software, barcode scanner drive software and other relevant PC drive softwares etc.), operating system (application software of the present invention runs on the Windows operating system of standard), each application software (comprises the bar code scan application software, the sensitivity test application software, the power test application software, the waveform analysis application software, the testing throughput application software, database generates application software etc.) and formation such as user interface, maintenance/upgrading or transplanting are convenient in each module hierarchical block design.The soft ware autonomous programming of various application software modules for being correlated with at the present invention, remainder is the Windows operating system of standard or the driver that related standards equipment carries.
Among the present invention, the testing software that runs on main control computer can directly carry out commands for controlling to each tester, replace the panel button operation, can the read test data replace manually reading by the IEEE488 bus simultaneously, and according to the specification thresholding formation judgement of importing, the result informs the tester intuitively with the form of PASS/FAIL. each test event has satisfied the basic demand of WLAN (wireless local area network) production test event basically.
Among the present invention, adopt incorporate design, the tester that it is separate with all, programmable attenuator and equipment under test are set up into an organic Auto-Test System, by software programming each separate test event is organized in the Auto-Test System simultaneously, can under situation about switching, finishes the automatic test of all items without any need for artificial hardware.
Function of the present invention mainly contains: sensitivity minimization test and judgement; The maximum power test is judged with index; Testing throughput and judgement; Transmitted waveform is analyzed and is judged (mainly judging the level difference of main lobe and secondary lobe); Bar code scan is also set up the correspondence database of bar code and test result and conclusion automatically; The PASS/FAIL of demonstration directly perceived gives the operator.
