[0056] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may also be implemented in other embodiments without these specific details.

[0057] It should be understood that when used in the present specification and the appended claims, the term "comprising" indicates the presence of described features, wholes, steps, operations, elements and / or components, but does not exclude the presence or addition of one or more other features, wholes, steps, operations, elements, components and / or combinations thereof.

[0058] It should also be understood that the term “and / or” used in the specification and appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0059] In addition, in the description of the present application specification and the appended claims, the terms "first", "second", "third", etc. are only used to distinguish the descriptions and cannot be understood as indicating or implying relative importance.

[0060] References to "one embodiment" or "some embodiments" etc. described in the specification of this application mean that one or more embodiments of the present application include specific features, structures or characteristics described in conjunction with the embodiment. Therefore, the statements "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. that appear in different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. The terms "including", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized in other ways.

[0061] It is understandable that as there are more and more new-generation chip solution wifi7 products on the market, users are paying more and more attention to the progress of wireless RF testing. The embodiment of the present application takes Qualcomm chip as an example of the chip described in the background technology for explanation. Because there is no automated testing environment for wifi7 in the current conventional way, the wireless RF test of Qualcomm chip solution for wifi7 products has been verified manually before, which requires a lot of human resources. Because wifi7 has three frequency bands of 2.4G, 5G, and 6G, the test items are more and more complex than wifi6. At the same time, when testing the radiated RX sensitivity, it is necessary to complete the conducted TX, conducted RX, and radiated TX tests before testing. Because RF testing is a mandatory test item for all Qualcomm products, it causes great trouble to the testing department and requires a lot of manpower costs.

[0062] In order to solve the above technical problems, the present application provides a testing method, a testing system and a testing terminal, which are mainly used to automatically test the radiation sensitivity of the receiving performance RX of the WiFi7 router to be tested, thereby reducing the detection difficulty and effectively reducing the manpower testing cost.

[0063] Explanation of terms in the manual:

[0064] TX test: The TX in the embodiment of the present application refers to the "transmission performance". The basic test items of TX include output power, power spectrum density, power control, frequency range, adjacent channel power, modulation characteristics, initial carrier tolerance, and carrier frequency offset.

[0065] RX test: RX in the embodiment of the present application refers to "receiving performance". The basic test items of RX are sensitivity, carrier-to-interference ratio performance, blocking performance, intermodulation characteristics and maximum input level.

[0066] refer to Figure 1 , Figure 1 The topological structure diagram of the first embodiment of the test system of the wifi7 router of the embodiment of the present application is as an example but not a limitation. The test system of the present embodiment will be deployed in a shielding room to test the WiFi7 router 04 to be tested in the shielding box 05 in the shielding room. The test system mainly includes a WiFi7 radio frequency tester 01, a switch 02, and a test terminal 03;

[0067] In a specific implementation, the WiFi7 radio frequency tester 01 of this embodiment can preferably use the IQxel-MX test instrument, which has a measurement range of 400MHz to 7300MHz, and can ensure that each wireless device tested meets or even exceeds the strict requirements of 802.11be. The switch 02 of this embodiment preferably uses a gigabit switch, and the switch 02 is connected to the test terminal 03 and the WiFi7 radio frequency tester 01 through a network cable. The test terminal 03 can be a computer device, such as a desktop host, a laptop computer, or a tablet computer; the test terminal 03 is deployed with a first test tool and a second test tool:

[0068] The first test tool is used to provide a service connection between the test terminal 03 and the WiFi7 router 04 to be tested in the shielding box 05. Specifically, QUTS software can be used. QUTS software can provide unified device connection services, provide comprehensive connections and general functions of advanced APIs, and can be used in applications and script clients to provide connection services for communication between the WiFi7 router to be tested and the test terminal.

