Description

A kind of wireless performance method of testing of wireless product
Technical field
The present invention relates to moving communicating field, relate in particular to a kind of wireless performance method of testing of wireless product.
Background technology
A lot of wireless products of producing on Vehicles Collected from Market have all adopted plate to carry antenna scheme, as familiar wireless network card, wireless router etc., and when the wireless product that plate is carried to antenna carries out the production test of wireless performance.When test, be mainly to utilize RF testing equipment to test the signal strength signal intensity of RF link.For preventing that plate carries antenna itself signal of RF link is disturbed, during test, need to disconnect RF link and plate carries antenna.Mainly be divided at present three kinds of method of testings:
Method one: as depicted in figs. 1 and 2, making needs to connect by a wireless test seat between its RF link of wireless product in this way and antenna, when test wireless performance, also needs just can test by buckling the cable line matching with wireless test seat.The operation principle of the wireless test seat that this method of testing is used is, the inside of test bench is communicated with under normal circumstances, and RF link and antenna are normal connections, after buckling the cable line matching with it, will disconnect the connection with antenna.Although it is very convenient to use this method of testing to carry out production test, for such a wireless test seat, on market, generally will not sell for 1 to 2 yuan not etc., and the cable line matching is with it also expensive much than normal p-wire.
Method two: because the testing cost of method one is higher, in order to reduce production test cost, as shown in Figure 3 and Figure 4, be that product is when design, first between RF link and antenna, design an electronic component and carry out bridge joint, as 0 common Ohmic resistance, at the front end of electronic component, beat via hole and to the back side of pcb board, carry out the test of wireless performance simultaneously.Before this method requirement test, first disconnect the electronic component that RF link and antenna carry out bridge joint, after to be tested completing, again RF link and antenna are coupled together.Because this method of testing need to be beaten via hole, and wireless signal is having 1 to the decay of 2db not etc. after via hole, causes final test result not accurate enough.
Method three: in order to improve the accuracy of wireless test result, so derived again other a kind of method of testing on the basis of method two, as shown in Figure 5 and Figure 6, before test, same RF link need to first disconnect and being connected and making RF link connection hold and test to wireless test point of antenna, after the wireless performance of complete veneer to be tested, antenna and RF link connection is got up again.The plate of producing in the market carries the wireless product of antenna, for the common practice of this method of testing, be all by first disconnecting being connected and passing through an electronic component of RF link and antenna before test, as the resistance of 0 ohm jumps between RF link and wireless test point, after complete wireless performance to be tested, again electronic component is welded and gets off to jump to RF link and antenna end couples together it.For this method of testing, although improved the accuracy of test result, test gets up production efficiency is had a great impact, and resistance is also easy to damage in the process of repeated disassembled and assembled welding, has greatly improved production test cost.In addition, under this method, because electronic device needs multiple welding in test process, also can affect device property, cause radio-frequency (RF) index inconsequent.
Summary of the invention
In order to solve the problems referred to above of prior art, be necessary to provide the wireless performance method of testing of the wireless product of the low and reliable test result of a kind of testing cost.
The technical scheme that technical solution problem of the present invention provides is:
A wireless performance method of testing for wireless product, the circuit board of described wireless product comprises that wireless chip, RF link and plate carry antenna, it is characterized in that comprising,
Step S1: a kind of testing jig that carries antenna and test antenna for fixed head is provided;
Step S2: test product and RF test antenna are fixed on testing jig, and holding plate carries the relative position of antenna and RF test antenna;
Step S3: the signal strength signal intensity that adopts RF testing equipment to receive RF test antenna is tested.
Wherein, described plate carries antenna and parallel being oppositely arranged of described RF test antenna.
Wherein, described testing jig comprises the first fixed part of fixing test product and fixing the second fixed part of RF test antenna, and the position of described the first fixed part and the second fixed part is parallel and be oppositely arranged.
Wherein, to carry antenna corresponding with the specification of RF test antenna for described plate.
Compared with prior art, the wireless performance method of testing of wireless product of the present invention adopts RF test antenna to receive the signal of the antenna transmission of test product, the signal strength signal intensity receiving by RF test antenna judges whether the signal strength signal intensity of RF link meets the requirements, on RF link, do not need to increase test bench and increase bridge joint components and parts, before test, do not need SMT welding resistance yet, after test OK, do not need dismounting resistance yet, can not cause resistance to damage risk in repeated disassembled and assembled process, do not exist device to affect device property risk because of multiple welding yet, more can not cause the bad probability of product because of artificial welding after test OK, can not cause radio-frequency (RF) index inconsequent, improved the accuracy of test, also improved production efficiency, reduce production costs simultaneously.
