[0002] Most of the current line loss inspections are based on the Golden Machine, and the actual environment line loss is calculated by comparing the difference with the Golden Machine. This method first prepares an RF line with known line loss, and sets the known line loss to the line loss file according to different frequencies; then uses the known line loss to test the Golden Machine, obtains the power of the Golden Machine at each frequency point to be tested in the current environment, and regards it as the true power of the Golden Machine and saves it in the line loss file; finally, places the Golden Machine in the actual test environment, sets the line loss of the test environment to the known line loss, tests the power of each frequency point to be tested, calculates the difference between the power of each point at this time and the corresponding power saved previously, and adds the corresponding known line loss saved previously as the line loss value of the actual environment, and saves it again in the line loss file.

[0003] The accuracy of the line loss value obtained by the above-mentioned line loss inspection method depends on the accuracy of the known line loss and the stability of the gold machine. The internal loss of the RF interface input and output of different instruments is different. This internal loss is not compensated in the line loss file, so there will be a certain error.

[0027] In order to facilitate the understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present application more thorough and comprehensive.

[0028] See also Figure 1 , a line loss inspection method, comprising step S200, step S300 and step S500.

[0029] Step S200: When the power meter is connected to the RF port of the comprehensive tester, the frequency points that need to be used corresponding to the RF port are traversed to obtain the corresponding downlink internal loss value of the RF port at each frequency point.

[0030] Specifically, the present application uses an actual use environment in which one RF line is connected to the first RF port of the comprehensive tester, and the other is connected to the second RF port of the comprehensive tester to perform a similar spot inspection scheme analysis. The power meter is connected to the RF port of the comprehensive tester, that is, the power meter is directly connected to the RF port of the comprehensive tester. At this time, the power of the RF signal output by the comprehensive tester can be directly measured by the power meter, and when the comprehensive tester sends the RF signal, the signal itself has a certain amount of transmission power. The controller subtracts the power value measured by the power meter from the transmission power, and the loss of the RF signal at the RF port can be obtained, that is, the downlink internal loss value. During the use of the comprehensive tester, the frequency of the signal received or sent by the RF port is not unique. At different signal frequency sizes, the corresponding downlink internal loss values ​​will also be different. Therefore, in this embodiment, the controller will traverse all frequency points that the RF port needs to use, and measure and analyze the corresponding downlink internal loss value at each frequency point.

[0031] It should be noted that, in one embodiment, the power meter is connected to the comprehensive tester by a switch signal sent by the controller, so that the corresponding line is turned on. In another embodiment, this part of the access operation can be manually operated by the user. After the controller detects that the RF port of the comprehensive tester is connected to the power meter, it will traverse the frequency points corresponding to the RF port to be used according to the internal program of the device, and obtain the corresponding downlink internal loss value of the RF port at each frequency point.

[0032] It can be understood that the type of comprehensive tester is not unique, as long as it is a measuring instrument with RF signal input and output functions. For example, in one embodiment, the comprehensive tester adopts the CMW500 model comprehensive tester. Similarly, the type of power meter is not unique. In one embodiment, it can be implemented by using an NRP model power meter. Correspondingly, when the comprehensive tester adopts the CMW500 model comprehensive tester, there will be three RF ports, including RF1COM port, RF2COM port and RF1OUT port, all of which can output and adjust continuous sine waves or input signals for testing. In order to facilitate the understanding of the various embodiments of the present application, in a more detailed embodiment, the comprehensive tester adopts the CMW500 model comprehensive tester, and the power meter also adopts the NRP model power meter. At the same time, the RF port of the comprehensive tester adopts the RF1COM port as the first RF port and the RF1OUT port as the second RF port to realize line loss inspection.

[0033] Step S300: when the RF line is connected between the RF port and the power meter, the line loss value of the RF line is obtained according to the downlink internal loss value analysis.

