The terminal 102 may obtain a test signal sent by the device to be tested 104 to the radio frequency parameter testing device 106, and obtain an error vector magnitude and a transmission power corresponding to a radio frequency antenna connected to the device to be tested 104 according to the test signal, and the terminal 102 may further determine a test result of the radio frequency antenna according to the obtained error vector magnitude, the obtained transmission power, and a reception sensitivity index obtained based on a packet loss test of the device to be tested 104 and the radio frequency parameter testing device 106, and according to a magnitude of the reception sensitivity. The terminal 102 may be, but is not limited to, various personal computers, notebook computers, smart phones, and tablet computers.
In an embodiment, as shown in fig. 2, a method for testing a radio frequency antenna is provided, which is described by taking the method as an example for being applied to the terminal in fig. 1, and includes the following steps:
step S202, obtaining a test signal sent by the device to be tested 104 to the radio frequency parameter testing device 106, and obtaining an error vector magnitude and a transmitting power corresponding to a radio frequency antenna connected with the device to be tested 104 according to the test signal.
The device under test 104 may be a device where the rf antenna is located, and the device under test 104 may be a device for communication, for example, may communicate with other devices through the rf antenna; the rf parameter testing device 106 may be a device for testing the relevant index of the rf antenna, for example, may receive the relevant data from the rf antenna and send the data to the terminal 102 for analysis. The rf parameter testing device 106 may be provided with an integrated tester antenna, and the rf parameter testing device 106 may receive related data and signals sent by the rf antenna through the integrated tester antenna. The rf antenna, the integrated tester antenna, and the device under test 104 may be disposed in the same shielding box, and the rf antenna and the integrated tester antenna may have the same horizontal height.
In an embodiment, the rf antenna may be an antenna in a 230MHz frequency band, which may be referred to as a 230MHz antenna, the device under test 104 may first establish a communication connection with the rf parameter testing device 106, and the communication connection may be confirmed by the terminal 102, for example, when the terminal 102 detects a communication signal between the 230MHz antenna and the integrated tester, it may be confirmed that the communication connection between the device under test 104 and the rf parameter testing device 106 is already achieved.
After the terminal 102 confirms that the device to be tested 104 establishes a communication connection with the rf parameter testing device 106, a radio frequency index corresponding to the device to be tested 104 may be obtained, for example, by obtaining a testing signal sent by the device to be tested 104 to the rf parameter testing device 106, and obtaining the radio frequency index from the testing signal, for example, the testing signal may be coupled with an integrated tester antenna through a radio frequency antenna of the device to be tested 104 and transmitted to the rf parameter testing device 106, and the terminal 102 obtains the received testing signal from the rf parameter testing device 106. The rf indicator may include an error vector magnitude and a transmission power of the rf antenna, that is, the terminal 102 may obtain the error vector magnitude and the transmission power corresponding to the rf antenna from the test signal. The terminal 102 may determine whether the obtained error vector magnitude and the obtained transmission power meet the preset requirement after performing corresponding determination on the obtained error vector magnitude and the obtained transmission power.

The terminal 102 may obtain the receiving sensitivity corresponding to the rf antenna based on the obtained error vector magnitude, the transmitting power, and the receiving sensitivity index. For example, the terminal 102 may determine, by determining whether the value of the error vector magnitude meets the requirement, and based on a result of the determination, processing that the terminal 102 needs to perform, for example, after the determination is passed, the terminal 102 may perform corresponding calculation by using the transmission power and the reception sensitivity index, so as to obtain the reception sensitivity corresponding to the radio frequency antenna.
And step S206, determining the test result of the radio frequency antenna according to the receiving sensitivity.

The terminal 102 may determine a test result of the relevant index of the rf antenna according to the magnitude of the receiving sensitivity. For example, if the receiving sensitivity is greater than the preset sensitivity threshold, the terminal 102 may determine that the test result of the rf antenna is a pass. In addition, the test result of the radio frequency antenna may further include the error vector magnitude and the transmission power, in some embodiments, the terminal 102 may further determine that the test result of the radio frequency antenna passes after determining that the error vector magnitude, the transmission power, and the reception sensitivity all meet the requirements, and the reception sensitivity may be calculated on the premise that the error vector magnitude and the transmission power both meet the requirements; if any one of the error vector magnitude, the transmission power and the receiving sensitivity is not satisfactory, the test is not passed, and the terminal 102 may perform corresponding processing, including retesting or recalculation, according to the type of the parameter that is not passed.
