The present application is described in further detail below with reference to the accompanying drawings and specific examples.

As shown in fig. 1, an embodiment of the present application provides a testing apparatus 100, which includes: the device under test 101, a support frame 102, a measuring antenna 103 and a vibration table 104. Wherein, the device under test 101 includes: an antenna to be tested 101 a; the equipment to be tested 101 is fixed on the vibration table 104; the support frame 102 is fixed on the vibration table 104, and the support frame 102 is fixed with the measurement antenna 103.

The device to be tested comprises an antenna to be tested, wherein the antenna to be tested can radiate signals by adopting low-frequency, high-frequency and 5G millimeter waves and the like.

The measuring antenna is used for receiving signals radiated by the antenna to be measured; the frequency band adopted by the measuring antenna is the same as that adopted by the antenna to be measured. Here, the measuring antenna is located within the radiation range of the antenna to be measured, and can receive the signal radiated by the measuring antenna.

Here, the antenna to be measured radiates a signal, the signal radiated by the antenna to be measured is received by the measuring antenna, and the signal received by the measuring antenna can represent the radiation performance of the antenna to be measured, such as power, Error Vector Magnitude (EVM), frequency Error and the like.

In the embodiment of the application, the condition that the measuring antenna receives the signal radiated by the antenna to be tested can be applied to a scene of testing the downlink index of the equipment to be tested.

In the embodiment of the application, the measuring antenna can also be used for sending signals to the equipment to be tested so as to control the equipment to be tested.

Here, the method can be applied to a scenario of testing an uplink index of a device under test in a case where the measurement antenna transmits a signal to the device under test.

In the embodiment of the application, the device to be tested may be subjected to ota (over the air) test. The OTA test is a method for testing wireless signals through an air interface, wherein the device to be tested and the test device are not connected by wires, but radiate and receive signals through a pair of antennas, wherein the pair of antennas may include: a transmit antenna and a receive antenna.

In this application embodiment, the equipment to be measured is fixed on the shaking table, and the support frame is fixed on the shaking table to it is fixed with measuring antenna, thereby can be so that the relative position of measuring antenna and equipment to be measured keeps unchangeable. When the vibrating table does not vibrate, the position of the antenna to be measured is unchanged, the position of the measuring antenna is also kept unchanged, and at the moment, the relative position between the antenna to be measured and the measuring antenna is kept unchanged. When the vibrating table vibrates, the position of the antenna to be measured changes, the support frame vibrates along with the vibration of the vibrating table, the measuring antenna vibrates along with the vibration of the support frame, at the moment, the displacement change of the antenna to be measured and the displacement change of the measuring antenna are kept synchronous, the angle change of the antenna to be measured and the angle change of the measuring antenna are kept synchronous, and at the moment, the relative position between the antenna to be measured and the measuring antenna is kept unchanged. In the case of vibration of the vibration table, the vibration table may vibrate horizontally or vertically, which is not limited in this embodiment of the present application.

In the embodiment of the present application, the vibration table may be an electromagnetic vibration table, and may also be another vibration table, which is not limited in this embodiment of the present application.

The testing device can be applied to testing environments for detecting the radiation performance of the antenna, such as a microwave darkroom, and the like.

In some embodiments, as shown in fig. 2, the device under test 101 may further include: a Remote Radio Unit (RRU) 101 b.

Here, when the device under test includes the Antenna under test and the RRU, the device under test may be regarded as an integrated device, that is, an Active Antenna Unit (AAU), such as: 5G millimeter wave AAU equipment.

In some embodiments, the support frame is configured to keep the measurement antenna and the device under test vibrating synchronously when the vibration table vibrates.

Here, since the device under test is fixed on the vibration table, in the case where the vibration table vibrates, the device under test fixed on the vibration table will vibrate simultaneously with the vibration table. Because the support frame is fixed with the measuring antenna and the support frame is fixed on the vibration table, the measuring antenna connected with the vibration table through the support frame can vibrate simultaneously with the vibration table under the condition that the vibration table vibrates. That is, in the case of vibration of the vibration table, the device under test, the measurement antenna and the vibration table will vibrate synchronously. Therefore, the device to be measured, the measuring antenna and the vibrating table vibrate synchronously, so that the influence of external vibration on the antenna to be measured can be eliminated. The influence of external vibration on the antenna to be tested is eliminated, so that when the reason for signal deterioration is judged, the vibration condition outside the equipment to be tested can be eliminated, the reason for signal deterioration can be determined to be caused by vibration of a module inside the equipment to be tested, and the performance of the antenna to be tested in a vibration environment can be accurately tested.

