Detailed Description
Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present application and should not be construed as limiting the present application.
Isolation testing systems and methods of embodiments of the present application are described below with reference to the accompanying drawings.
Fig. 1 is a schematic structural diagram of an isolation testing system according to an embodiment of the present disclosure.
As shown in fig. 1, the isolation test system includes: a first antenna module 110, a second antenna module 120, a tester 130, an attenuator 140, a power divider 150, and a computer device 160.
A first antenna module 110.
A second antenna module 120.
The first antenna module 110 and the second antenna module 120 have a plurality of corresponding channels, and the first antenna module 110 and the second antenna module 120 are designed and laid out for the first antenna and the second antenna, respectively.
And a tester 130 for outputting a test signal.
It should be noted that the signal parameter settings of the tester 130, such as the transmission frequency band, the channel, the modulation mode, etc., need to be matched with the receiving parameter settings of the first antenna module 110 of the device under test, so as to output the test signal for testing.
The attenuator 140 is electrically connected to the second antenna module 120, and configured to attenuate the output signal of the second antenna module 120 according to the attenuation parameter.
Specifically, when the two frequency bands of the first antenna module and the second antenna module are relatively close to each other, and the output signal of the second antenna module 120 interferes with the receiving sensitivity of the first receiving module 110, the output signal of the second antenna module 120 is attenuated by the attenuation parameter of the attenuator 140, so that the interference of the transmission signal of the second antenna module on the second sensitivity of the first antenna module is continuously reduced, and when the value of the attenuator is attenuated to a certain degree, the second receiving sensitivity of the first antenna module is not affected completely, that is, the second receiving sensitivity is matched with the first receiving sensitivity.
Further, when the second receiving sensitivity is matched with the first receiving sensitivity, the attenuator meets the requirement of the isolation between the first antenna module and the second antenna module under the current condition, so that the attenuation value at the moment can be replaced by the target parameters of the first antenna module and the second antenna module.
The power divider 150 is electrically connected to the tester 130, the attenuator 140, and the first antenna module 110, and configured to combine the test signal of the tester 130 and the output signal attenuated by the attenuator 140 to obtain a combined signal.
The power divider 150 is also called a power divider, and is a device that divides one input signal energy into two or more paths to output equal or unequal energy, or conversely, combines multiple signal energy into one output, which may also be called a combiner.
In this embodiment, the power divider 150 is configured to combine the test signal of the tester 130 and the output signal of the second antenna module 120 attenuated by the attenuator 140 to obtain a combined signal, and functions as a combiner.
The computer device 160 is electrically connected to the first antenna module 110, the second antenna module 120, and the attenuator 140, respectively, and configured to test a first receiving sensitivity of the first antenna module 110 to the test signal; controlling the attenuator 140 to adjust to different attenuation parameters, and when the attenuator 140 is respectively tested to adjust to different attenuation parameters, the first antenna module 110 adjusts the second receiving sensitivity of the pair-path signal; when the second receiving sensitivity is matched with the first receiving sensitivity, the attenuation parameter of the attenuator 140 is taken as a target parameter; determining an isolation threshold according to the target parameters; the isolation threshold is used for performing an antenna isolation test on the first antenna and the second antenna when the first antenna module 110 is installed with the first antenna and the second antenna module 120 is installed with the second antenna.
Specifically, the computer device 160 is electrically connected to the first antenna module 110, the second antenna module 120, and the attenuator 140, respectively, and is configured to test a first receiving sensitivity of the first antenna module 110 to a test signal output by the tester 130. The receive sensitivity refers to a minimum threshold of the test signal that can be received by the first antenna module 110, that is, a minimum signal receive power at which the first antenna module 110 can correctly extract the useful signal.
The computer device 160 controls the attenuator 140 to adjust to different attenuation parameters, and tests the second receiving sensitivity of the first antenna module 110 to the combined signal when the attenuator 140 is adjusted to different attenuation parameters. When the second reception sensitivity is matched with the first reception sensitivity, the attenuation parameter of the attenuator 140 is taken as the target parameter.
The target parameter is an attenuation parameter of the attenuator 140 when the second receiving sensitivity matches the first receiving sensitivity.
To illustrate, the first receiving sensitivity is a limit index that the receiving sensitivity of each channel of the first antenna module 110 to the test signal, which is tested by the computer device 160, can reach when the second antenna module 120 is disconnected from the attenuator 140. As an example, when the attenuator 140 is set to 0, since the two frequency bands of the first antenna module 110 and the second antenna module 120 are relatively close, the transmission signal of the second antenna module 120 may cause interference to the receiving sensitivity of the first antenna module 110. At this time, the attenuator 140 may be adjusted to continuously reduce interference of the transmission signal of the second antenna module 120 on the second sensitivity of the first antenna module 110, and when the value of the attenuator 140 is attenuated to a certain degree, the second receiving sensitivity of the first antenna module 110 is not affected at all, that is, the second receiving sensitivity is matched with the first receiving sensitivity. When the second receiving sensitivity is matched with the first receiving sensitivity, the attenuator 140 satisfies the isolation between the first antenna module 110 and the second antenna module 120 under the current condition, and therefore the attenuation value at this time can be used as the target parameter of the first antenna module 110 and the second antenna module 120.