In the radio frequency antenna test method, a test signal sent by a device to be tested to a radio frequency parameter test device is obtained, and an error vector amplitude and a transmitting power corresponding to a radio frequency antenna connected with the device to be tested are obtained according to the test signal; and then, according to the error vector magnitude, the transmitting power and the receiving sensitivity index obtained based on the packet loss test, obtaining the receiving sensitivity corresponding to the radio frequency antenna, so that the test result of the radio frequency antenna can be determined according to the size of the receiving sensitivity. Compared with the traditional mode of simply verifying the radio-frequency antenna through the frequency spectrograph equipment, the scheme has the advantages that the equipment to be tested and the radio-frequency parameter testing equipment are arranged, the testing signal between the equipment to be tested and the radio-frequency parameter testing equipment is obtained, and parameters such as the error vector amplitude, the transmitting power and the receiving sensitivity corresponding to the radio-frequency antenna are calculated and obtained based on the testing signal, so that the testing of the related indexes of the radio-frequency antenna is realized, and the completeness of the radio-frequency antenna index testing is improved.
In one embodiment, acquiring a test signal sent by the device under test 104 to the rf parameter testing device 106, and acquiring an error vector magnitude and a transmission power corresponding to an rf antenna connected to the device under test 104 according to the test signal includes: controlling the device to be tested 104 to send a test signal to the radio frequency parameter testing device 106 through the radio frequency antenna; obtaining error vector amplitudes of a plurality of channels corresponding to the radio frequency antenna and to-be-confirmed transmitting powers of the plurality of channels according to the test signals; judging whether the power difference value between the to-be-confirmed transmitting powers of the plurality of channels is within a preset power difference value range or not; if yes, obtaining the transmitting power corresponding to the radio frequency antenna according to the transmitting power to be confirmed of the plurality of channels.
In this embodiment, the test signal may be a signal sent by the device under test 104 to the rf parameter testing device 106 through the rf antenna, and the rf parameter testing device 106 may receive the test signal through the integrated tester antenna thereon. The terminal 102 may obtain the error vector magnitude and the transmission power corresponding to the rf antenna from the test signal. The terminal 102 may first control the device under test 104 to send a test signal to the rf parameter testing device 106 through the rf antenna, for example, the terminal 102 may send a signal sending instruction to the device under test 104, the device under test 104 may send the test signal to the rf parameter testing device 106 after receiving the signal, and the rf parameter testing device 106 may receive the test signal through the integrated tester antenna. The terminal 102 may obtain the error vector magnitudes of the multiple channels corresponding to the rf antenna and the to-be-confirmed transmission powers of the multiple channels according to the test signal received by the rf parameter testing device 106. Therefore, the terminal 102 may obtain the error vector magnitudes corresponding to the radio frequency antenna based on the error vector magnitudes of the multiple channels, and since the test result may include the error vector magnitudes, the terminal 102 may detect the error vector magnitudes of the multiple channels, and if the detection passes, it may be determined that the error vector magnitudes meet the requirements. The transmission power to be confirmed can be information which needs to be detected and judged to determine whether the transmission power meets the requirement. The terminal 102 may determine the to-be-confirmed transmission powers of the multiple channels, and determine whether a power difference between the to-be-confirmed transmission powers of the multiple channels is within a preset power difference range, if so, the terminal 102 may confirm that the to-be-confirmed transmission powers meet requirements, so that the transmission power corresponding to the radio frequency antenna may be obtained according to the to-be-confirmed transmission powers of the multiple channels. For example, the average or the sum of the transmission powers of the multiple channels may be used as the transmission power corresponding to the rf antenna.
In addition, in some embodiments, if the power difference between the to-be-confirmed transmission powers of the multiple channels is outside the preset power difference range, the terminal 102 may determine that the to-be-confirmed transmission power does not meet the requirement, that is, through the test, the terminal 102 may send a prompt to debug the position or angle of the device to be tested 104, and return to the step of controlling the device to be tested 104 to send the test signal to the radio frequency parameter testing device 106, so that the test of the radio frequency antenna index may be performed again.
By the embodiment, the terminal 102 may obtain the error vector magnitude and the transmission power based on the test signal, and may perform threshold judgment on the transmission power to determine that the transmission power meets the requirement, thereby improving the integrity of the radio frequency antenna index test.
In one embodiment, obtaining the receiving sensitivity corresponding to the radio frequency antenna according to the error vector magnitude, the transmitting power, and a receiving sensitivity index obtained based on a packet loss test includes: judging whether a vector magnitude difference value between the error vector magnitudes of the channels and the error vector magnitude of the corresponding channel in the device to be tested is within a preset vector magnitude difference value range or not; if so, acquiring the spatial path attenuation between the device to be tested 104 and the radio frequency parameter testing device 106 according to the transmitting power; and acquiring the receiving sensitivity corresponding to the radio frequency antenna according to the spatial path attenuation and the receiving sensitivity index obtained based on the packet loss test.
