That is, when the object to be tested includes the first branch to be tested, the second branch to be tested, the third branch to be tested, and the fourth branch to be tested, the signal input end is the input end of the four-power divider 3, the signal source 1 is connected to the input end of the four-power divider 3, and the spectrum analyzer 2 is connected to the output end of the device connected to the antenna input end in the branch to be tested. That is, during the test, the antenna in the target branch to be tested can be disconnected, and the output end of the device connected to the antenna input end can be connected to the spectrum analyzer to obtain the antenna reception signal. For example, it is connected to the output end of the first directional coupler 14 or the output end of the second adjustable attenuator 15 in the first branch to be tested.

[0093] Wherein, when the object to be tested includes four test branches, the spectrum analyzer 2 can be connected to the signal output ends of the four branches respectively, the signal source 1 inputs the signal to the four-power splitter 3, and the spectrum analyzer tests the spectrum power of the output signals of the four branches, and the signal quality of the downlink of the four branches can be analyzed. For example, when testing the first branch in the first branch to be tested, the signal source 1 sends an input signal to the four-power splitter 3, and the signal passes through the four-power splitter 3, the first adjustable attenuator 11, the trunk amplifier 12, the first two-power splitter 13, and the first directional coupler 14 in sequence and is output to the spectrum analyzer 2. The spectrum analyzer 2 outputs the spectrum power of the output signal of the first branch to be tested, and the signal quality of the downlink of the first branch to be tested can be analyzed.

[0094] Optionally, the signal source 1 and the spectrum analyzer 2 are also used to test the uplink of the branch to be tested.

[0095] The indoor distribution device also includes a transmitting antenna. During the test of the uplink of the object to be tested, the output end of the signal source 1 can be connected to the input end of the transmitting antenna. The transmitting antenna is used to transmit a signal to the antenna in the branch to be tested. At this time, the antenna inputs a signal to the branch to be tested. The spectrum analyzer 2 is connected to the output end of the branch to be tested (the input end of the original branch). That is, the input end and the output end of the object to be tested in the embodiment of the present disclosure are not designated fixed ports, and will change with the signal flow direction.

[0096] The transmitting antenna may be any type of antenna, which is not limited in this embodiment. Indicatively, the transmitting antenna may be an omnidirectional whip antenna. When testing the uplink of the branch to be tested, a signal source may be connected to the port of the omnidirectional whip antenna, and the omnidirectional whip antenna may be placed near the antenna in the branch to be tested, and a preset power may be transmitted through the omnidirectional whip antenna.

[0097] Optionally, when the object to be tested is the first branch to be tested, the transmitting antenna is communicatively connected to the first antenna 16 or the second antenna 17, and the output end of the signal source 1 is connected to the transmitting antenna (that is, the signal source 1 is indirectly connected to the input end of the first branch to be tested through the transmitting antenna, and the input end of the first branch to be tested is the antenna in the branch), and the input end of the spectrum analyzer 2 is connected to the output end of the first adjustable attenuator 11. At this time, the output end of the first adjustable attenuator 11 is the input end of the first adjustable attenuator 11 during the downlink test process, the signal source 1 sends an input signal to the transmitting antenna, and the transmitting antenna transmits the input signal to the first antenna 16 or the second antenna 17.

[0098] The first branch in the first branch to be tested can be tested, the transmitting antenna transmits a signal of preset power to the first antenna 16, and then the spectrum analyzer 2 is connected to the output end of the first adjustable attenuator 11. At this time, the input signal passes through the first antenna 16, the first directional coupler 14, the first two-power divider 13, the trunk amplifier 12 and the first adjustable attenuator 11 in sequence, and the first adjustable attenuator 11 outputs a signal to the spectrum analyzer 2. The spectrum analyzer 2 can test the spectrum power of the first branch in the first branch to be tested, thereby realizing the test of the uplink of the first branch.

[0099] Alternatively, the second branch in the first branch to be tested can be tested, the transmitting antenna transmits a signal of preset power to the second antenna 17, and then the spectrum analyzer 2 is connected to the output end of the first adjustable attenuator 11. At this time, the input signal passes through the second antenna 17, the second adjustable attenuator 15, the first power divider 13, the trunk amplifier 12 and the first adjustable attenuator 11, and the first adjustable attenuator 11 outputs a signal to the spectrum analyzer 2. The spectrum analyzer 2 can test the spectrum power of the second branch in the first branch to be tested, thereby realizing the test of the uplink of the second branch.

