Improve the technical indicator of antenna.And the antenna of high target requirement is designed, not only need to be grasped modern antenna design theory and design
Method, it is also necessary to have advanced test equipment and means of testing, theoretical validation or performance indicator are carried out to designed antenna
Test.Test table is an important tool in Antenna testing system.With the development of microwave technology, wireless product form
Also more and more diversified with usage scenario, antenna setting form is also more and more.For the OTA of traditional transmission V belt translation
Test table, due to reasons in structure, cable arrangement is complicated, and test function is single, and once-through operation can only test a test point
Data need to manually adjust switching aerial position to carry out next group of parameter testing during entire test period, so that operation is multiple
It is miscellaneous, time-consuming.The aging of artificial simultaneously intervention and synchronous belt makes positioning accuracy low, does not adapt to automatic test demand,
And can not achieve automatic monitoring, programming count and performance optimization and upgrading, it is not able to satisfy wanting for antenna technology index test increasingly
It asks.
Summary of the invention
The purpose of the invention patent is to provide a kind of novel positioning turntable of OTA test, passes through the orderly rotation of five axis
Or translation, center that Devices to test can polarize are adjusted to the spatial position limited, realize device under test radiation characteristic and reception
Characteristic test positioning, improves wireless device test efficiency, while also improving the integration test ability of antenna setting, passes through height
The positioning of precision improves the reliability of test data.Turntable motion control and status monitoring are by the computer of control unit and dedicated
Software is completed, and software realizes real-time monitoring to each shaft position of turntable, and can specify turntable motion profile according to existing sound demand is tested, into
The various adaptation operations of row, simplify multi-antenna antenna measurement process.The upgrading of software can also further promote test macro
Performance and measuring accuracy.
(1) technical solution
The novel positioning turntable of OTA test described in the invention patent, by liftable pedestal, horizontal displacement platform, polarization
Turntable and control unit composition.Horizontal displacement platform includes X-axis, Y-axis, and the lifting with pedestal realizes Devices to test along X, Y, Z tri-
The translation in a direction positions.The turntable that polarizes includes horizontal polarization axis and vertical polarization axis.Horizontal polarization axis is for adjusting to be measured set
Standby azimuth, to complete the sampling of each point in a great circle, vertical polarization axis is used to adjust the polarisation angles of Devices to test, with
The switching of different great circles to be measured is realized, to meet the cycle tests requirement to location.
