Embodiment Construction

[0016] see figure 1 , the uniform domain test device 100 of the preferred embodiment of the present invention includes a test frame 10 and several field strength probes 20 , and the field strength probes 20 are at least partly detachably installed on the test frame 10 . The test frame 10 includes a base 12 , two columns 14 and a plurality of cross bars 16 . The base 12 is a flat plate arranged horizontally. Two columns 14 stand vertically on the base 12 and are parallel to each other. On each column 14, a plurality of horizontal bars 16 parallel to each other are arranged horizontally at intervals. The plurality of crossbars 16 are respectively arranged at a plurality of predetermined heights on the two columns 14 , and the heights of the plurality of crossbars 16 on the two columns 14 are correspondingly equal. The end of each crossbar 16 on a column 14 is respectively aligned with the end of a corresponding crossbar 16 at the same height on the other column 14, so that ever...

Abstract

The invention provides a homogeneous domain testing device which is suitable for homogeneous domain testing of electromagnetic field radiation interference immunity. The homogeneous domain testing device comprises a testing frame and a plurality of field intensity probes mounted on the testing frame, wherein the field intensity probes are positioned in the same plane and distributed in an array manner, and a spacing of the same row or column of every two adjacent field intensity probes is not less than the minimum spacing of every two adjacent testing points in the homogeneous domain testing of the electromagnetic field radiation interference immunity. The invention further provides a method for conducting the homogeneous domain testing of the electromagnetic field radiation interference immunity by the homogeneous domain testing device.

Description

technical field [0001] The invention relates to the field of electromagnetic field testing, in particular to a uniform domain testing device and testing method for electromagnetic field radiation immunity. Background technique [0002] Before carrying out the radio frequency electromagnetic field radiation immunity test of the electromagnetic compatibility test, it is necessary to verify the test site and perform uniform domain measurement to ensure that the electromagnetic field strength distribution in the test site is sufficiently uniform. Generally speaking, the size of the homogeneous field used in the test is 1.5m×1.5m, which contains sixteen test points for the field strength measurement of the homogeneous field. When performing the measurement in the uniform domain, place the field strength probe on one of the test points, use the signal generator, power amplifier and transmitting antenna in each predetermined transmitting frequency segment with different antenna pol...