[0100] Optionally, when testing the uplink of the second branch to be tested, the transmitting antenna is communicatively connected to the third antenna 22, the output end of the signal source 1 is connected to the transmitting antenna, and the input end of the spectrum analyzer 2 is connected to the output end of the second directional coupler 21. At this time, the input signal is input to the second directional coupler 21 through the third antenna 22, and the output end of the second directional coupler 21 (the input end of the second directional coupler during the downlink test) outputs a signal to the spectrum analyzer.

[0101] Optionally, when testing the uplink of the third branch to be tested, the transmitting antenna is communicatively connected to the fourth antenna 33, the output end of the signal source 1 is connected to the transmitting antenna, and the spectrum analyzer 2 is connected to the output end of the second power divider 31 (the input end of the second power divider 31 during the downlink test). At this time, the input signal is output to the spectrum analyzer 2 through the fourth antenna 33, the third adjustable attenuator 32, and the second power divider 31, thereby realizing the test of the uplink of the third branch to be tested.

[0102] In another possible implementation, when the object to be tested includes a first branch to be tested, a second branch to be tested, a third branch to be tested and a fourth branch to be tested, when an uplink test is performed on the object to be tested, the output end of the signal source 1 is connected to the transmitting antenna, the transmitting antenna is communicatively connected to the antennas in the first branch to be tested, the second branch to be tested, the third branch to be tested and the fourth branch to be tested, and the spectrum analyzer 2 is connected to the output end of the four-power divider 3 (the input end of the four-power divider 3 during the downlink test).

[0103] Among them, a signal of preset power can be sent to the antennas in the first branch to be tested, the second branch to be tested, the third branch to be tested and the fourth branch to be tested respectively through the transmitting antenna, and the spectrum analyzer 2 respectively tests the spectrum power of the output signal (output through the four-power divider 3) of the first branch to be tested, the second branch to be tested, the third branch to be tested and the fourth branch to be tested, so as to obtain the signal quality of the uplink of the first branch to be tested, the second branch to be tested, the third branch to be tested and the fourth branch to be tested respectively. In the process of testing the second branch to be tested, the input signal is input into the second directional coupler 21 through the third antenna 22, and then input into the four-power divider 3, and the spectrum analyzer 2 is connected to the output end of the four-power divider 3 at this time.

[0104] Furthermore, the signal source 1 and the spectrum analyzer 2 can also be used to test device parameters of target devices in the first branch to be tested, the second branch to be tested, the third branch to be tested and the fourth branch to be tested, that is, the objects to be tested are target devices.

[0105] When testing a target device, the output end of the signal source 1 may be connected to the input end of the target device; and the input end of the spectrum analyzer 2 may be connected to the output end of the target test device.

[0106] Optionally, the signal source 1 and the spectrum analyzer 2 are used to test the loss value of the power divider, the coupling value of the directional coupler, the power value of the adjustable attenuator and the gain factor of the trunk amplifier.

[0107] In an illustrative embodiment, the signal source 1 and the spectrum analyzer 2 are used to test the loss value of the four-power divider. The output end of the signal source 1 can be connected to the input end of the four-power divider 3, and any output end of the four-power divider 3 can be disconnected and connected to the input end of the spectrum analyzer 2. A signal with a preset power can be sent to the four-power divider through the signal source 1, and the spectrum analyzer 2 can measure the power of the output signal of the four-power divider 3. According to the preset power and the measured power, the loss value of the four-power divider 3 can be obtained.

[0108] In an illustrative embodiment, the signal source 1 and the spectrum analyzer 2 are used to test the loss value of the two-power splitter. The output end of the signal source 1 can be connected to the input end of the two-power splitter, and any output end of the two-power splitter can be disconnected and connected to the input end of the spectrum analyzer 2. A signal of preset power can be sent to the two-power splitter through the signal source 1, and the spectrum analyzer 2 can measure the power of the output signal of the two-power splitter. According to the preset power and the measured power, the loss value of the two-power splitter can be obtained.

