Description

Technical Field

[0001] The utility model relates to the technical field of network analysis equipment, and particularly relates to a 40GHz extended PXIE vector network analysis structure. Background Art

[0002] A network analyzer is a comprehensive microwave measuring instrument that can perform scanning measurements within a wide frequency band to determine network parameters. It is widely used in multiple fields such as communication and electronic engineering, and particularly plays an important role in precise guidance, stealth and anti-stealth, aerospace, satellite communication, radar detection and surveillance, etc.

[0003] As Figure 1 shown, the existing network analyzer usually only has a basic module 1. On one side of the basic module 1, there is an interface panel 2, and an output interface 3 is provided on the interface panel 2. The basic module 1 has a measurement operating frequency of 20GHz. According to the requirements in the actual use process, the measurement operating frequency of 20GHz is sometimes insufficient to meet the use requirements. If the external expansion module 4 is directly connected through the output interface 3, the overall stability is poor and the signal transmission is unstable. Summary of the Utility Model

Its function is that through the setting of the bolt seats and the connection screws, the expansion module (the loading board, the protective shell, and each module between the loading board and the protective shell) can be stably connected to the basic module, which is convenient to carry and ensures the stability of signal transmission.

[0007] Further, an input interface connected to the expansion module is provided on the section of the interface panel corresponding to the expansion module, and the input interface and the output interface are connected by a semi-rigid cable.

[0013] Further, a winding post is provided between the interface slot and the cable slot. Its function is that through the setting of the winding post, the semi-rigid cable connected to the source interface can bypass the winding post and be connected to the second input interface.

[0031] The 40GHz extended PXIE vector network analysis structure, as Figure 5 shown, includes a basic module 1. An interface panel 2 is provided on one side of the basic module 1, and an output interface 3 is provided on the interface panel 2. An extended module 4 is provided on the basic module 1. The extended module 4 includes a loading board 41 and a protective shell 42. A receiving module 43 and a source module 44 which are connected to each other are provided between the loading board 41 and the protective shell 42.

It also includes a connecting bolt 6 that penetrates the loading board 41, presses on the top surface of the protective shell 42 and is threadedly connected to the bolt seat 5. A plurality of pins for inserting into the loading board 41 are provided on the bottom surface of the receiving module 43. The receiving module 43 and the source module 44 themselves adopt the prior art and will not be elaborated. The receiving module 43 and the source module 44 are directly connected through a connection joint, and the connection joint adopts the prior art. Its function is that through the setting of the bolt seat 5 and the connecting screw, the extended module 4 (the loading board 41, the protective shell 42 and each module between the loading board 41 and the protective shell 42) can be stably connected to the basic module 1, which is convenient to carry and ensures the stability of signal transmission.

[0032] Specifically, as Figure 3As shown, on the section of the interface panel 2 corresponding to the expansion module 4, there is an input interface 8 connected to the expansion module 4. The input interface 8 and the output interface 3 are connected by a semi-rigid cable 7. The semi-rigid cable 7 itself uses existing technology and will not be elaborated. Its function is that through the setting of the input interface 8, the basic module 1 and the expansion module 4 can complete information transmission.

[0033] Specifically, as Figure 3 shown, the input interface 8 includes a first input interface 81 connected to the receiving module 43 and a second input interface 82 connected to the source module 44.

[0034] Specifically, as Figure 4 shown, the receiving module 43 is provided between the source module 44 and the interface panel 2. There is a source interface 9 on the source module 44. The source interface 9 and the second input interface 82 are connected by a semi-rigid cable 7.

[0035] Specifically, as Figure 5 shown, there are two source modules 44. The semi-rigid cables 7 connected to the two source modules 44 are located on the left and right sides of the receiving module 43. Each semi-rigid cable 7 connected to a source module 44 is respectively connected to a second input interface 82.

[0036] Specifically, as Figure 4 shown, on the left and right sides of the receiving module 43 near the interface panel 2, there are wing plates 10. There are placement grooves 11 with openings downward on the wing plates 10. There is a support section 12 on the second input interface 82. The outer diameter of the support section 12 is equal to the width of the placement groove 11. The distance between the two support sections 12 is equal to the distance between the two placement grooves 11. Its function is that through the design of the placement grooves 11 on the wing plates 10 and the support sections 12 on the second input interface 82, the two placement grooves 11 can be stably placed on the support sections 12, preventing the receiving module 43 from shaking in the left and right directions.

[0037] Specifically, as Figure 5 shown, the source interface 9 is provided on the side of the source module 44 facing away from the interface panel 2. There is an interface slot 13 for the source interface 9 to pass through and a cable slot 14 for the semi-rigid cable 7 to pass through on the protective shell 42. Its function is that through the setting of the position of the source interface 9, the semi-rigid cable 7 can be directly inserted from the side of the expansion module 4 facing away from the interface panel 2. At the same time, the source interface 9 and the input interface 8 are respectively located on opposite sides of the interface panel 2, facilitating the insertion of the semi-rigid cable 7 into the input interface 8 or the source interface 9, and the installation is convenient.

[0038] Specifically, as Figure 2As shown, a wire winding post 15 is provided between the interface slot 13 and the cable slot 14. Its function is that through the setting of the wire winding post 15, the semi-rigid cable 7 connected to the source interface 9 can bypass the wire winding post 15 and be connected to the second input interface 82.

[0039] Specifically, as Figure 5 shown, a transmission channel 16 penetrating through the interface panel 2 is provided on the receiving module 43.

[0040] Specifically, as Figure 4 shown, a limiting strip 17 is provided on the side of the interface panel 2 facing the expansion module 4 and is directly above the protective shell 42. A shielding strip 18 is provided on the limiting strip 17. Its function is that through the setting of the limiting strip 17, the tendency of the protective shell 42 to move upward can be further restricted.

[0041] The working principle of this embodiment is described as follows: First, place the loading plate 41 on the bolt seat 5, and then hang the receiving module 43 connected to the active module 44 on the support section 12, so that the first input interface 81 and the transmission channel 16 pass through the interface panel 2. Since the second input interface 82 is fixedly connected to the interface panel 2, the support sections 12 of the left and right second input interfaces 82 can limit the movement of the receiving module 43 in the left and right directions. Then, insert the protective shell 42 between the limiting strip 17 and the receiving module 43, so that the source interface 9 is located in the interface slot 13, and the semi-rigid cable 7 on the source interface 9 passes through the wire winding post 15 and is located in the cable slot 14 and is connected to the second input interface 82.

[0042] The above is only a preferred embodiment of the present invention, and it does not impose any form of limitation on the present invention. Based on the technical essence of the present invention, within the spirit and principle of the present invention, any simple modification, equivalent replacement, and improvement made to the above embodiments still fall within the protection scope of the technical solution of the present invention.
