Problems solved by technology

At present, general SMT factories use special comprehensive testers in the production test of WIMAX and WIFI mobile terminals, such as Agilent's 8300A (WIMAX non-signaling comprehensive tester) and Agilent's N4010 (WIFI non-signaling comprehensive tester) ), but the price of this kind of meter is high, and the reusability of this kind of meter is relatively poor, which causes the production cost of this kind of terminal to increase greatly and the waste of resources, thus pushing up the market price of this kind of product

Embodiment Construction

[0011] As shown in Figure 1, connect the DUT to the PC under test via a USB Cable, and use the test application program on the PC to control the DUT. GPIB line connection, used to control the instrument to read the power value in the specified frequency band test. When the DUT is ready, start the test program, control the DUT to transmit at the rated power, and then initialize the meter to read the power. Note that when testing WIMAX, it is best to turn off WIFI transmission, so as not to affect the measured value of WIMAX due to WIFI transmission.

Abstract

The invention discloses a WIMAX (worldwide interoperability for microwave access) and WIFI (wireless fidelity) coupling test method. A DUT(device under test) is connected with a testing PC (personal computer) through a USB (universal serial bus) cable so that a test application program on the PC can be used for controlling the DUT, a frequency spectrum analyzer is connected with a coupling antenna board through a radiofrequency cable, and the frequency spectrum analyzer is connected with the PC through a GPIB(general purpose interface bus) and used for controlling an instrument to read power value within the specified frequency band. The test method includes of starting a test program to control the DUT to transmit in rated power after the DUT is prepared, initializing the instrument and then reading the power. The test method is simple and feasible in implement reduces test cost and improves test efficiency in production of the like terminal products greatly, and accordingly the like terminal products have higher competitiveness in market prices.

Description

technical field [0001] The invention relates to the production test field of mobile communication products, in particular to a WIMAX and WIFI coupling test method. Background technique [0002] With the development of mobile communication technology, there are higher requirements for the performance and quality of mobile communication products, which correspondingly pose challenges to the manufacturing technology of mobile communication products; at the same time, in the face of increasingly fierce competition, it is necessary to improve production efficiency, Reducing production costs is a long-term challenge for every processing plant and customer. At present, general SMT factories use special comprehensive testers in the production test of WIMAX and WIFI mobile terminals, such as Agilent's 8300A (WIMAX non-signaling comprehensive tester) and Agilent's N4010 (WIFI non-signaling comprehensive tester) ), but the price of this kind of meter is high, and the reusability of th...