[0069] The second test tool is used to burn the program, back up the QCN file, and capture the Dump Log Burning: QPST supports flashing the system image via USB, which is a key step in device firmware upgrade or system recovery. Firmware upgrades help solve device performance issues, fix security vulnerabilities, or introduce new features. Back up QCN files: QCN files store some important data of the device, including IMEI numbers. The QPST tool can easily back up and restore QCN files, which is essential for device repair and recovery. During the flashing process, if the IMEI number is lost or flashed incorrectly, the device will not work properly. Therefore, it is wise to back up the QCN file before flashing. Capture Dump Log: Dump Log is a memory dump file generated by the device when a problem occurs, which contains rich debugging information. The QPST tool allows developers or technicians to capture the Dump Log of the device under specific conditions, which helps to quickly locate the problem and fix it. The process of capturing Dump Log usually needs to be performed after the device enables Dump mode, which can be enabled through AT commands or burning fsc.bin files.

[0070] The test terminal 03 is connected to the WiFi7 radio frequency tester 01 (IQxel-MX) through a first IP address, and the test terminal 03 is connected to the WiFi7 router 04 to be tested through a second IP address;

[0071] The WiFi7 radio frequency tester 01 (IQxel-MX) can be connected to the shielding box 05 via a radio frequency cable, and the WiFi7 radio frequency tester 01 tests the radiation sensitivity of the WiFi7 router 04 to be tested based on the tri-band antenna 06 in the shielding box 05.

[0072] refer to Figure 3 , Figure 3 A flow chart of a test method provided by the present application is shown, and the test method mainly includes steps S10 to S30:

[0073] Step S10: Determine the conducted emission performance of the WiFi7 router to be tested;

[0074] In the above step S10, this embodiment determines the conducted transmission performance of the WiFi7 router to be tested through a conducted test system (hereinafter referred to as "conducted TX" as the abbreviation of "conducted transmission performance"); Figure 2 As shown, Figure 2 The conductive test system of the embodiment of the present application is mainly used to perform conductive TX / RX test on a Wifi7 router developed using a new generation chip (Qualcomm chip in this embodiment is used as an example). It can be used to test conductive TX and RX. The instruments involved include a WiFi7 radio frequency tester (IQxel-MX, an instrument supporting WiFi7, is used in this embodiment), a switch (a gigabit switch is used in this embodiment), a test terminal (a desktop computer or a laptop computer can be used in this embodiment) with a first test tool (QUTS of Qualcomm tool is used in this embodiment as an example) and a second test tool (QPST of Qualcomm tool is used in this embodiment) installed, a bare board 041 of the WiFi7 router to be tested in a shielding box (i.e., a bare board of a router supporting WiFi7), a shielding box, a shielding room, and a number of network cables, radio frequency cables, etc. are also required. All of the above test equipment and instruments can be used together with Figure 2 The test equipment and instruments in the radiation test system are shared. The bare board of the WiFi7 router is the original WiFi7 router to be tested with the shell removed. Figure 1The biggest difference is that the three-band antenna is replaced with a radio frequency line. The IP address of the router that supports WiFi7 is set to 192.168.1.1. The WiFi7 radio frequency tester (IQxel-MX instrument) is connected to the switch via a network cable, and the IP address of the WiFi7 radio frequency tester is set to 192.168.100.254. The test terminal PC1 is connected to the switch via a network cable. The network card of the test terminal PC1 is set with two IP addresses (i.e., the first IP address and the second IP address). The first IP address is set to 192.168.100.25, which is only used to communicate with the WiFi7 radio frequency tester (IQxel-MX instrument). The second IP address is set to 192.168.1.27, which is mainly used to communicate with the bare board of the WiFi7 router to be tested. The WiFi7 radio frequency tester (IQxel-MX instrument) can be connected to the shielding box by means of a radio frequency line, and then connected to the shielding box by means of the radio frequency line and The bare board connection of the WiFi7 router to be tested, because the number of antennas of 2.4G, 5G, and 6G WiFi7 routers on the market is at least 2 antennas, for the convenience of testing, the embodiment of the present application can use a 1-to-4 power splitter to test the conducted TX (conducted transmission performance) and conducted RX (conducted receiving performance) of the WiFi7 router, and multiple antennas can be tested together, because it is necessary to calculate the radiation line loss compensation first, and it is necessary to test the conducted TX and RX. The conducted TX is mainly used to calculate the radiation line loss compensation, and the conducted RX is mainly to verify whether the tested radiation RX sensitivity value is correct. If the radiation RX sensitivity deteriorates by more than 3db compared with the conducted RX, such as the tested conducted RX sensitivity value of the 5G band 11a mode MCS0 is -96dbm, and the tested radiation RX sensitivity value of the 5G band 11a mode MCS0 is -91dbm, then it can be determined that the radiation RX sensitivity data is abnormal.

