Automatic test systems often employ a class of instruments (switch matrix, controllers, etc.) to effect the exchange of signals between the system and the unit under test and to provide the necessary signals and loads to the unit under test. This type of instrument features multiple ports (panel adapters) on the panel for signal exchange. The panel adapter of the instrument is required to be attractive and elegant in layout, and is generally arranged according to a rectangular array, the row or column spacing is equal, and the spacing is proper; the inside of the switch realizes signal exchange through a microwave switch (hereinafter referred to as a switch for short), the switch is provided with a plurality of ports with the same function, and the ports are usually arranged in a circular array; the panel adapter is connected to the switch and the switch by a semi-rigid coaxial cable (hereinafter referred to as a semi-rigid cable).

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

The invention provides a layout method of a switch and panel adapter, which takes a single-pole multi-throw switch as an example, and comprises the following specific embodiments:

as shown in fig. 1, a layout method of a switch and panel adapter, the switch and the instrument panel are installed in the same direction; n ports of the switch 1 are uniformly arranged on a circle with radius r, corresponding n panel adapters 2 are arranged in a matrix with a columns and b rows, n is a multiplied by b, the row spacing of the panel adapters 2 is h, the column spacing is w, and the lengths of projection lines of connecting lines between the switch ports 3 and the corresponding panel adapter ports 4 in the direction of the instrument panel are equal to each other and are all L.

As shown in fig. 2, taking a single-pole 6-throw switch as an example (n ═ 6), the switch can be rotated by 90 ° for use:

solving the following equation:

when the 6 throw switches of multiunit single-pole are used jointly, make the vertical direction interval of switch be H, the horizontal direction interval is W, still will satisfy panel adapter evenly distributed's requirement, need satisfy promptly:

W＝2w；

H＝3h。

the equation set has no array solution, and in practical application, values of other parameters can be obtained by setting a certain unknown value according to the combination of limiting conditions (such as switch spacing W, H > the size of a switch flange plate, the cable projection length L needs to meet the requirement of manufacturing the semi-rigid cable 5, and the panel adapter spacing w and h need to facilitate the cable disassembly and assembly), so that the design of specific panel layout is completed.

There is another layout of the single-pole 6-throw switch, such as the connection shown in fig. 3, which also satisfies the above formula.

According to the solving method, the layout of other switches and panel adapters can be popularized, and fig. 4 and 5 show two layout methods of single-pole 8-throw switches and panel adapters, which can be rotated by 90 degrees for use.

The layout method shown in fig. 4 has the following relationship:

the layout method shown in fig. 5 has the following relationship:

when the 8 throw switches of multiunit single-pole were used jointly, it was H to make the vertical direction interval of switch, and the horizontal direction interval is W, still will satisfy panel adapter evenly distributed's requirement, need satisfy promptly:

W＝4w；

H＝2h。

the layout methods of the switches and panel adapters of the other specifications can be derived and solved according to the above method, and are not described again.

When the method is used for designing the instrument, the same switch can be arranged according to the layout method, the distances among the ports of the panel are the same, and the projection lengths of the semi-rigid cables in the panel direction are the same (the same as the installation positions of the instrument switch in the depth direction of the instrument, so that the types of the cables are reduced into one type). Among different instruments, as long as the same mounting position of the switch in the depth direction of the instrument is ensured, the same type of switch can be connected with the panel adapter in different instruments by using the same type of semi-rigid cable, and the universality is improved.

After the types of cables between the switch and the panel adapter are reduced to one type, the consistency of all ports of the instrument can be ensured as long as the electrical length of the semi-rigid cable between the switch and the switch is ensured to be consistent, and the design difficulty of the consistency is reduced.

In the case where the cables cross in the projection view, the same type of semi-rigid cable 5 may be changed in the installation direction so as to be spatially staggered to avoid interference, as shown in fig. 6.
