Description

Technical Field

[0001] The present application relates to the field of electromagnetic compatibility technology, and in particular to an RS103 high frequency testing device and a method for using the same. Background Art

[0002] The RS103 (10kHz~40GHz electric field radiation sensitivity) test is to test the ability of the equipment under test (EUT) and related cables to withstand the radiated electric field, ensuring that the equipment working in the electromagnetic field generated by various transmitting antennas on or outside the platform does not degrade its performance. RS103 is a project that all platform products should be evaluated. The test layout diagram is as follows Figure 1 The signal generator in the control room outputs the signal, which is amplified by the RF amplifier and then transmitted to the transmitting antenna, which irradiates the equipment under test (EUT). The level of the irradiated electric field strength meets the standard limit requirements, and both horizontal and vertical polarization fields should be irradiated.

[0003] Since the size of each EUT is different, the horn antenna often needs to be moved to multiple positions in the horizontal and vertical directions during the RS103 test to achieve the illumination of the entire EUT, and each position needs to complete the horizontal and vertical polarization field illumination. In addition, different EUTs require different illumination field strength amplitudes, so it is also necessary to adjust the distance between the horn antenna and the EUT.
