Embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is described.

As depicted in figs. 1 and 2, the utility model provides a kind of USB interface-based wireless network card testing apparatus, and this device is made up of a USB connector, E2PROM memory, host computer, data transaction controller, a PCI socket, a miniPCI socket, a PCMCIA socket, radio frequency testing instrument.

Wherein, 30 is USB connector, be the interface that data transaction controller 31 is connected to host computer 1, the test driver that is based on USB interface and the application program of the operation of host computer end finish that the function that radio frequency testing instrument 2 and wireless network card test mode and result show being set.The USB2.0 standard of the complete compatibility standard of USB interface.

For the test of compatible multiple interfaces network interface card, designed three kinds of sockets in the interface adapter 3, be respectively PCI socket 34, miniPCI socket 35, PCMCIA socket 36, can insert PCI, miniPCI, the Cardbus interface shape wireless network card of standard.Because wireless network card mostly is the 3.3V system, so the PCI socket only provides the 3.3V power supply, compatible 3.3V/5V bus signals.In order to strengthen versatility, the pci interface signal is directly connected to miniPCI and PCMCIA socket.

32 is power regulator, and the 5V power source conversion that outside pressurizer is imported is a 3.3V voltage, is separately the power supply of PCI, miniPCI and PCMCIA socket.The GPIO signal of data transaction controller 31 is connected to the Enable Pin of power regulator 32, controls powering on/power operation of wireless network card.

The 33rd, E ²Prom memory is used to store the start-up routine of data transaction controller 31, is connected with data transaction controller 31 by the SPI interface signal.

2 is the rf integration test instrumentation, and the test program of host computer 1 operation is provided with state informations such as test data type, test parameter index and step-length by the state that transmits and receives of main frame LAN mouth control rf integration test instrumentation.

Be example with the test of miniPCI network interface card below, describe method of testing of the present utility model.

As shown in Figure 2, connect tester 2 to host computer 1, start tester by the LAN mouth.MiniPCI network interface card 5 is inserted miniPCI sockets 35, connect the extended line of USB connector 30 and insert the USB socket of host computer 1, at last the radio frequency testing mouth of miniPCI network interface card 5 is connected to the emission or the receiving port of tester 2 by coaxial cable.When needing to change network interface card, the radio frequency testing mouth that only coaxial cable of tester 2 need be connected to new network interface card gets final product, and other connecting lines do not need to change, and connected mode is very easy.

Each module connecting line is connected the back power on, and start test program to system.Flexible and convenient for what test, can emission or accepting state and test event directly be set by the test program interface.Test program is provided with the test mode and the parameter of tester 2 on the one hand by the LAN mouth of host computer 1, the test mode and the data of network interface card are set by USB interface and data transaction controller on the other hand.

Whether test program starts back ejection dialog box inquiry network interface card ready, this dialog box also can eject after the test item of every network interface card is all finished, at this moment need the tester will be the survey grid card extract and classify according to test result, the network interface card to be measured that more renews, connect the radio frequency testing mouth of coaxial cable to network interface card to be measured, confirm in the dialog box of host computer 1 after finishing that network interface card is ready, main frame just can be by the GPIO signal of USB interface control data switching controller 31, make the Enable Pin of power regulator 32 effective, for miniPCI socket 35 and 5 power supplies of miniPCI network interface card, realize the hot plug test of miniPCI network interface card.

Tester 2 began test after test mode and parameter setting were finished, and the result of each test item can be presented at main frame interface, for example physical layer such as transmitting power and receiving sensitivity index in detail.Can judge automatically by test result whether this network interface card belongs to qualified product.The GPIO signal of host computer 1 control data switching controller 31 after test is finished, the Enable Pin of power regulator 32 is forbidden, at this moment miniPCI socket 35 and miniPCI network interface card 5 are in off-position, can directly change the miniPCI network interface card, have greatly improved test speed.

Here be example only with the miniPCI network interface card, being connected of PCI and Cardbus interface network interface card is consistent therewith with method of testing, simplified the exploitation and the maintenance of host side test program, make same test program can compatible USB, PCI, the test of miniPCI, Cardbus interface network interface card.And the utility model is simple in structure, and cost is lower, and very high practical value is arranged.