[0034] Specifically, when the RF line is connected between the RF port and the power meter, that is, the RF signal output by the RF port will experience the internal loss of the RF port and the loss of the RF line, and will eventually be measured by the power meter. Therefore, based on the downlink internal loss value that has been measured and analyzed in the above steps, it is only necessary to obtain the power measurement value of the power meter for analysis, that is, the attenuation of the RF signal passing through the RF line, that is, the line loss value. Similarly, since there are multiple frequency points used by the RF port of the comprehensive tester, for each frequency point, the corresponding line loss value is obtained based on the downlink internal loss value corresponding to the frequency point and the power value measured by the power meter. The specific analysis method is that the controller obtains the power value C measured by the power meter, and then uses the transmission power A at the frequency point to subtract the downlink internal loss value B corresponding to the frequency point, and then subtracts the power value C, that is, the line loss value X corresponding to the frequency point can be obtained, that is, X=ABC.

[0035] Step S500, analyzing the downlink internal loss value and the line loss value to obtain the uplink and downlink losses from the fixture to the comprehensive tester.

[0036] Specifically, the fixture is connected to the RF port of the comprehensive tester, the gold machine board is set on the fixture, and the gold machine board is connected to the power meter through the RF line. The uplink and downlink losses from the fixture to the comprehensive tester are the uplink loss from the fixture to the comprehensive tester and the downlink loss from the fixture to the comprehensive tester. For different RF ports, the types of loss values ​​that need to be measured will also be different. For the RF1COM signal port, since it can both transmit and receive RF signals, the corresponding frequency points that need to be used include both downlink frequencies and uplink frequencies. Therefore, the loss value from the fixture to the comprehensive tester measured at this time includes both the uplink loss from the fixture to the comprehensive tester and the downlink loss from the fixture to the comprehensive tester. For the RF1COM signal port, the frequency it needs to use is only the downlink frequency, and the corresponding loss value from the fixture to the comprehensive tester is the downlink loss from the fixture to the comprehensive tester.

[0037] It can be understood that in this embodiment, the Jinji board is regarded as one end of the RF line. The line loss value of the Jinji board can be obtained in advance by testing with a network analyzer and pre-stored in the controller in a preset form. When the controller performs uplink and downlink loss analysis from the fixture to the comprehensive tester based on the downlink internal loss value and the line loss value, in order to further ensure the accuracy of the loss analysis, the line loss value of the Jinji board will be introduced. During the analysis process, the line loss value of the Jinji board will be removed to obtain a more accurate uplink and downlink loss from the fixture to the comprehensive tester.

[0038] Therefore, in one embodiment, before step S500, the method further includes the step of obtaining the line loss value of the Jinji board. The line loss value of the Jinji board is measured by the network analyzer S21. The specific measurement method is: first, use standard parts to perform a dual-port calibration operation of the network analyzer; then set the network analysis start and stop frequencies to cover all frequency points, connect the Jinji board to perform S21 calibration, and read the insertion loss of each frequency point, that is, the line loss value of the Jinji board.

[0039] See also Figure 2 In one embodiment, the RF port includes a first RF port and a second RF port, and step S200 includes step S210 and step S220.

[0040] Step S210, when the power meter is connected to the first RF port, the frequency points that need to be used by the first RF port are traversed to obtain the corresponding downlink internal loss value of the first RF port at each frequency point; Step S220, when the power meter is connected to the second RF port, the frequency points that need to be used by the second RF port are traversed to obtain the corresponding downlink internal loss value of the second RF port at each frequency point.

[0041] Specifically, as shown in the above embodiment, the comprehensive tester adopts the CMW500 model comprehensive tester, the corresponding first RF port is the RF1COM port, and the second RF port is the RF1OUT port. At this time, a power meter is respectively connected to the RF1COM port and the RF1OUT port, and all frequency points required to be used by each port are traversed. According to the power value collected and sent by the power meter under various circumstances, and the transmission power of the RF signal transmitted by the comprehensive tester under various circumstances, the corresponding downlink frequency of the RF1COM port or the RF1OUT port at each frequency point can be obtained.

[0042] It should be pointed out that, in one embodiment, since the output signal of the second RF port is needed to be used when testing and analyzing the uplink internal loss of the first RF port, it is necessary to ensure that the corresponding downlink internal loss value is calculated for each uplink frequency in the RF point of the first RF port in the downlink internal loss value test of the second RF port, so as to subsequently perform the uplink internal loss value analysis and calculation of the first RF port.

