[0028] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the embodiment described below is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] In the description of the present utility model, it is to be understood that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component at the same time. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a centrally arranged component at the same time.

[0030] In addition, terms such as "long", "short", "inside" and "outside" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings and are only used to facilitate the description of the present invention. They do not indicate or imply that the device or component referred to must have this specific direction or operate with a specific direction structure, and should not be understood as a limitation of the present invention.

[0031] With the development of communication services, there are more and more mobile phone frequency bands, and radiation spurious is a regulatory issue. If the radiation spurious does not meet the standard, the mobile phone will not be able to be put on the market. The importance is self-evident. Based on this, there are many frequency bands that need to be covered during testing, and each test frequency band takes a long time, resulting in a large test cost. The utility model aims to solve the problems of low efficiency and high cost of radiation spurious testing. By providing a simple radiation spurious testing device to perform a preliminary scan on the test target, after the high-risk test target is found, it is transferred to a third-party laboratory for retesting, which greatly improves the efficiency of radiation spurious debugging and effectively reduces the test cost. On this basis, if a simple device is used to pre-scan once and 5-10 frequency bands are found to be retested in the laboratory, the test time and test cost can be effectively reduced, which greatly improves the test efficiency and saves costs. At the same time, since the test time of the simple device is extremely short, most of the frequency bands can be pre-scanned to effectively reduce the risk of RSE not meeting the standard.

[0032] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0033] Please refer to Figure 1 , an embodiment of the utility model is a radiation stray test device, comprising an energy detection head 11, the energy detection head 11 is used to approach a test target during testing to receive harmonic energy radiated by the test target;

[0034] In this embodiment, the energy detection head 11 includes a ring-shaped receiving antenna 111 , through which the harmonic energy radiated by the target can be more effectively received, thereby improving the accuracy and reliability of the test.

[0035] The radiated stray test equipment also includes:

[0036] The energy processing unit 12 is electrically connected to the energy detection head 11, and is used to receive the harmonic energy from the energy detection head 11 and convert the harmonic energy into an electrical signal; by converting the harmonic energy into an electrical signal, the signal can be more conveniently processed and analyzed, thereby achieving accurate measurement of the radiation energy of the test target.

[0037] The result output unit 13 is electrically connected to the energy processing unit 12. The result output unit 13 is used to obtain the energy interval of the harmonic energy according to the level value of the electrical signal, and output the test result to intuitively understand the harmonic energy radiated by the test target, which is conducive to quickly selecting the test target that needs to be further tested in the darkroom.

[0038] Furthermore, the energy detection head 11 is electrically connected to the energy processing unit 12 via a matching circuit 121 , and the matching circuit 121 is used to adjust the impedance of the energy detection head 11 so that the impedance of the energy detection head 11 matches the impedance of the energy processing unit 12 .

[0039] In this embodiment, the energy processing unit 12 includes an energy sensor 122, which is electrically connected to the energy detection head 11 and is used to receive harmonic energy from the energy detection head 11. The energy sensor 122 includes an energy receiving chip, which is used to receive the signal adjusted by the matching network.

[0040] In addition, the energy processing unit 12 also includes a signal processing circuit, which is electrically connected to the energy sensor 122 and is used to convert harmonic energy into an electrical signal. Generally speaking, the signal processing circuit can further improve the clarity and accuracy of the signal, which is beneficial to subsequent data processing and analysis.

[0041] For example, an optional signal processing circuit is specifically configured as follows:

[0042] The signal processing circuit includes a harmonic sensor, a low-pass filter, a gain amplifier and a DC bias circuit. The output signal of the harmonic sensor is connected to the input of the low-pass filter, the output of the low-pass filter is connected to the input of the gain amplifier, and the output of the gain amplifier passes through the necessary DC bias circuit to finally output a processed electrical signal.

[0043] Among them, the harmonic sensor is used to capture harmonic energy and convert it into an electrical signal; the low-pass filter is used to filter out the high-frequency signal in the harmonic signal and retain the basic frequency signal, and an RC filter structure can be used; the gain amplifier is used to amplify the filtered signal to increase the signal-to-noise ratio and improve the signal quality; the DC bias circuit is used to convert the signal into a level signal that is easy to digitally process. When necessary, a DC bias circuit can be added to ensure that the signal is within the appropriate working range.

[0044] Based on this, the signal processing circuit can effectively convert the harmonic energy into an electrical signal and obtain an electrical signal suitable for subsequent digital or analog processing.

[0045] In this embodiment, the result output unit 13 includes an encoder 123 and a decoder 124 .

[0046] Specifically, the encoder 123 is used to encode according to the level value of the electrical signal to form intermediate data;

[0047] The decoder 124 is used to decode the intermediate data to obtain an output code corresponding to the current level value of the electrical signal. Different output codes correspond to energy intervals where different harmonic energies are located.

[0048] In addition, the result output unit 13 further includes a signal light component 131 , which is connected to the decoder 124 . The signal light component 131 has a plurality of light-emitting states, and the plurality of light-emitting states correspond one-to-one to the output code of the decoder 124 .

[0049] Optionally, in different lighting states of the signal light assembly 131 , the color, light intensity, or a combination of color and light intensity of the light are different.

[0050] Please refer to Figure 2 , which is an example diagram of energy intensity intervals corresponding to different output codes. In this embodiment, the harmonic energy radiated by the test target is first received by the energy detection head 11, and after being converted into an electrical signal by the energy processing unit 12, the encoder 123 encodes the electrical signals of different levels, and encodes the quantized electrical signal through the encoder 123, and encodes the high level, medium level, and low level into 00, 01, and 10 respectively to control the light-emitting state of the signal light assembly 131; the light of the signal light is controlled through the output end of the decoder 124: when the output ends of the encoder 123 are 00, 01, and 10 respectively, the output ports 1, 2, and 3 corresponding to the decoder 124 are high levels respectively, and the corresponding red light, yellow light, and green light are lit.

[0051] For example, when the output of encoder 123 is 00, it means that the current electrical signal is in the high level range, that is, the margin is less than 6dB; when the output of encoder 123 is 01, it means that the current electrical signal is in the medium level range, that is, the margin is 6-10dB; when the output of encoder 123 is 10, it means that the current electrical signal is in the low level range, that is, the margin is greater than 10dB.

[0052] For example, the lighting states of the signal light assembly 131 corresponding to the high level, medium level and low level are red light, yellow light and green light respectively; it can be understood that the intensity of the harmonic energy can be roughly judged based on the on and off of the red, yellow and green lights. The prototype with the red light on is a high-risk machine and needs to be retested in a third-party laboratory.

[0053] Furthermore, the radiation stray test device provided in this embodiment also includes a gripping handle, the energy detection head 11 is arranged at the end of the gripping handle, and the signal light assembly 131 is arranged on the outer surface of the gripping handle; the gripping handle has a hollow structure, and the energy processing unit 12 is accommodated in the hollow area of ​​the gripping handle.

[0054] By providing a gripping handle, it is convenient to hold the device to test different test targets, thereby improving the convenience of the test.

[0055] In addition, the energy detection head 11 also includes a contact determination end, which is connected to the receiving antenna 111 through a spacer, and the contact determination end is used to contact the test target during the test to determine the starting end of the interval between the receiving antenna 111 and the test target, and the spacer is used to keep the interval between the receiving antenna 111 and the test target consistent during the test. Through the design of the contact determination end and the spacer, the stability and accuracy during the test can be ensured, and the reliability and reproducibility of the test can be improved.

Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