In some embodiments, the apparatus may further comprise: holding the pole; the equipment to be tested is fixed on the vibration table through the holding rod; the holding pole is fixed on the vibration table.

In one example, as shown in fig. 3, the device under test 101 is fixed on the vibration table 104 through a holding pole 301, and the holding pole 301 is fixed on the vibration table 104, wherein one end 301a of the holding pole 301 is fixed on the vibration table 104.

Here, the one end accessible screw fixation of embracing the pole is on the shaking table, and the equipment to be measured sets up on embracing the pole to can make the equipment to be measured fix on the shaking table through embracing the pole.

The holding pole can be made of a rigid metal material, wherein the metal material can be copper or silver, and the embodiment of the application is not limited to this.

In the embodiment of the present application, the height of the pole, the outer diameter of the pole and the wall thickness of the pole are not limited in the embodiment of the present application.

In some embodiments, the support frame is an L-shaped support, one end of the L-shaped support is fixed on the vibration table, and the other end of the L-shaped support is fixed with the measurement antenna.

In one example, as shown in fig. 4A, the support frame is an L-shaped bracket 401, one end 401a of the L-shaped bracket 401 is fixed on the vibration table 104, and the other end 401b of the L-shaped bracket 401 is fixed with the measurement antenna 103.

In another example, as shown in fig. 4B, the support frame is an L-shaped bracket 401, one end 401a of the L-shaped bracket 401 is fixed to the vibration table 104, and the other end 401B of the L-shaped bracket 401 is fixed to the measurement antenna 103.

In this embodiment, the supporting frame may be an I-shaped frame, one end of the I-shaped frame is fixed on the vibrating table, and the other end of the I-shaped frame is fixed with the measuring antenna.

In one example, as shown in fig. 4C, the support is an I-shaped bracket 401, one end 401a of the I-shaped bracket 401 is fixed on the vibration table 104, and the other end 401b of the I-shaped bracket 401 is fixed with the measurement antenna 103.

In some embodiments, the length of the horizontal rod of the L-shaped bracket is set based on the length D of the diagonal line of the device under test and the wavelength λ of the signal radiated by the antenna under test, and the horizontal rod is set along the horizontal direction of the measurement antenna and the device under test.

Here, the length L of the horizontal bar of the L-shaped bracket can be obtained by the following formula (1):

and D is the length of an oblique diagonal line of the equipment to be tested, and lambda is the wavelength of a signal radiated by the antenna to be tested.

Here, the length of the horizontal rod of the L-shaped bracket obtained by the above formula (1) can make the measuring antenna be located in the far-field region, so that the signal radiated by the antenna to be measured can be intuitively received. The far field region is a spherical surface with the position of the transmitting and receiving antenna as a focus and a linear path as an axis.

In the present embodiment, the horizontal bar of the L-shaped bracket may be as shown at 401c in fig. 4A.

In some embodiments, the material of the support frame is a rigid material.

Here, the support frame may be made of a rigid metal material.

In some embodiments, the height of the device under test relative to the vibration table and the height of the measurement antenna relative to the vibration table are equal.

Here, the height of the device under test with respect to the vibration table and the height of the measurement antenna with respect to the vibration table are equal, so that the measurement antenna can be made to better receive the signal radiated by the antenna under test included in the device under test.

In some embodiments, the apparatus further comprises: and the test equipment is used for detecting the signal received by the measuring antenna and determining the radiation index of the antenna to be tested.

Here, the radiation index may include: power, EVM, and frequency error.

The test device may be connected to the measurement antenna by a feeder.

In one example, as shown in fig. 5, test equipment 501 may be connected to measurement antenna 103 via feed line 502.

With the development of communication technologies, 5G is different from 2G and 4G, and 5G needs to satisfy more various service types and scenes, and in order to satisfy eight key performance indexes of three 5G scenes defined by the International Telecommunications Union (ITU), a 5G system needs to gradually face millimeter waves. The millimeter waves are mainly used for meeting the requirements of extremely high user experience rate and peak capacity of urban hotspots, suburban hotspots and indoor scenes. And 7, 3.7.7.7.7.8-5 GHz, 24.75-27.5GHz and 37-42.5GHz frequency bands of the Ministry of industry and correspondence develop 5G technical tests, and signals of 5G facing millimeter wave frequency bands are definitely released.

