Description

Technical Field

[0001] The present specification relates to the field of financial technology, and in particular to a general network equipment radio frequency testing system and method. Background Art

[0002] In recent years, with the rapid growth of mobile services, the communications industry has developed rapidly. In order to solve the problem of mobile network coverage, various network equipment such as base stations, repeaters, satellite earth stations, etc. have been continuously updated, resulting in a gradual increase in the workload of equipment testing. The RF testing of such network equipment involves many steps, and the testing work is highly comprehensive. Traditional testing is usually based on manual testing or the use of an interface box with the function of testing a single network device. This interface box has a single function and limitations. It lacks flexibility and cannot meet the needs of various network equipment RF testing scenarios, which to a certain extent causes waste of resources and unreasonable use.

[0003] Communications testers use RF cables to connect the external RF interface of an interface box with a single test scenario to the test instrument, and then send instructions to the interface box through the control PC to switch the internal test line, forming a path that meets the test requirements, and finally conduct relevant RF tests.

[0004] Since the interface box only has a single test scenario, it has great limitations, lacks flexibility, and cannot meet other test requirements. The RF cable connected to the external RF interface of the interface box needs to be disassembled when there are other test requirements, resulting in different RF cables used in the interface box each time, which is prone to loosening and damage at the interface, increasing the uncertainty of the RF cable standing wave ratio and insertion loss, affecting the accuracy and reproducibility of the test results. It does not have a reverse signal detection function, and it is easy to have a test hazard that the device under test mistakenly sends a high-power RF signal and reversely inputs it to the signal source, causing damage to the instrument. Therefore, the disadvantages of this existing technical solution are that the test scenario is single, resulting in a waste of resources, and there are test hazards during operation, and the uncertainty of RF cable parameters interferes with the test results.

Obviously, the described embodiments are only part of the embodiments of this specification, not all of the embodiments. Based on the embodiments in this specification, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this specification.

[0077] It should be noted that the terms "first", "second", etc. in the description and claims of this specification and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of this specification described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, device, product or equipment that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or equipment.

[0078] This specification provides method operation steps as described in the embodiments or flow charts, but more or fewer operation steps may be included based on routine or non-creative work. The order of steps listed in the embodiments is only one way of executing the order of many steps and does not represent the only execution order.

[0079] It should be noted that the general network equipment RF testing system and method of this specification can be used in the field of communication technology, and can also be used in the field of network equipment testing. This specification does not limit the application field of the general network equipment RF testing system and method.

[0080] Figure 1The diagram shows a general network device radio frequency test system according to an embodiment of the present specification, which specifically includes: a signal source port 100, a coupling unit 200, a signal processing unit 300, a control unit 400 and a plurality of input ports 500. The control unit 400 (not shown in the figure) includes a plurality of digital switches, the coupling unit 200 includes a plurality of couplers, and the signal processing unit 300 includes at least a filter or an attenuator.

[0081] The signal source port 100 is used to receive a signal from a signal source, and the signal source port 100 is connected to an input port 500 through a control unit 400 and a coupling unit 200. The coupling unit 200 is used to couple and transmit a signal received by at least one signal source port to at least one input port 500. The control unit 400 is used to respond to a control instruction and switch the connection line between the signal source port 100 and the coupling unit 200, the signal processing unit 300 and the input port 500. The multiple input ports 500 are used to send the signal from the signal source to a device under test connected to the system.

[0082] The signal processing unit 300 includes a filter and an attenuator. The attenuator prevents different high-power signals from being directly input into the test instrument, thereby preventing the RF signal from burning the instrument. The attenuator is used to control the signal energy by reducing the amplitude of the uplink signal emitted by the signal source or the amplitude of the downlink signal emitted by the device under test; the filter controls the frequency distribution range of the signal by selecting a specific frequency range, and the band-stop filter can effectively filter useful signals with a frequency of Sub6G to prevent the interference of useful signals from affecting the test results.

[0083] The filter in this specification is a band-stop filter. According to the device type and characteristics of the device to be tested, a variety of band-stop filters of different frequency bands are set to remove the high-frequency or low-frequency signal components that are not needed by the filter to obtain a signal in a specific frequency band. In this specification, the general network equipment RF test system has built-in filters and attenuators required for testing to avoid testers manually connecting auxiliary equipment. The signal processing unit 300 is built into the network equipment RF test system, and the connection switching can be automatically completed according to the test requirements, which plays the role of testing with the least RF devices and RF cables, and has the function of not needing to manually replace attenuators, filters and RF cables in the same test scenario.

[0084] In the embodiments of this specification, the front panel of the universal network equipment RF test system is integrated with the RF interface of the device under test and the test instrument, which is convenient for cable connection. At the same time, all the RF interfaces connecting the device under test and the test instrument outside the platform are uniformly designed on the front panel, and low-attenuation and low-standing-wave RF cables that meet the needs of multiple test scenarios are customized. The dedicated line does not need to be disassembled, and has the characteristics of smaller insertion loss, standing wave ratio, and preventing power leakage caused by damage to the RF interface due to multiple disassembly, which further reduces the test cost and improves the accuracy and reproducibility of the test results.

[0085] like Figure 2 The front structure diagram of the external structure of a universal network equipment RF test platform in the embodiment of this specification is shown. All the interfaces of the connected devices under test and the RF interfaces of the test instruments are integrated on the front panel of the network equipment RF test system, which has the characteristics of rich external RF interfaces and can connect multiple devices. It can further reduce the manual operation of the test personnel and facilitate the test personnel to observe the connection status of all external RF interfaces.