The isolation refers to a ratio of a signal sent by one antenna module and a signal received by the other antenna module to the transmitted signal. The higher the isolation, the more signals the antenna modules receive, and the less interference between the two antenna modules at that time. When the isolation of the two antenna modules is low, coexistence interference problems may occur.
For each channel, when the second receiving sensitivity of the current channel is matched with the first receiving sensitivity, the attenuation parameter of the attenuator 140 is used as the target parameter corresponding to the current channel. By changing the transmission signal of the second antenna module 120, the target parameters corresponding to the multiple channels of the first antenna module 110 are tested, the maximum value of the target parameters is determined according to the target parameters corresponding to the multiple channels, and the maximum value of the target parameters is used as the isolation threshold required after the antennas are installed on the first antenna module 110 and the second antenna module 120. The isolation between the first antenna module 110 and the second antenna module 120 can ensure that the transmission signal of the second antenna module 120 after the second antenna is installed does not affect the receiving sensitivity of the first antenna module 110 after the first antenna module is installed.
As a possible implementation manner, referring to fig. 2, on the basis of the embodiment shown in fig. 1, the isolation testing system further includes: a network tester 170.
The network tester 170 is electrically connected to the first antenna module 110 and the second antenna module 120, respectively, and configured to perform an antenna isolation test on the first antenna module 110 with the first antenna and the second antenna module 120 with the second antenna.
Further, according to the determined isolation threshold, a first antenna is installed on the first antenna module 110, and a second antenna is installed on the second antenna module 120, and the distance and the placement angle between the first antenna and the second antenna when the antennas are installed are determined. When the first antenna module 110 is installed with the first antenna and the second antenna module 120 is installed with the second antenna, the network tester 170 performs an antenna isolation test on the first antenna module installed with the first antenna and the second antenna module installed with the second antenna.
The network analyzer 170 is electrically connected to the computer device 160, and the computer device 160 obtains the antenna isolation between the first antenna and the second antenna tested by the network analyzer 170. If the obtained antenna isolation is lower than the isolation threshold, indicating that there is an interference problem between the first antenna and the second antenna, the computer device 160 sends a prompt message, where the prompt message is used to instruct to adjust the spatial relationship between the first antenna and the second antenna.
The spatial relationship here includes the distance between the antennas, the placement angle, and the like. For example, the distance between the first antenna and the second antenna may be adjusted so that the antenna isolation is increased, and thus there is no problem of interference between the first antenna and the second antenna.
It should be noted that, in the embodiment of the present application, the shape and the position of the component in the structure diagram are not limited, but are only used as an example to illustrate the isolation test system provided in the embodiment.
In the isolation test system of the embodiment of the invention, the first receiving sensitivity of the first antenna module 110 to the test signal is tested; when the attenuator 140 is adjusted to different attenuation parameters, the first antenna module 110 determines a second receiving sensitivity of the pair-path signal; the combined signal is obtained by combining the test signal of the tester 130 and the output signal attenuated by the attenuator 140; when the second receiving sensitivity is matched with the first receiving sensitivity, the attenuation parameter of the attenuator 140 is taken as a target parameter; finally, according to the target parameters, determining an isolation threshold; the isolation threshold is used for performing an antenna isolation test on the first antenna and the second antenna when the first antenna module 110 is installed with the first antenna and the second antenna module 120 is installed with the second antenna. According to the method, the isolation threshold values of the two antennas are obtained through pre-testing, so that the antennas can be conveniently and effectively designed and laid out, the problem of management of abnormal isolation caused by design and layout of the antennas according to manual experience in the prior art is solved, meanwhile, the isolation threshold values are prevented from being set depending on the manual experience in the isolation testing process, the accuracy is improved, and the labor cost is reduced.
To clearly illustrate the previous embodiment, this embodiment provides an isolation test method, which is applied to the isolation test system described in the foregoing embodiment, and specifically can be executed by computer equipment in the isolation test system, and fig. 3 is a schematic flow chart of the isolation test method provided in the embodiment of the present application.
As shown in fig. 3, the isolation test method may include the steps of:
Wherein the first antenna module and the second antenna module have a corresponding plurality of channels.
Specifically, the second antenna module is disconnected from the attenuator, and the computer device is used to test the first receiving sensitivity of each channel of the first antenna module to the test signal, where the test signal is output through the tester, and the signal parameter settings of the tester, such as the transmission frequency band, the channel, the modulation mode, etc., need to be matched with the receiving parameter settings of the first antenna module of the device under test to output the test signal for testing.
It should be noted that the receiving sensitivity refers to a minimum threshold of the test signal that can be received by the first antenna module, that is, a minimum signal receiving power at which the first antenna module can correctly extract the useful signal.
102, respectively testing the second receiving sensitivity of the combined signal of the first antenna module when the attenuators are adjusted to different attenuation parameters; the combined signal is obtained by combining the test signal of the tester and the output signal attenuated by the attenuator.