As the frequency increases, the cost of the connector and the feeder becomes higher and the size becomes smaller, and at the same time, the loss of the connector and the feeder becomes higher and higher. Against this background, the millimeter wave device integration design will gradually become the mainstream. The RRU and the antenna are directly integrated on the RRU without a connector and a feeder, so that the RRU and the antenna of the base station equipment are highly integrated. OTA testing has become the direction of evolution for future testing. Due to the integrated design of the antenna and the RRU, radio frequency signal transmission can not be carried out through the feeder, so that the OTA test under the vibration environment under the existing conditions can not be carried out at present.

The vibration test mainly inspects the stability of equipment indexes when the base station equipment has vibration with certain amplitude and frequency in the environment, and simulates the influence of the vibration on the equipment in the scene that vehicles pass through and the like after the base station equipment is installed in the transportation process. Active devices in base station equipment, especially crystal oscillator modules, have high sensitivity to vibration, and when a product is greatly influenced by external vibration, indexes such as frequency error and EVM (error frequency modulation) can be greatly deteriorated, so that the signal transmission quality is seriously reduced, and even communication cannot be performed.

In the related art, the operating frequency band of the base station device is low, for example: 2.6GHz and 3.5GHz, etc., as shown in fig. 6, RRU 1 and antenna 2 of the base station device are separately designed, and are connected by feeder 3.

The OTA test is performed for the antenna part. The antenna is placed in a microwave darkroom for testing gain, directional diagram and the like. The microwave darkroom is a high-precision device and has strict requirements on vibration, temperature, humidity and the like. As shown in fig. 7, in a microwave darkroom 1, an antenna 3 to be tested is tested by a measuring antenna 2, and the antenna 3 to be tested is rotated by a turntable system 4.

The vibration test is performed on the RRU, and a test system for performing the vibration test in the related art is shown in fig. 8. Vibration test installs equipment to be tested 1 on shaking table 3 through embracing pole 2, and the back is taken off to the antenna of equipment to be tested 1, is connected with test instrument (being test equipment) 5 through feeder 4. In conducting the vibration test, the variables of vibration include: vibration amplitude and vibration frequency, etc.

As can be seen from the above description, the OTA test and the vibration test in the related art are two independent tests, and the vibration test cannot be performed when the OTA test is performed. Because the vibration test is a vibration to RRU part and is connected with the instrument through the feeder line, the vibration test in the related technology is a conduction index instead of an OTA index. Here, the conduction index refers to an index transmitted through a feeder line, and the OTA index refers to a radiation index.

Since the RRU section and the antenna section in the current base station apparatus are separately designed, the OTA test and the vibration test in the related art can be separately performed.

In the 5G technology, the increase of the frequency band will result in the increase of the cost and the loss of the feeder line and the connector assembly connecting between the RRU and the antenna, and therefore, the RRU and the antenna in the 5G millimeter wave base station equipment are integrally designed, that is, the RRU and the antenna are not separately designed. The 5G millimeter wave base station device is shown in fig. 9.

Because the 5G millimeter wave base station is integrally designed, the OTA test and the vibration test cannot be separately carried out, and the OTA test and the vibration test can only be carried out by combining the OTA test and the vibration test. However, there is no test system and apparatus for testing by combining the OTA test and the vibration test in the related art.

The application provides a testing arrangement, can realize through this testing arrangement that millimeter wave equipment carries out the OTA test simultaneously under the vibration environment, has solved millimeter wave base station equipment and can't combine the difficulty together with OTA test and vibration test.

Because the index test of the millimeter wave equipment can be only carried out in a microwave darkroom in an OTA mode, and the vibration test can be only realized by placing the equipment on a vibration table, the OTA vibration test can be realized by combining the microwave darkroom and the vibration table.

