All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present application without making any creative effort, shall fall within the protection scope of the present application.
The traditional 2.4G signal has narrow bandwidth, and more electronic devices use 2.4G signals, so that the wireless network environment is crowded, and the interference between the devices is large. The 5G network is rapidly started by virtue of the advantages of wide frequency, clean wireless network environment, small interference between devices, stable network speed, capability of supporting higher wireless network speed and the like, and the layout of the Internet of things is accelerated. Currently, more and more products are capable of supporting the transmission of both 2.4G and 5G radio frequency signals. In order to ensure the usability of such products, a radio frequency test method is needed to test the radio frequency signals of the products in the production stage of the products, so as to prevent the products with defects in Wifi radio frequency capability from entering the market.
In order to explain the technical means of the present application, the following description will be given by way of specific examples.
Fig. 1 shows a schematic implementation flow diagram of a radio frequency testing method provided in an embodiment of the present application, where the method can be applied to a test terminal and is applicable to a case where a Wifi radio frequency capability of a product needs to be tested. The test terminal can be a computer, a smart phone and other terminals.
Specifically, the radio frequency testing method may include the following steps S101 to S103.
And step S101, sending a test instruction to the terminal to be tested.
The terminal to be tested refers to a terminal which needs to perform a Wifi radio frequency capability test, and can be a mobile phone, an earphone and other terminals capable of supporting 2.4G and 5G radio frequency signals.
In an embodiment of the application, the test instruction is used to instruct the terminal to be tested to send the radio frequency signal according to the test frequency point. And after the terminal to be tested receives the test instruction sent by the test terminal, the terminal to be tested can start to send radio frequency signals according to the test frequency point.
It should be noted that the test frequency points may be adjusted according to actual conditions, and the test frequency points may include frequency points corresponding to 2.4G radio frequency signals, and may also include frequency points corresponding to 5G video signals.
In some embodiments of the present application, the test frequency point may be at least one of 2437MHz, 5180MHz, 5320MHz, 5560MHz, 5640MHz, and 5825 MHz. Experiments show that the Wifi radio frequency function of the terminal to be tested can be tested completely by testing and analyzing radio frequency signals of the terminal to be tested under six frequencies of 2437MHz, 5180MHz, 5320MHz, 5560MHz, 5640MHz and 5825 MHz.
Step S102, a target power spectrogram generated according to the radio-frequency signal is obtained, and the maximum output power of the radio-frequency signal is obtained.
Wherein, the target power spectrogram records a corresponding relationship between the frequency and the output power. By acquiring the target power spectrogram generated according to the radio frequency signal, the output power corresponding to each frequency point of the radio frequency signal can be obtained from the target power spectrogram, and the maximum output power of the radio frequency signal, namely the maximum value of the output power corresponding to each frequency point, can be obtained from the output power spectrogram.
In some embodiments of the present application, the test terminal may obtain the target power spectrogram through a spectrometer. The frequency spectrograph is an instrument for analyzing a signal frequency domain, and can generate a target power spectrogram according to a radio-frequency signal sent by a terminal to be tested.
In order to ensure the reliability of the test result, as shown in fig. 2, the terminal 21 to be tested may be disposed in a shielding box 22, where the shielding box 22 is used to prevent interference of external radio frequency signals, and facilitate the spectrum analyzer 23 to detect the radio frequency signals sent by the terminal 21 to be tested. After the radio frequency test is started, the test terminal 24 may send a test instruction to the terminal to be tested 21, and the terminal to be tested 21 sends a radio frequency signal in the shielding box 22. The spectrometer 23 may generate a target power spectrogram according to a radio frequency signal transmitted by the terminal 21 to be tested in the shielding box 22. Then, the test terminal 24 acquires a target power spectrogram generated by the spectrometer 23, and analyzes the target power spectrogram to obtain the maximum output power of the radio frequency signal.
In order to reduce the burden of the test terminal, in some embodiments of the present application, as shown in fig. 3, the acquiring the target power spectrogram generated according to the radio frequency signal may include the following steps S301 to S302.
Step S301, detecting whether a signal with an output power value larger than a second power threshold exists in a power spectrogram generated by a frequency spectrograph in real time according to a radio frequency signal sent by a terminal to be detected.
The power spectrogram is generated by a frequency spectrograph in real time according to a radio frequency signal sent by a terminal to be tested in real time.
Step S302, if there is a signal whose output power value is greater than the second power threshold in the power spectrogram generated by the frequency spectrograph in real time according to the radio frequency signal sent by the terminal to be tested, starting to collect the power spectrogram generated by the frequency spectrograph in real time according to the radio frequency signal sent by the terminal to be tested, so as to obtain the target power spectrogram.