Specifically, the second antenna module is connected with the attenuator, the tester is controlled to transmit the test signal, the computer device respectively controls the attenuator to adjust to different attenuation parameters, and when the attenuator is respectively tested to adjust to different attenuation parameters, the second receiving sensitivity of each channel of the first antenna module to the combined signal is achieved.
The combined signal is obtained by combining the test signal output by the tester and the output signal attenuated by the attenuator through each radio frequency router.
And 103, when the second receiving sensitivity is matched with the first receiving sensitivity, taking the attenuation parameter of the attenuator as a target parameter.
The target parameter is an attenuation parameter of the attenuator when the second receiving sensitivity is matched with the first receiving sensitivity.
Specifically, the first antenna module and the second antenna module each have a plurality of corresponding channels, and when the second receiving sensitivity of the current channel is matched with the first receiving sensitivity for each channel, the attenuation parameter of the attenuator is used as the target parameter corresponding to the current channel.
To be further described, the first receiving sensitivity is a limit index that the receiving sensitivity of each channel of the first antenna module to the test signal can reach when the second antenna module is disconnected from the attenuator. As an example, when the attenuator is set to 0, since the two frequency bands of the first antenna module and the second antenna module are relatively close, the transmission signal of the second antenna module may cause interference to the receiving sensitivity of the first antenna module. At this time, the interference of the transmission signal of the second antenna module to the second sensitivity of the first antenna module can be continuously reduced by adjusting the attenuator, and when the value of the attenuator is attenuated to a certain degree, the second receiving sensitivity of the first antenna module is not affected completely, that is, the second receiving sensitivity is matched with the first receiving sensitivity. When the second receiving sensitivity is matched with the first receiving sensitivity, under the current condition of the attenuator, the isolation degree of the first antenna module and the second antenna module meets the requirement, so that the attenuation value at the moment can be replaced by the target parameters of the first antenna module and the second antenna module.
The isolation refers to a ratio of a signal sent by one antenna module and a signal received by the other antenna module to the transmitted signal. The higher the isolation, the more signals the antenna modules receive, and the less interference between the two antenna modules at that time. When the isolation of the two antenna modules is low, coexistence interference problems may occur.
104, determining an isolation threshold according to the target parameters; and the isolation threshold is used for carrying out antenna isolation test on the first antenna and the second antenna when the first antenna module is provided with the first antenna and the second antenna module is provided with the second antenna.
Specifically, for each channel, when the second receiving sensitivity of the current channel is matched with the first receiving sensitivity, the attenuation parameter of the attenuator is used as the target parameter corresponding to the current channel. The method comprises the steps of testing target parameters corresponding to a plurality of channels of a first antenna module by changing a transmitting signal of a second antenna module, determining the maximum value of the target parameters according to the target parameters corresponding to the plurality of channels, and taking the maximum value of the target parameters as an isolation threshold required after antennas are installed on the first antenna module and the second antenna module. The isolation between the first antenna module and the second antenna module can ensure that the transmitting signal of the second antenna module after the second antenna is installed on the first antenna module has no influence on the receiving sensitivity of the first antenna module after the first antenna module is installed on the second antenna module.
Further, according to the determined isolation threshold, a first antenna is installed on the first antenna module, a second antenna is installed on the second antenna module, and the distance and the placing position angle of the first antenna and the second antenna are determined during installation. When the first antenna module is provided with the first antenna and the second antenna module is provided with the second antenna, the network tester is used for carrying out antenna isolation test on the first antenna module provided with the first antenna and the second antenna module provided with the second antenna.
The computer device obtains an antenna isolation between the first antenna and the second antenna tested by the network analyzer. And if the obtained antenna isolation is lower than the isolation threshold, indicating that the interference problem exists between the first antenna and the second antenna, sending prompt information by the computer equipment, wherein the prompt information is used for indicating to adjust the spatial relationship between the first antenna and the second antenna.
The spatial relationship here includes the distance between the antennas, the placement angle, and the like. For example, the distance between the first antenna and the second antenna may be adjusted so that the antenna isolation is increased, and thus there is no problem of interference between the first antenna and the second antenna.
According to the isolation testing method, when the first receiving sensitivity of the first antenna module to the testing signal is tested and the attenuator is adjusted to different attenuation parameters, the second receiving sensitivity of the first antenna module to the combined signal is matched with the first receiving sensitivity, the attenuation parameters of the attenuator are used as target parameters, finally, the isolation threshold value is determined according to the target parameters, and then the first antenna and the second antenna are subjected to antenna isolation testing through the isolation threshold value. According to the method, the isolation threshold values of the two antennas are obtained through pre-testing, so that the antennas can be conveniently and effectively designed and laid out, the problem of management of abnormal isolation caused by design and layout of the antennas according to manual experience in the prior art is solved, meanwhile, the isolation threshold values are prevented from being set depending on the manual experience in the isolation testing process, the accuracy is improved, and the labor cost is reduced.