When the OTA vibration test is carried out, each channel of the device forms a synthesized beam in a beam forming mode, and the beam has the characteristics of power, wave width, directivity and the like. In theory, the device is placed in a vibrating environment, and the beam characteristics are stable and invariant if the components of the device are able to effectively resist or compensate for the vibrations. However, the vibrating table has a certain horizontal displacement Δ X or vertical displacement Δ Z when vibrating, and after the equipment is mounted on the vibrating table through the holding pole, the whole equipment also generates a certain horizontal displacement Δ X or vertical displacement Δ Z. Since the signal measured by the fixed measuring antenna is also deteriorated due to the displacement of the device itself, it cannot be determined whether the deterioration of the signal is caused by the displacement of the device itself or the influence of vibration on the module inside the device.

To the testing arrangement that this application provided, this testing arrangement can combine shaking table and microwave darkroom, and the shaking table is placed in the darkroom, because the test of vibration environment more concerns the variable quantity of index, can simplify the design with original darkroom, replaces original revolving stage system for shaking table system. The test equipment is still installed on the shaking table through embracing the pole, and the height of embracing the pole depends on when vibrating to the requirement that the vibration is enlargied, and AAU generally requires not more than 2 meters apart from the bottom.

In order to overcome the interference of the displacement of the device itself on the test, the offset of this displacement is carried out by the use of L-shaped brackets. The existing darkroom test measurement antenna is directly fixed in the darkroom, the system measurement antenna is arranged on an L-shaped support, the L-shaped support is made of rigid materials, and the end of a vibration table is tightly and firmly fixed on the vibration table through screws. The horizontal displacement DeltaX or the vertical displacement DeltaZ generated by the equipment driven by the vibration table is 1:1 and is displayed on the L-shaped bracket and then displayed on the measuring antenna. The displacement of the vibration itself can be fully calibrated out. The measuring antenna is aligned with the center point of the device by a laser during testing.

The following explains the components included in the test apparatus provided in the present application:

simple microwave darkroom: the closed test space is used for testing the vibration environment, other test components are arranged in the darkroom, a wave-absorbing material needs to be pasted in the space, and the size of the space meets the size of a far field of the millimeter wave base station. Unlike the related art darkroom, the simplified darkroom does not require a turntable system.

A vibration table: and the vibration table is arranged in the simple microwave dark room, and because the weight and the volume of the millimeter wave base station are small, the electromagnetic vibration table with small specification parameters can be adopted. The vibration table can vibrate horizontally and vertically.

Holding a pole: the holding pole is fixed on the table top of the vibration table through screws, the holding pole is required to be stable and firm when being installed on the vibration table, and the equipment to be tested is installed on the holding pole through the hoop during testing. The holding pole is generally made of rigid metal materials. The height of the holding pole during the vibration test of the communication equipment is generally 2 meters, the outer diameter is 70mm, and the wall thickness is 5 mm.

An L-shaped bracket: the support is used for calibrating the displacement of the equipment during vibration, and is made of rigid metal materials, so that the displacement of the vibration can be completely calibrated. The horizontal end of the L-shaped support is stably and reliably arranged on the table top of the vibration table through a nut, and the vertical end of the L-shaped support is provided with a measuring antenna.

Measuring an antenna: the measuring antenna is used for transmitting or receiving signals, and when the downlink indicator of the equipment to be tested is tested, the measuring antenna receives the signals transmitted by the equipment to be tested and then sends the signals to the instrument through the rear feeder line; when the uplink index of the equipment to be tested is tested, the signal transmitted by the instrument is uploaded to the measuring antenna through the feeder, then the signal is transmitted to the equipment to be tested through the measuring antenna, and the equipment to be tested receives the signal of the measuring antenna.

Testing the instrument: and testing the indexes of the equipment to be tested. Here, the device under test index may include: radiation indexes such as power, EVM and frequency error.

The application provides a testing arrangement can replace the darkroom revolving stage through the shaking table, combines vibration environment and darkroom to adopt the unable test that the displacement of L shape rigid bracket calibration vibration itself brought or survey inaccurate problem.

The application provides a testing arrangement who carries out OTA test under the vibration condition, can realize carrying out the OTA test under the vibration environment of millimeter wave basic station equipment through this testing arrangement, solved future millimeter wave basic station equipment and can't combine the difficulty together with OTA test and vibration environment. The millimeter wave base station equipment has an effective evaluation scheme under severe environments such as vibration. The OTA test under the vibration environment of the 5G millimeter wave integrated base station equipment is solved, and the OTA test under the vibration environment of the equipment which can not be connected through a radio frequency feeder line can be used, and similar products such as an antenna, a radar and the like can be realized.