The second power threshold represents the power corresponding to the effective signal, and can be adjusted according to the actual situation. If no signal with the output power value larger than the second power threshold value exists in the power spectrogram, the power spectrogram does not contain an effective signal; if a signal with an output power value greater than the second power threshold exists in the power spectrogram, the signal represents an effective signal in the power spectrogram, and at this time, the power spectrogram generated by the frequency spectrograph according to the radio-frequency signal sent by the terminal to be tested can be collected to obtain a target power spectrogram, so as to screen out the power spectrogram not containing the effective signal.
Fig. 4 shows a target power spectrum diagram in which the effective signal is a bandpass signal with a flat top.
Step S103, comparing the maximum output power of the radio frequency signal with a first power threshold value to obtain a radio frequency test result of the terminal to be tested at the test frequency point.
The first probability threshold value represents the minimum value of the maximum output power corresponding to the radio frequency signal transmitted by the terminal to be tested with good radio frequency function at the test frequency point Wifi, and the specific value can be adjusted according to the actual situation. When the maximum output power of the radio frequency signal is greater than or equal to the first power threshold, which indicates that the Wifi radio frequency sending capability of the terminal to be tested at the test frequency point is normal, the radio frequency test result can be confirmed as that the radio frequency function of the terminal to be tested at the test frequency point is good. When the maximum output power of the radio frequency signal is smaller than the first power threshold, which indicates that the radio frequency sending capability of the terminal to be tested at the test frequency point is abnormal, the radio frequency test result can be confirmed as that the radio frequency function of the terminal to be tested at the test frequency point is abnormal.
It should be noted that, if the test frequency points include a plurality of test frequency points, when the maximum value of the output power of the terminal to be tested at each test frequency point is greater than or equal to the first power threshold, the radio frequency test result may be determined that the radio frequency function of the terminal to be tested is good.
In the embodiment of the application, the maximum output power of the radio-frequency signal is obtained by sending a test instruction to the terminal to be tested and acquiring a target power spectrogram generated according to the radio-frequency signal; then, the maximum output power of the radio frequency signal is compared with the first power threshold value to obtain a radio frequency test result of the terminal to be tested at the test frequency point, the radio frequency capability of the terminal to be tested at different test frequency points can be tested by using the target power spectrogram, complex calculation or switching operation is not needed, and the test efficiency is improved.
To ensure the reliability of the test results, in some embodiments of the present application, the test analysis may be performed by collecting the spectrometer signals multiple times.
Specifically, in some embodiments of the present application, the obtaining a target power spectrogram by the collection-starting spectrometer according to a power spectrogram generated in real time by a radio frequency signal sent by a terminal to be tested may include: and acquiring a power spectrogram generated by a preset frequency acquisition spectrometer in real time according to a radio frequency signal sent by the terminal to be tested to obtain a plurality of target power spectrograms.
After receiving the test instruction, the terminal to be tested can continuously send the radio-frequency signal within a period of time, and the frequency spectrograph can generate a power frequency spectrogram in real time according to the radio-frequency signal sent by the terminal to be tested. With the change of time, the radio frequency signal sent by the terminal to be tested may change, and the power spectrogram generated by the spectrometer may also change accordingly. The test terminal collects the power spectrograms at the preset frequency, a plurality of target power spectrograms can be obtained, and the reliability of the experimental result can be ensured by analyzing the target power spectrograms.
It should be noted that the preset frequency may be adjusted according to actual situations. Moreover, in some embodiments of the present application, the power spectrograms may be collected at a preset frequency until the number of the obtained target power spectrograms is equal to a preset number threshold.
Wherein, the number threshold value can be adjusted according to the actual situation. For example, the number threshold may be 15, that is, 15 target power spectrograms are collected at a preset frequency, and the radio frequency test result of the terminal to be tested at the test frequency point is obtained by analyzing the 15 target power spectrograms.
Specifically, as shown in fig. 5, the comparing the maximum value of the output power of the radio frequency signal with the first power threshold to obtain the radio frequency test result of the terminal to be tested at the test frequency point may include: step S501 to step S502.
Step S501, a power average of maximum output powers of the radio frequency signals respectively corresponding to the plurality of target power spectrograms is calculated.
Step S502, comparing the power average value with a first power threshold value to obtain a radio frequency test result of the terminal to be tested at the test frequency point.
The method includes the steps of continuing to explain by acquiring 15 target power frequency spectrograms, wherein each target power frequency spectrogram corresponds to a maximum value of output power, and obtaining a radio frequency test result of the terminal to be tested at the test frequency point by solving a power average value of the 15 maximum output powers and comparing the power average value with a first power threshold value. If the average power value is greater than or equal to the first power threshold value, which indicates that the Wifi radio frequency sending capability of the terminal to be tested at the test frequency point is normal, the radio frequency test result can confirm that the radio frequency function of the terminal to be tested at the test frequency point is good. If the average power value is smaller than the first power threshold, it indicates that the Wifi radio frequency sending capability of the terminal to be tested at the test frequency point is abnormal, and the radio frequency test result can confirm that the radio frequency function of the terminal to be tested at the test frequency point is abnormal.