[0086] Figure 2 The structure is based on 3GPP standards and combined with independent design and optimization, and its internal RF components are superimposed and coupled, which can not only meet a variety of test scenarios, but also have the characteristics of testing with the shortest line and the least RF components, saving resources and compressing the volume to the greatest extent. The coupler inside the system can combine the two RF signals output simultaneously by the signal source into one RF signal and input it to the device under test, providing a solution for simultaneously outputting multiple RF signals to a single-channel device or inputting one RF signal to a multi-channel device.

[0087] exist Figures 3 to 5 In the schematic diagram shown, the signal source port 100 includes: a dual-channel signal source port 110, a first single-channel signal source port 120, and a second single-channel signal source port 130. The dual-channel signal source port 110 includes a dual-channel signal source first port 111 and a dual-channel signal source second port 112. The front panel of the network equipment RF test system is provided with a dual-channel signal source port 110, a first single-channel signal source port 120, and a second single-channel signal source port 130, which can simultaneously connect a dual-channel vector signal source / vector network analyzer to connect the signal source and two single-channel single-tone signal sources. In addition, a spectrum analyzer port is provided on the front panel of the general network equipment RF test system, which can be connected to a spectrum analyzer. Furthermore, the front panel of the network equipment RF test system is provided with an input port 500 ( Figure 2The tester is connected to the RF port of the external device under test through the input port 500. The input port 500 includes three ports, namely, a first input port 510, a second input port 520 and a third input port 530. A three-color indicator light that can be customized is provided next to each input port. The tester can control the logic of the indicator light on and off according to their own needs, thereby increasing the flexibility of the test.

[0088] In the embodiment of the present specification, the test PC sends instructions to control the first control unit or the second control unit through RS232 or LAN communication mode, so as to achieve the purpose of switching the required line, and solve the problem of cable bending and reduced standing wave ratio caused by manual replacement of RF cables, band-stop filters, and attenuators in the same test scenario affecting the test accuracy.

The first attenuator 320 may be a 10 dB attenuator, and the second attenuator 330 may be a 20 dB attenuator. The second control unit 420 includes a fifth digital switch 425, a sixth digital switch 426, a seventh digital switch 427, an eighth digital switch 428, a ninth digital switch 429 and a tenth digital switch 4210.

[0092] In the embodiment of the present specification, one end of the eighth digital switch 428 is connected to the fifth coupler 205, and the fifth coupler couples to receive the signal input from the second port 112 of the dual-channel signal source and the first single-channel signal source port 120, which can be used to test the blocking of the base station. Specifically, the second port 112 of the dual-channel signal source and the first single-channel signal source port 120 generate signals, and the two signal sources are respectively connected to the second port 112 of the dual-channel signal source and the first single-channel signal source port 120 through the radio frequency cable, and the thirteenth digital switch 4213 is switched to contact 3, and the two signals are coupled into one through the fifth coupler 205, and then the eighth digital switch 428 is switched to contact 6, the seventh digital switch 427 is switched to contact 2, and the sixth digital switch 426 is switched to contact 2, so as to realize the connection between the sixth digital switch and the seventh digital switch; further, the fifth digital switch 425 is switched to contact 2, and the fourth digital switch 424 is switched to contact 1, and finally the radio frequency signal is input to the radio frequency interface of the base station through the first input port 510 for testing.

[0097] Figure 3 The above is a schematic diagram of testing base station blocking according to an embodiment of this specification.

[0098] In this specification, the test of base station blocking is mainly carried out by coupling two RF signals into one through a coupler and then inputting the signals into the RF interface of the base station. Specifically, the test circuit inside the universal network equipment RF test system is as follows: Figure 3 As shown: two signal sources are connected to the first port of the dual-channel signal source of the general network equipment RF test system and one of the single-channel signal source ports (for example, the first single-channel signal source port 120) through RF cables respectively, the thirteenth digital switch 413 is switched to contact 3, the two signals are coupled to one signal through the fifth coupler 205, and then the eighth digital switch 428 is switched to contact 6, the seventh digital switch 427 is switched to contact 2, the sixth digital switch 426 is switched to contact 2, the fifth digital switch 425 is switched to contact 2, the fourth digital switch 424 is switched to contact 1, and the first digital switch 421 is switched to contact 1, and finally the RF signal emitted from the signal source is input to the RF interface of the base station through the first input port for testing.

[0099] Figure 4 The figure shows a schematic diagram of testing the blocking of a repeater according to an embodiment of the present specification. This figure can be used to test the blocking of a repeater.

[0100] In the embodiment of this specification, the system further comprises: a spectrum analyzer port and a repeater interface, the repeater interface is connected to a repeater under test outside the system, and the output end of the repeater under test is connected to the spectrum analyzer port in the system.

[0102] according to Figure 3 and Figure 4 From the structural diagram, it can be seen that for blocking tests on base stations and repeaters, it is necessary to couple the two RF signals through a coupler and input them into the RF interfaces of the two types of equipment. Therefore, the blocking of base stations and repeaters can be fully reused through the links at the through end and the coupled end of the coupler for testing, which not only achieves the effect of multiplexing links without adding RF devices and RF cables, but also meets the link budget.