In this embodiment, the terminal 102 may obtain the receiving sensitivity corresponding to the radio frequency antenna according to the error vector magnitude, the transmitting power, and the receiving sensitivity index obtained from the test signal, for example, the terminal 102 may perform detection and judgment on the error vector magnitude, and obtain the receiving sensitivity corresponding to the radio frequency antenna according to the transmitting power and the receiving sensitivity index after the error vector magnitude passes the detection and judgment, the flow chart of the steps in this embodiment may be as shown in fig. 3, and fig. 3 is a flow chart of the receiving sensitivity obtaining step in one embodiment. The terminal 102 may determine whether a vector magnitude difference between the error vector magnitudes of the plurality of channels obtained from the test signal and the error vector magnitude of the channel corresponding to the device under test 104 is within a preset vector magnitude difference range, if so, the terminal 102 may determine that the error vector magnitudes of the plurality of channels obtained from the test signal meet requirements, and if the terminal 102 determines that the error vector magnitudes meet requirements, the terminal 102 may obtain the spatial path attenuation between the device under test 104 and the radio frequency parameter testing device 106 according to the transmission power. Where the spatial path attenuation may be a loss value, the terminal 102 may obtain the spatial path attenuation by performing a correlation calculation on the transmission power and combining the line loss. The terminal 102 may obtain the reception sensitivity corresponding to the radio frequency antenna by calculating the obtained spatial path attenuation and the reception sensitivity index obtained based on the packet loss test between the device to be tested 104 and the radio frequency parameter testing device 106.
In addition, in some embodiments, if the vector magnitude difference between the error vector magnitudes of the multiple channels obtained from the test signal and the error vector magnitude of the corresponding channel in the device under test 104 is not within the preset vector magnitude difference range, the terminal 102 may determine that the error vector magnitude does not pass the test, at this time, the terminal 102 may send a prompt to debug the stability of the radio frequency antenna of the device under test 104, and may return to the step of controlling the device under test 104 to send the test signal to the radio frequency parameter testing device 106, that is, perform the test of the radio frequency antenna index again.

The terminal 102 may obtain a line loss of the radio frequency coaxial line corresponding to the radio frequency antenna, where the line loss of the radio frequency coaxial line may also be referred to as a line loss of a radio frequency H axis, and the line loss may be a line loss fixed by each radio frequency antenna. The terminal 102 may further obtain the wireless receiving power corresponding to the radio frequency parameter testing device 106 according to the transmitting power, for example, after the device to be tested 104 sends the test signal to the radio frequency parameter testing device 106 by using the transmitting power, the terminal 102 may obtain the wireless receiving power corresponding to the test signal received by the radio frequency parameter testing device 106 from the radio frequency parameter testing device 106, where the wireless receiving power may be a power obtained after the transmitting power is lost. The terminal 102 may obtain the spatial path attenuation according to the line loss of the radio frequency coaxial line, the transmission power of the device to be tested 104, and the wireless receiving power corresponding to the radio frequency parameter testing device 106, for example, the terminal 102 may obtain a sum of the transmission power and the line loss of the radio frequency coaxial line, and a difference between the sum of the transmission power and the line loss of the radio frequency coaxial line and the wireless receiving power, to obtain the spatial path attenuation, specifically, a calculation formula of the spatial path attenuation may be as follows: the spatial path attenuation is the transmission power of the device under test 104 + the line loss of the rf coaxial line-the wireless reception power of the rf parametric test device 106.

In this embodiment, the terminal 102 may further perform packet loss test on the device to be tested 104 and the radio frequency parameter testing device 106 to obtain the receiving sensitivity index. The terminal 102 may control the radio frequency parameter device 106 to send test data to the device to be tested 104, where the test data may be a data packet used for performing a packet loss test on the device to be tested 106, and the terminal 102 may compare the received data received by the device to be tested 104 with the sent test data, thereby calculating a reception sensitivity index of the device to be tested 104. In addition, the device under test 104 may not receive the test data, and if the terminal 102 detects that the device under test 104 does not receive the test data, the terminal 102 may send a prompt that the link received by the device under test 104 is abnormal.
After obtaining the receive sensitivity index, the terminal 102 may obtain the receive sensitivity corresponding to the rf antenna by using the spatial path attenuation and the receive sensitivity index, for example, the terminal 102 may obtain the sum of the receive sensitivity index and the spatial path attenuation to obtain the receive sensitivity corresponding to the rf antenna. The calculation formula of the receiving sensitivity can be as follows: the reception sensitivity is the reception sensitivity index + spatial path attenuation. The terminal 102 may send a test passing prompt when it is determined that the receiving sensitivity meets the requirement, for example, when the receiving sensitivity is greater than a preset sensitivity threshold, and determine that the test on the index of the radio frequency antenna is completed.
