The technical solution of the radio frequency testing method of the present application will be further described in detail through several embodiments.
The first embodiment is as follows:
please refer to fig. 1, which is a flowchart illustrating a radio frequency testing method according to an embodiment of the present application, wherein the method is suitable for a scenario where a mobile terminal performs a radio frequency test at different positions inside a test box, and one test antenna is connected to the mobile terminal. Specifically, the method comprises the following steps:
step S101: providing a mobile terminal to be tested in a test box.
Specifically, in this step, the step of placing the mobile terminal to be tested into the test box may be performed manually by a tester, or the tester may control a transmission device to accurately transmit the mobile terminal to be tested into the test box.
It should be noted that the mobile terminal to be tested may be a mobile communication device such as a mobile phone, a tablet computer, a smart watch, and AR glasses. The test box may be a radio frequency shielding box, which is a metal body that uses various shapes of shields made of conductive or magnetic conductive materials to limit electromagnetic capability within a certain spatial range and suppress radiation interference. And the conduction and the radiation are processed to realize the equipment for providing an interference-free testing environment for the tested wireless communication equipment. The radio frequency shielding box can be designed to be in mechanical connection with a conveying device, a tester can remotely control the conveying device to convey a product to be tested to the interior of the radio frequency shielding box and convey the tested product to the exterior of the radio frequency shielding box, so that potential damage of electromagnetic wave radiation generated in a radio frequency testing process to the tester can be avoided, and influence of inevitable errors in manual operation on consistency of testing conditions among products can also be avoided. It will be appreciated that the conveyor may be a conveyor belt or a robotic arm.
Step S102: and executing a plurality of radio frequency tests on the mobile terminal.
Specifically, in this step, a movable support may be designed inside the test box, the mobile terminal to be tested is placed on the movable support, and the relative position relationship between the internal antenna of the mobile terminal to be tested and the test antenna inside the test box is changed by controlling the movement or the overturning of the movable support, where it is to be noted that a fixed position test antenna is arranged inside the test box. Further, each time the relative position of the mobile terminal to be tested and the test antenna is changed, the mobile terminal to be tested is subjected to a radio frequency test, and corresponding test data is obtained, which may specifically be a radio frequency power value. It can be understood that, during the testing process, the relative position relationship between the mobile terminal to be tested and the testing antenna should be clearly recorded and stored, and it is ensured that other mobile terminals to be tested are tested under the same conditions, so as to ensure the consistency of the radio frequency testing conditions of the mobile terminals. Meanwhile, the specific test times and the relative positions of the mobile terminal and the test antenna in each test can be selected according to the characteristics of the specific tested product, and the limitation is not too much.
Those skilled in the art will appreciate that the radio frequency test includes a radio frequency transmission test and a radio frequency reception test, wherein the radio frequency transmission test is: the method comprises the steps that a radio frequency transmitting module of the mobile terminal transmits a first radio frequency signal to a testing antenna inside a testing box, the testing antenna transmits the first radio frequency signal to a testing instrument outside the testing box, the testing instrument obtains performance parameters of the transmitting module of the mobile terminal when the radio frequency signal is transmitted, and the performance parameters comprise a transmitted radio frequency power value and the like. The radio frequency receiving test is as follows: the test instrument transmits a second radio frequency signal to the test antenna, the test antenna forwards the second radio frequency signal to the radio frequency receiving module of the mobile terminal, and the test instrument acquires performance parameters of the radio frequency receiving module of the mobile terminal when receiving the radio frequency signal, wherein the performance parameters comprise a received radio frequency power value and the like.
Step S103: and obtaining the radio frequency power value of the corresponding radio frequency signal based on the plurality of radio frequency tests.
Specifically, in this step, the test meter can obtain radio frequency performance parameters of the mobile terminal when transmitting radio frequency signals or receiving radio frequency signals, where the radio frequency performance parameters may include frequency spectral density, radio frequency power value, center frequency value, and the like. Therefore, according to the foregoing, the test instrument can obtain the radio frequency power value corresponding to each radio frequency test every time the relative position of the mobile terminal to be tested and the test antenna is changed.
It will be appreciated that during the course of testing, the test results corresponding to each test are clearly recorded and stored for subsequent statistical processing.
Step S104: and carrying out statistical calculation processing on the obtained multiple radio frequency power values to obtain a comprehensive power value of the mobile terminal.
Specifically, in this step, a plurality of radio frequency power values are obtained through the foregoing radio frequency tests of the mobile terminal to be tested, and the obtained plurality of radio frequency power values need to be analyzed in order to feed back the antenna performance of the mobile terminal to be tested. In the embodiment of the present application, the rf power values are analyzed by arithmetic mean, wherein the obtained rf power values are summed and divided by their numbers to obtain a simple arithmetic mean, which is the integrated power value. In addition, in other embodiments, a standard power value may be obtained first, the obtained multiple radio frequency power values are compared with the standard power value respectively to determine a weighting factor of each radio frequency power value, and the obtained multiple radio frequency power values are weighted and calculated based on the weighting factor corresponding to each radio frequency power value to obtain the integrated power value.