In the embodiment of the application, the power average value of the maximum output power of the radio frequency signals respectively corresponding to the target power frequency spectrograms is calculated, and the power average value is compared with the first power threshold value to obtain the radio frequency test result of the terminal to be tested at the test frequency point, so that the accidental radio frequency test can be avoided, and the reliability of the radio frequency test result is improved.
Furthermore, the test instruction can be used for instructing the terminal to be tested to send the radio frequency signal at a preset time point according to the test frequency point, so that the test terminal can conveniently acquire the target power spectrogram.
On this basis, the preset time point comprises a plurality of target time points. Accordingly, the step S102 may include: and respectively collecting target power spectrograms at a plurality of target time points. The step S103 may include: and comparing the maximum output power corresponding to each target time point in the target time points with a first power threshold value respectively to obtain a radio frequency test result of the terminal to be tested at the test frequency point.
The number of the target time points may be adjusted according to actual conditions, and may be, for example, 5.
That is to say, a plurality of target power spectrograms can be obtained by respectively collecting the target power spectrograms at a plurality of target time points, and the radio frequency test result of the terminal to be tested at the test frequency point can be obtained by comparing the maximum output power in each collected target power spectrogram with the first power threshold value. If the maximum output power in each collected target power spectrogram is greater than or equal to the first power threshold, which indicates that the Wifi radio frequency sending capability of the terminal to be tested at the test frequency point is normal, the radio frequency test result can confirm that the radio frequency function of the terminal to be tested at the test frequency point is good.
In the embodiment of the application, the target power frequency spectrograms are respectively collected at the target time points, the maximum output power corresponding to each target time point in the target time points is respectively compared with the first power threshold value, the terminal to be tested is obtained, the radio frequency test result of the test frequency point can be obtained, the accidental occurrence of a single time point can be avoided, and the reliability of the radio frequency test result is improved.
It should be noted that, in some embodiments of the present application, the above-mentioned power collection at multiple target time points may be used in combination with the method shown in fig. 5.
Specifically, according to the received test instruction, the terminal to be tested respectively starts to send radio frequency signals according to the test frequency points at a plurality of preset time points, and continuously sends the radio frequency signals for a period of time. Starting at each target time point, the test terminal may collect the power spectrograms at a preset frequency until the number of the obtained target power spectrograms is equal to a preset number threshold, then calculate a power average value of maximum output powers respectively corresponding to the plurality of spectrometer signals corresponding to the target time point, and compare the power average value with the first power threshold. And if the average power value corresponding to each target time point is greater than or equal to the first power threshold, the radio frequency test result of the terminal to be tested at the test frequency point is that the radio frequency function of the terminal to be tested at the test frequency point is good.
For example, the test terminal collects target power spectrograms of 5 different target time points, and starts to collect the power spectrograms for 15 times at each target time point by using a preset frequency, and if the power average values of the maximum output powers respectively corresponding to the 15 power spectrograms corresponding to the 5 different target time points are all greater than or equal to a first power threshold value, the radio frequency test result of the terminal to be tested at the test frequency point is that the radio frequency function of the terminal to be tested at the test frequency point is good.
It should be noted that the radio Frequency test method provided by the present application may be applied to a terminal to be tested that uses an Orthogonal Frequency Division Multiplexing (OFDM) module. Generally, the test of non-OFDM signals only needs to test the performance of a single channel, and the production test cannot be realized for OFDM signals. The radio frequency test method breaks through the single test concept of the traditional non-OFDM signal, and widens the boundary of WIFI signal test. Fig. 5 is a target power spectrogram obtained when testing a terminal to be tested such as an OFDM module, where the target power spectrogram includes a band-pass signal with a flat top. When the terminal to be tested is an OFDM module terminal, the maximum value of the output power can appear at any frequency point in the frequency band corresponding to the flat top.
Further, in some embodiments of the present application, when the terminal to be tested is an OFDM module terminal, the radio frequency testing method may further include: and comparing the frequency point corresponding to the maximum output power of the radio frequency signal with the test frequency point to obtain a radio frequency test result of the terminal to be tested at the test frequency point.
Specifically, if the frequency difference between the frequency point corresponding to the maximum value of the output power of the radio frequency signal and the test frequency point is smaller than the preset frequency difference threshold, the radio frequency test result may be determined as that the radio frequency function of the terminal to be tested at the test frequency point is good. That is to say, the closer the frequency point corresponding to the maximum value of the output power of the radio frequency signal is to the test frequency point, the better the Wifi radio frequency function of the OFDM module terminal is.
It should be noted that, for simplicity of description, the foregoing method embodiments are described as a series of acts or combination of acts, but those skilled in the art will recognize that the present application is not limited by the order of acts, as some steps may, in accordance with the present application, occur in other orders.