[0109] In another illustrative embodiment, the signal source 1 and the spectrum analyzer 2 are used to measure the coupling value of the second directional coupler 21. The output end of the signal source 1 can be connected to the input end of the second directional coupler 21, and the input end of the spectrum analyzer 2 can be connected to the output end of the second directional coupler 21. The coupling value of the second directional coupler 21 can be determined based on the preset power sent by the signal source 1 and the actual power measured by the spectrum analyzer 2.

[0110] In another exemplary embodiment, the signal source 1 and the spectrum analyzer 2 are used to test the third adjustable attenuator 32. The input end of the third adjustable attenuator 32 can be disconnected from the dimmer and connected to the output end of the signal source 1, and the output end of the third adjustable attenuator 32 can be disconnected from the fourth antenna 33 and connected to the input end of the spectrum analyzer 2. The signal source 1 sends a signal of preset power to the third adjustable attenuator 32, and the spectrum analyzer 2 can measure the power value of the output signal.

[0111] In another exemplary embodiment, the signal source 1 and the spectrum analyzer 2 are used to test the trunk amplifier 12. The input end of the trunk amplifier 12 can be disconnected from the output end of the first adjustable attenuator 11 and connected to the output end of the signal source 1, and the output end of the trunk amplifier 12 can be disconnected from the input end of the first dimmer 13 and connected to the input end of the spectrum analyzer 2. According to the preset power of the signal sent by the signal source 1 and the actual power measured by the spectrum analyzer 2, the amplification factor of the trunk amplifier can be calculated.

[0112] It should be noted that during the test process, the signal source can emit a preset signal that meets the test requirements according to the test requirements, such as a signal in the 5G frequency band.

[0113] In the disclosed embodiment, the ports of any device in the indoor distribution device with test function are independent and can be disconnected and connected arbitrarily. The signal source and spectrum analyzer can be connected to any port to test different branches or different devices. The test parameters of each part can be used in the design and maintenance process of the indoor distribution system, providing reliable experimental parameters for the design and maintenance of the indoor distribution system. The system includes a variety of discrete devices to test different devices to determine the performance of different devices and provide guidance for using them in indoor distribution systems.

[0114] In order to more easily connect the input and output ports of the port device, the input and output ends of at least one device in the indoor distribution device are respectively provided with a bayonet nut connector (British Naval Connector, BNC). In a possible implementation, BNC can be provided at the input and output ends of all devices. That is, in the embodiment of the present disclosure, the input and output ends of the device are uniformly converted to BNC type ports for connection.

[0115] That is, any device in the first branch to be tested, the second branch to be tested, the third branch to be tested and the fourth branch to be tested and the input end and the output end of the four-power divider 3 are connected to other devices through the BNC port.

[0116] Most of the ports of the device are N-type ports. Since N-type ports are not easy to operate, in order to more conveniently connect the ports, the N-type ports are uniformly converted to BNC-type ports for connection. Figure 3 As shown, for an N-type port of a device, it is first converted to a BNC-type port through an N-to-BNC connector, and then the BNC port is connected to the BNC-to-N connector, and the BNC-to-N connector is then connected to the N-type port of another device to be connected. The converted BNC port is connected to the BNC-to-N connector through the opening of the BNC, and the BNC-to-N connector is then connected to the N-type connector through a feeder.

[0117] In combination with the above example, when the output end of the four-power divider 3 and the input port of the first adjustable attenuator 11 are both N-type ports and the two need to be connected, the output end of the four-power divider 3 can be connected to the N-to-BNC connector, and then the N-to-BNC connector is connected to the BNC-to-N connector through the BNC bayonet, and the input N-type port of the first adjustable attenuator 11 is connected to the BNC-to-N connector through a feeder, so as to realize the connection between the output end of the four-power divider 3 and the input end of the first adjustable attenuator 11.

[0120] In a possible implementation manner, the first antenna 17 , the second antenna 18 , the third antenna 23 , the fourth antenna 33 , and the fifth antenna 42 may be antennas of different types.

[0121] In another possible implementation, at least two antennas of the same type may exist among the first antenna 17 , the second antenna 18 , the third antenna 23 , the fourth antenna 33 , and the fifth antenna 42 , so as to be used for comparison of different branches.

[0122] Illustratively, the first antenna 17 and the third antenna 23 may be indoor mushroom-shaped antennas; the second antenna 18 and the fourth antenna 33 may be log-periodic antennas; and the fifth antenna 42 may be a plate-shaped antenna.