[0075] In the specific implementation, the test method of the conducted TX in the embodiment of the present application takes 2.4G as an example. First, the line loss compensation must be calibrated, which is mainly completed through the company's self-developed automation tools. The line loss compensation verified in this embodiment is as follows: the normal 1-to-4 power divider plus 2 1.5-meter RF lines calibrated out a 2.4G line loss compensation of about 20db, a 5G line loss compensation of about 23db, and a 6G line loss compensation of about 24db.

[0076] The calibrated line loss compensation also needs to be converted into the line loss compensation file in .xml format of Qualcomm product solution. For example, in the line loss compensation file in .xml format <pathname> WCD1< / pathname>WCD1 represents the line loss compensation value of 2.4G, 5G, and 6G frequency bands under antenna 1, WCD2 represents the line loss compensation value of 2.4G, 5G, and 6G frequency bands under antenna 2, WCD3 represents the line loss compensation value of 2.4G, 5G, and 6G frequency bands under antenna 3, and WCD4 represents the line loss compensation value of 2.4G, 5G, and 6G frequency bands under antenna 4.

[0077] like Figure 2 As shown, connect the RF line and the 2.4G interface of the single board of the device under test (WiFi7 router to be tested) through a button line, first open the QUTS tool software, create a TCP connection with port 2500, and then manually log in to the device under test through telnet or ssh to connect the instrument by issuing instructions. The 192.168.1.27 address in the issued instructions is the IP address of the network card of the test terminal connected to the router. When the instrument and the device under test are successfully connected, we can see the relevant successful connection information.

[0078] Furthermore, line loss calibration and compensation are also required: connect both ends of the cable to the transmit and receive ports of the WiFi7 RF tester. Generally speaking, a fixed attenuation will be connected to prevent the device under test from damaging the WiFi7 RF tester due to excessive power. The maximum input power of the WiFi7 RF tester is 25dBm, while the maximum power of the device under test in this application may reach 30dBm. If no fixed attenuation is added to the Cable line, and the attenuation of the Cable is only a few dB, the input power may exceed 25dBm and damage the test instrument. In addition, the transmit port and receive port of the WiFi7 RF tester port instrument need to be configured in a preset manner; then, edit the instrument configuration information of the WiFi7 RF tester.

[0079] It is understandable that in a specific implementation, the prerequisites for the conduction test system of the embodiment of the present application to test the conduction TX mainly include the following parts:

[0080] 1. A series of software including Qualcomm's QUTS (first test tool) and QPST (second test tool) have been installed on the test terminal 03;

[0081] 2. Use the QUTS tool to connect the computer to the WiFi router 04 to be tested, connect normally through the TCP protocol, the TCP port is 2500, manually log in to the WiFi router 04 to be tested through telnet or ssh, connect by issuing instructions, and use socket for communication, which is mainly used for automation tools to control the transmit and receive power usage of the WiFi router 04 to be tested.

[0082] 3. The automated script for testing the conductive TX has been configured on the QPST;

[0083] 4. The equipment wiring has been Figure 3 The topology diagram is connected well, and the test terminal 03 can normally access the WiFi router 04 and the instrument under test;

[0084] 5. The conducted line loss compensation has been calibrated using an automated tool and filled into a line loss file with a .xml suffix, such as pathloss_wcd.xml;

[0085] 6. The instrument's IP address and the RF port used for testing have been correctly written into the configuration file with the .xml suffix, such as LP_IQxel80_100.254.xml.