Through the embodiment, the terminal 102 may obtain the receiving sensitivity index corresponding to the device to be tested 104 based on the packet loss test, and may obtain the receiving sensitivity corresponding to the radio frequency antenna based on the receiving sensitivity index and the spatial path attenuation, thereby improving the integrity of the radio frequency antenna index test.
In one embodiment, a method for testing a radio frequency antenna is provided, where the method can test the radio frequency antenna in a 230MHz frequency band, and includes the following steps:
when the device to be tested 104 is in communication connection with the rf parameter device 106 through the rf antenna, the terminal 102 obtains the rf indexes of the device to be tested, including the error vector magnitude, the transmission power, and the receiving sensitivity, and when the error vector magnitude, the transmission power, and the receiving sensitivity all meet the requirements, the terminal 102 confirms that the various indexes of the rf antenna pass the test. Wherein the radio frequency antenna may be a radio frequency antenna in the 20MHz frequency band.
The terminal 102 may control the to-be-tested device 104 to transmit a signal, control the radio frequency parameter testing device 106 to receive the signal, and test an error vector magnitude and a transmission power of each channel of the radio frequency antenna according to the signal received by the radio frequency parameter testing device 106, and the terminal 102 may determine whether a power difference value between the transmission powers of each channel is within a preset power difference value range; when the power difference value is not within the preset power difference value range, the terminal 102 may send a prompt to debug the position or angle of the device to be tested 104, and return to the step of controlling the device to be tested 104 to transmit a signal; the terminal 102 may further determine whether a vector magnitude difference between the error vector magnitude of each channel and the error vector magnitude of the corresponding channel of the device under test 104 is within a preset vector magnitude difference range; when the vector magnitude difference value is not within the preset vector magnitude difference value range, the terminal 102 can send a prompt for debugging the antenna stability of the prototype and return to the step of controlling the to-be-tested device 104 to transmit signals; when the power difference value is within the preset power difference value range and the vector magnitude difference value is within the preset vector magnitude difference value range, the terminal 102 may determine that the error vector magnitude and the transmission power of the device to be tested 104 meet the requirements.
The terminal 102 may calculate the above-mentioned reception sensitivity with the transmission power satisfying the requirement. For example, the terminal 102 may calculate a spatial path attenuation between the device under test 104 and the rf parameter testing device 106 by using the corresponding transmission power of the device under test 104, and calculate the receiving sensitivity of the device under test 104 based on the spatial path attenuation. The terminal 102 may obtain the corresponding wireless receiving power from the rf parameter testing device 106 according to the transmitting power, and the terminal 102 may obtain the spatial path attenuation based on the following formula: the spatial path attenuation is the transmission power of the device under test 104 + the line loss of the rf coaxial line-the wireless reception power of the rf parametric test device 106.
The terminal 102 may further obtain a reception sensitivity index corresponding to the device to be tested 104 based on the packet loss test, for example, the terminal 102 may control the radio frequency parameter testing device 106 to transmit a data packet for performing the packet loss test on the device to be tested 104; judging whether the radio frequency parameter testing equipment 106 receives a data packet sent by the equipment to be tested 104; when the terminal 102 detects that the rf parameter testing device 106 does not receive the data packet sent by the device to be tested 104, the terminal 102 may send a prompt that the receiving link of the device to be tested 104 is abnormal. When detecting that the data packet sent by the device to be tested 104 is received, the terminal 102 may calculate the receiving sensitivity index of the device to be tested 104 according to the data packet sent by the radio frequency parameter testing device 106 and the data packet sent by the device to be tested 104.
The terminal 102 may obtain the receiving sensitivity corresponding to the rf antenna based on the receiving sensitivity index and the spatial path attenuation. For example, the terminal 102 may obtain the reception sensitivity by the following formula: the reception sensitivity is the reception sensitivity index + spatial path attenuation. When the terminal 102 determines that the receiving sensitivity meets the preset requirement, for example, is greater than the preset sensitivity threshold, it may determine that the test of the rf antenna passes.
Through the embodiment, the terminal 102 obtains the test signal between the two devices, and calculates and obtains parameters such as an error vector amplitude, a transmitting power, a receiving sensitivity and the like corresponding to the radio frequency antenna based on the test signal, so that the test of the related indexes of the radio frequency antenna is realized, and the integrity of the test of the indexes of the radio frequency antenna is improved.