[0043] See also Figure 3 In one embodiment, step S210 includes step S211, step S212 and step S213.

[0044] Step S211, when the power meter is connected to the first RF port, control the first RF port to output a continuous sine wave that matches the frequency point that the first RF port needs to use; step S212, obtain the first power measurement value corresponding to each frequency point; step S213, analyze according to the first power measurement value and the transmission power of the corresponding continuous sine wave to obtain the downlink internal loss value corresponding to the first RF port at each frequency point.

[0045] Specifically, at this time, the first RF port is used as the RF signal transmission port, and all the frequency points that the first RF port needs to use are traversed, that is, the RF port is controlled to output the RF signal of the corresponding transmission power (or frequency) according to each frequency point. In this embodiment, the comprehensive tester is controlled to output a sinusoidal signal matching each frequency point. The signal reaches the power meter after attenuation of the first RF port. The power meter will measure the first power measurement value. It only needs to subtract the transmission power of the signal from the first power measurement value to obtain the attenuation of the signal when passing through the first RF port, that is, the corresponding downlink internal loss value. Using the same method, the controller sequentially outputs continuous sinusoidal waveforms of corresponding sizes of the frequency points for analysis and calculation, and the downlink internal loss value analysis operation of the first RF port can be completed.

[0046] See also Figure 4 In one embodiment, step S220 includes step S221, step S222 and step S223.

[0047] Step S221, when the power meter is connected to the second RF port, control the second RF port to output a continuous sine wave that matches the frequency point that the second RF port needs to use; step S222, obtain the corresponding second power measurement value at each frequency point; step S223, analyze according to the second power measurement value and the transmission power of the corresponding continuous sine wave to obtain the corresponding downlink internal loss value of the second RF port at each frequency point.

[0048] Specifically, similar to the above-mentioned downlink internal loss value analysis operation of the first RF port, at this time, the second RF port is used as the output port of the RF signal. It is only necessary to calculate the difference between the transmission power of the RF signal and the second power measurement value measured by the power meter to obtain the downlink internal loss value of the second RF port at the corresponding frequency point. The control tester outputs a sinusoidal signal that matches each frequency point. The signal reaches the power meter after attenuation at the second RF port. The power meter will measure the second power measurement value. It is only necessary to subtract the transmission power of the signal from the second power measurement value to obtain the attenuation of the signal when passing through the second RF port, that is, the corresponding downlink internal loss value. Using the same method, the controller sequentially outputs continuous sinusoidal waveforms of corresponding sizes at the frequency points for analysis and calculation, and the downlink internal loss value analysis operation of the second RF port can be completed.

[0049] See also Figure 5 In one embodiment, after step S300 and before step S500, the method further includes step S400. Step S500 includes step S510.

[0050] Step S400, when the RF line connects the first RF port and the second RF port, the corresponding uplink internal loss value of the first RF port at each frequency point is obtained by analyzing the corresponding downlink internal loss value and line loss value of the second RF port at each frequency point.

[0051] Step S510, analyzing the downlink internal loss value, the uplink internal loss value and the line loss value to obtain the uplink and downlink losses from the fixture to the comprehensive tester.

[0052] Specifically, in this embodiment, the first RF port is used as a signal receiving port, and the second RF port is used as a signal transmitting port, and the uplink internal loss value of the first RF port is analyzed, that is, the signal attenuation caused when the first RF port receives the RF signal. The specific operation is to connect the first RF port with the second RF port using an RF line, and control the second RF port of the comprehensive tester to output an RF signal of corresponding transmission power. After the RF signal passes through the downlink loss of the second RF port, the line loss of the RF line, and the uplink loss of the first RF port, a RF signal of corresponding size is obtained. At this time, the corresponding downlink internal loss value is the downlink internal loss value of the second RF port. The comprehensive tester itself has the function of receiving RF signals. When the comprehensive tester receives the RF signal, it can simultaneously detect the measured power of the signal. The controller only needs to subtract the measured power, the downlink internal loss value of the second RF port, and the line loss value of the RF line from the transmission power. The final value is the uplink internal loss value of the first RF port.

