## Abstract

A method and apparatus for configuring a conductive plane for electromagnetic compatibility test of equipment or device. A positioning object is fixed above the plane of a conductive plane, the positioning object contacts an equipment under test (EUT), and the distance from the EUT to the conductive plane is equal to the distance from the positioning object to the conductive plane plus the thickness of the positioning object, thereby avoiding an error in measurement caused by a change in the distance from the conductive plane to the EUT during each test. In addition, the device is portable, and the conductive plane does not need to be grounded, and may be applied to a production site or field in which no grounding is available.

## Claims

### Claim 1

A method of setting a conductive plane, the method comprises: integrating the conductive plane for electromagnetic interference measurement with a box; said integration comprising fixing the conductive plane to the surface of the box and fixing the conductive plane to the interior of the box; said box as a container has interior space and is freely movable without tied/fixed to any object.

### Claim 2 (depends on 1)

The method according to claim 1, when testing electromagnetic interference, placing the box which the conductive plane is fixed on, in the vicinity of an object to be tested; said vicinity includes the front, rear, left, right, above and below the object to be tested.

### Claim 3 (depends on 1)

The method according to claim 1, wherein the box is a device or equipment for electromagnetic interference measurement.

### Claim 4 (depends on 1)

The method according to claim 1, wherein the box is portable.

### Claim 5

A conductive plane device, comprising:
a conductive plane for electromagnetic interference measurement, a box, the conductive plane being integrated with the box; said integration comprises fixing the conductive plane to the surface of the box and fixing the conductive plane inside the box; said box as a container has interior space and is freely movable without tied/fixed to any object.

### Claim 6 (depends on 5)

The device according to claim 5, wherein the conductive plane area is less than 2 m×2 m.
