Description

Technical Field

[0001] The utility model relates to a novel electric field probe mounting bracket for electromagnetic compatibility uniform domain calibration, belonging to the technical field of electromagnetic compatibility testing. Background Art

[0002] Since most electrical and electronic equipment are affected by electromagnetic radiation under certain circumstances, and the use of wireless phones and other radio frequency transmitting devices has increased significantly in recent years, almost every electrical and electronic equipment needs to undergo radio frequency electromagnetic field radiation immunity tests to prevent interference from external radiation during normal operation. This test requires field calibration, i.e. uniform domain calibration, before the test. Its purpose is to ensure the uniformity of the electromagnetic field around the tested product to ensure the validity of the test results. During the uniform domain calibration process, the forward power of the test system needs to be adjusted at each specific frequency through the monitoring value of the field strength probe, and the 16 points specified in the standard are calibrated in turn. Since the horizontal and vertical positions of these 16 points are specified in the standard, all the position measurements need to be performed when calibrating each point before the probe can be placed at the measurement point for field monitoring. This not only wastes time, but also is very troublesome to move the field probe each time.

[0003] In order to solve the above problems, a new type of electric field probe mounting bracket is provided, which can not only connect and quickly locate the measurement point, but also ensure the accuracy of the measurement, which provides great convenience for conducting radio frequency electromagnetic field radiation immunity tests.