[0086] Furthermore, when the relevant test personnel use the test terminal 03 to perform the conducted TX test on the WiFi router 04 to be tested, they can open the automated tool deployed on the test terminal 03, check the conducted TX test item to be tested, and take the 2.4G radiation RX sensitivity test as an example in this embodiment. Only the 2.4G conducted TX test item is checked. After clicking the start button, the automated tool will first read the IP address and RF radio port in LP_IQxel80_100.254.xml, and then find the corresponding line loss compensation value from the line loss configuration file pathloss_wcd.xml. The line loss configuration file pathloss_wcd.xml table is mainly located by parameters such as channel, rate, mode, antenna, etc., and needs to correspond to the TX result of the last test. Figure 4 shown.

[0087] Furthermore, the automation tool of the test terminal 03 controls the transmission power of the WiFi router 04 to be tested through QUTS, and transmits it according to the first test parameters (including at least channel, rate, mode, antenna and other parameters) configured in advance on QPST. Then, the automation tool calls TILIB through QSPR to control the Iqxel MW instrument (WiFi7 RF tester 01) to receive the corresponding power and EVM, etc. TILIB mainly provides a test equipment automation library for QSPR RF testing. Finally, the collected power and EVM information are archived in the form of logs. When the relevant testers complete the test, they only need to manually convert it into Excel table format (reference Figure 5 ); the corresponding generated transmission TX data format can be referred to Figure 6 .

[0088] Step S20: Determine the radiation emission performance of the WiFi7 router to be tested;

[0089] In the above step S20, this embodiment determines the radiation transmission performance of the WiFi7 router to be tested through the radiation test system (hereinafter referred to as "radiation TX" as the abbreviation of "radiation transmission performance");

[0090] Specifically, taking 2.4G as an example, the radiation test system used in step S20 is Figure 1 The test system is the same; Figure 1 This is the Wifi7 router Qualcomm solution radiation TX / RX test topology diagram, which can be used to test radiation sensitivity and radiation TX, such as Figure 1As shown, the instruments involved include an IQxel-MX instrument that supports WiFi7, a Gigabit switch, a QUTS and QPST computer with Qualcomm tools installed, a router that supports WiFi7, a shielding box, and a shielding room. At the same time, several network cables, RF cables, tri-band antennas, etc. are also required. The IP address of the router that supports WiFi7 is set to 192.168.1.1. The IQxel-MX instrument is connected to the switch via a network cable, and the IP address of the instrument is set to 192.168.100.254. PC1 is connected to the switch via a network cable. The network card of PC1 has two IP addresses, one of which is set to 192.168.100.25, which is used to communicate with the IQxel-MX instrument, and the other IP address is set to 192.168.1.27, which is mainly used to communicate with the WiFi7 router. The IQxel-MX instrument is connected to the shielding box via a radio frequency cable, and then the radiation sensitivity of the WiFi7 router is tested through a tri-band antenna. Before testing, line loss compensation needs to be added, otherwise the data cannot be tested normally. Since the line loss compensation of radiation TX cannot be directly verified like conduction TX, it needs to be directly calculated through the protocol. Normally, we set the line loss compensation of 2.4G to 40dbm, the line loss compensation of 5G to 45dbm, and the line loss compensation of 6G to 50dbm. The antenna of the IQxel instrument and the antenna of the Wifi7 router are about 1 meter apart. Then the attenuation of radio waves in the air for 1 meter can be calculated using the following formula: wireless theoretical attenuation value = 32.4 + 20logf (Mhz) + 20logd (km). Putting the distance and frequency band into the formula, the tester can get that the theoretical attenuation of 2.4G at a distance of 1 meter is 32.4 + 20log (2483) + 20log (0.001) = 40.2dbm, and the theoretical attenuation of 5G is 32.4 + 20log (5850). +20log(0.001)=47.7dbm, 6G theoretical attenuation=32.4+20log(7250)+20log(0.001)=49.6dbm, testers can roughly estimate that 2.4G can manually add 40dB line loss compensation, 5G can roughly add 45dB line loss compensation, and 6G can roughly add 50dB line loss compensation, so the final line loss compensation of RX radiation sensitivity in 2.4G mode=conducted TX value-radiated TX value+40dB, line loss compensation of RX radiation sensitivity in 5G mode=conducted TX value-radiated TX value+45dB, line loss compensation of RX radiation sensitivity in 6G mode=conducted TX value-radiated TX value+50dB, the test methods of radiation TX and conduction TX are basically similar, the main difference is that the line loss compensation and connection method are different, and finally the test data of conduction TX and radiation TX tested in this embodiment are as follows: Figure 7 shown.