The weighting factor, i.e., the weight, may reflect the importance of a data in a data set, and is generally expressed by a weight. And multiplying each data in the data set by corresponding weight, then adding the sum and dividing the sum by the sum of the weights to obtain the weighted arithmetic mean of the data set.
Further, the method for determining the weighting factor of each rf power value in the embodiment of the present application compares the obtained test result with the standard power value, and the closer the value is to the standard power value, the more the test result can feed back the real state of the antenna performance of the mobile terminal to be tested, so the weighting factor, i.e. the weight, of the test result should be set to be larger, thereby ensuring the accuracy of the final result, i.e. the integrated power value.
It will be appreciated by those skilled in the art that the standard power value acquisition method can be achieved by means of a dedicated radio frequency test instrument.
Step S105: and judging whether the comprehensive power value of the mobile terminal exceeds a preset range of a standard power value.
Specifically, in this step, the integrated power value obtained by the above calculation is compared with the standard power value to determine whether the antenna performance of the mobile terminal to be tested reaches the standard. The method is mainly suitable for testing the antenna performance of the mobile terminal before leaving a factory, and is generally used for testing batch products. Therefore, under the condition of ensuring the accuracy of the test result, a simple test instrument is usually adopted to improve the test efficiency and the test cost, so that the obtained comprehensive power value is lower than the standard power value. Therefore, an allowable range is preset based on the standard power value, and the comparison with the standard power value is to compare the obtained integrated power value with the allowable range of the standard power value.
Step S106: and when the comprehensive power value is judged not to exceed the preset range of the standard power value, determining that the radio frequency test of the mobile terminal is qualified.
Specifically, in this step, the obtained integrated power value is compared with the range allowed by the standard power value: if the comprehensive power value does not exceed the allowable range of the standard power value, determining that the radio frequency test of the mobile terminal to be tested is qualified; and if the comprehensive power value exceeds the range allowed by the standard power value, determining that the radio frequency test of the tested mobile terminal is unqualified.
Thus, the radio frequency test method provided by the embodiment of the application is completed.
Example two:
please refer to fig. 2, which is a flowchart illustrating a radio frequency testing method according to a second embodiment of the present application, where the method is suitable for a scenario where a corresponding radio frequency test is performed according to multiple test antennas disposed at different positions of a test box, where the multiple test antennas are all connected to a mobile terminal. It should be noted that the radio frequency testing method provided in the second embodiment of the present application is further optimized by "performing multiple radio frequency tests on the mobile terminal" in step 102 on the basis of the technical solution provided in the first embodiment, and therefore steps the same as or corresponding to those in the foregoing embodiments are not described herein again. Specifically, the method comprises the following steps:
step S201: providing a mobile terminal to be tested in a test box.
Step S202: and executing a plurality of radio frequency tests on the mobile terminal.
Specifically, in this step, the mobile terminal to be tested is placed on a movable support, and in this step, the position of the mobile terminal to be tested may be fixed. Furthermore, a plurality of test antennas are arranged at different positions inside the test box, one end of each test antenna is connected with the mobile terminal to be tested, the other end of each test antenna is connected with a switch, and the switches connected with the plurality of test antennas are connected with the test instrument through a bus. In the process of executing multiple radio frequency tests, the test antennas at different positions are controlled to be in a working state through the change-over switch, and the mobile terminal to be tested is tested based on the test antennas at different positions to obtain corresponding test results. Further, the sequence of switches and the results obtained from each test are clearly recorded and stored for subsequent statistical processing. It can be understood that, in the process of performing multiple radio frequency tests on the mobile terminal, compared with the operation of changing the position state of the mobile terminal, performing multiple radio frequency tests through the switch can reduce the test error between different mobile terminals. Similarly, the number of the specific test antennas in the test box can be selected according to the characteristics of the specific product to be tested, and is not limited too much here.
Step S203: and obtaining the radio frequency power value of the corresponding radio frequency signal based on the plurality of radio frequency tests.
Step S204: and carrying out statistical calculation processing on the obtained multiple radio frequency power values to obtain a comprehensive power value of the mobile terminal.

Step S206: and when the comprehensive power value is judged not to exceed the preset range of the standard power value, determining that the radio frequency test of the mobile terminal is qualified.
So far, the radio frequency test method provided by the second embodiment of the present application is completed.
According to the radio frequency test method provided by the embodiment of the application, radio frequency tests are carried out on the same mobile terminal for multiple times by changing the relative position relationship between the mobile terminal to be tested and the test antenna, weighted average processing is carried out on a plurality of obtained radio frequency power values to obtain a comprehensive power value of the radio frequency tests, and then the comprehensive power value is compared with a standard power value to determine whether the antenna performance of the mobile terminal to be tested is qualified. By adopting the radio frequency test method of the embodiment of the application, the accuracy of the radio frequency test result of the mobile terminal can be improved so as to reflect the real performance of the built-in antenna of the mobile terminal, and meanwhile, the influence of manual errors on the consistency of test conditions among different mobile terminals can be reduced.