[0053] Correspondingly, in this embodiment, after analyzing and obtaining the uplink internal loss value of the first RF port, in subsequent operations, the fixture is connected to the RF port of the comprehensive tester, the gold machine board is set on the fixture, and the gold machine board is connected to the power meter through the RF line, that is, the uplink loss analysis from the fixture to the comprehensive tester can be realized in combination with the uplink internal loss value. The specific analysis method is similar to the above, and only needs to use the transmission power of the RF signal minus the loss value from the fixture to the comprehensive tester during the signal transmission process, and the actual power value obtained by the final measurement, that is, the uplink loss value from the fixture to the comprehensive tester can be obtained.

[0054] It can be understood that by connecting the fixture to different RF ports in a similar manner, the downlink loss from the fixture to the first RF port of the comprehensive tester and the downlink loss from the fixture to the second RF port of the comprehensive tester can be analyzed. Taking the measurement of the downlink loss of the first RF port of the comprehensive tester as an example, the first RF port is used as the signal transmitting end. The RF signal sent by the port passes through the downlink internal loss of the first RF port, the downlink loss from the fixture to the first RF port of the comprehensive tester, the line loss of the gold machine board (as shown in the above embodiment, which can be obtained by a network analyzer), and the RF line loss in sequence. Finally, a power measured value is obtained by measuring with a power meter. In this process, only the downlink loss from the fixture to the first RF port of the comprehensive tester is unknown. The downlink loss from the fixture to the first RF port of the comprehensive tester is obtained by subtracting the loss of the rest of the transmission power.

[0055] Further, in one embodiment, see Figure 6 In one embodiment, before step S200, the method further includes step S100.

[0056] Step S100, clearing and calibrating the power meter. In this embodiment, when performing line loss spot inspections at various locations, the power meter is first cleared and calibrated, which can effectively ensure the accuracy of the actual power measurement value, and further ensure the accuracy of each line loss value obtained by the final line loss spot inspection.

[0057] After obtaining the loss values ​​of each part at each required frequency point through the above scheme, if it is necessary to perform a spot check on the line loss of the RF line, it is only necessary to connect the fixture to the RF port of the comprehensive tester, set the gold machine board on the fixture, and connect the gold machine board to the power meter through the RF line to be tested. Since the uplink and downlink losses from the fixture to the comprehensive tester, the downlink internal loss value of the RF port, and the line loss value of the gold machine board are all analyzed through the above embodiment, the power meter can also realize the power measurement operation of the final received RF signal, and the transmission power corresponding to each frequency point is also known. The line loss value of the RF line to be tested can be obtained by subtracting the uplink and downlink losses of the comprehensive tester, the downlink internal loss value of the RF port, the line loss value of the gold machine board, and the actual power measured value from the transmission power. Through this scheme, it is only necessary to adjust the frequency of the output RF signal to traverse each frequency point to be tested, and the spot check operation of the RF line to be tested can be realized.

[0058] The above-mentioned line loss inspection method uses a comprehensive tester as a signal source and power measurement terminal, and uses a power meter as an auxiliary power measurement terminal. First, when the power meter is connected to the RF port of the comprehensive tester, the corresponding downlink internal loss value of the RF port at each frequency point is measured and analyzed; then, when the RF line is connected between the RF port and the power meter, the line loss value of the RF line is analyzed; finally, when the fixture is connected to the RF port of the comprehensive tester, the gold machine board is set on the fixture, and the gold machine board is connected to the power meter through the RF line, the uplink and downlink losses from the fixture to the comprehensive tester are obtained by combining the downlink internal loss value and the line loss value. This solution can accurately calculate the corresponding loss of each actual connection component at each frequency point of use, so that the loss of the entire link at this frequency point can be accurately calculated, and the loss of each frequency point can be verified. This solution does not rely on the gold machine or the platform, which better guarantees the accuracy of the line loss; at the same time, this solution can be implemented automatically, does not require users to manually record and calculate, is easy to repeat and will not make mistakes.