[0091] Furthermore, in some embodiments, Figure 2 The conducted test system shown is also used to test the conducted RX (conducted receiving performance) of the WiFi7 router to be tested, and the conducted RX is used as an auxiliary test of the RX radiation sensitivity: the conducted receiving performance of the WiFi7 router to be tested is determined by the conducted test system; the conducted receiving performance of the WiFi7 router to be tested is compared with the conducted transmitting performance to obtain a comparison result; when the comparison result meets the preset conditions, it is determined that the radiation sensitivity of the WiFi7 router to be tested meets the test requirements.

[0092] The "comparison results" and "preset conditions" in the above steps can be determined through the following embodiments. For example, since the value obtained by the radiation RX sensitivity test in this embodiment needs to be no more than 3db worse than the conducted RX test value, and the sensitivity must be worse than the conducted sensitivity to pass the test, the conducted RX sensitivity under different test environments may differ by 1 to 2db. In order to make the test results more accurate, it is generally necessary to test the conducted RX and radiation RX sensitivities in the same environment so that the comparison is meaningful.

[0093] This embodiment tests the RX radiation sensitivity mainly to test the minimum receiving sensitivity (Receiver minimum receive level sensitivity): receiving sensitivity is the most important indicator of the receiver. The better the receiving sensitivity, the smaller the signal that can be received, which means the longer the receiving distance of the DUT, and the larger the wireless coverage of the DUT. Use IQ to transmit a certain number of data packet files. If the packet loss rate is less than 10% (11b is less than 8%), continue to reduce the transmission power. If it is greater than 10% (11b is greater than 8%), increase the transmission power. Find the minimum power that meets the packet loss rate condition, which is the minimum receiving sensitivity of the DUT.

[0094] Step S30: Determine the line loss compensation of the radiation sensitivity of the WiFi7 router to be tested based on the conducted emission performance and the radiated emission performance, wherein the line loss compensation of the radiation sensitivity is used to test the radiation sensitivity of the WiFi7 router to be tested.

[0095] It is understandable that after the tester has obtained the test values ​​of conducted TX, conducted RX, and radiated TX, he can start testing the radiated RX sensitivity. The test method of radiated RX sensitivity is similar to that of conducted RX. The main difference is that the connection method and line loss compensation are inconsistent. When testing conducted RX, the connection method is as follows: Figure 2 As shown, the radiated RX sensitivity is connected as Figure 1As shown, the line loss compensation of conducted RX is shared with conducted TX, while the line loss compensation of radiated RX is: 2.4G mode RX radiation sensitivity line loss compensation = conducted TX value - radiated TX value + 40dB, 5G mode RX radiation sensitivity line loss compensation = conducted TX value - radiated TX value + 45dB, 6G mode RX radiation sensitivity line loss compensation = conducted TX value - radiated TX value + 50dB, so the tester can finally get the radiation RX sensitivity line loss compensation as shown in the following table.

[0096] Finally, the tester can replace the line loss compensation file of the conducted RX with the calculated line loss compensation generated in XML file format, and then trigger the test start button on the running test terminal to start the automated test. Finally, the tester can compare the value obtained from the radiation RX sensitivity test with the conduction RX test value. The test is considered passed only when the value obtained from the radiation RX sensitivity test is within 3db worse than the conduction RX test value and the radiation sensitivity must be worse than the conduction sensitivity (corresponding to the "preset condition" in the claims). Figure 8 The test values ​​in the table shown are the results of the test passing.
