A comparison of the isotropic broadband susceptibility test method and an RS103 test on an ARC-182 radio

Abstract

The isotropic broadband susceptibility (IBS) test method is a new radiated susceptibility method. This method uses band limited white Gaussian noise which is upconverted by performing double sideband, suppressed carrier modulation with an RF or microwave signal. This method is performed in a high Q chamber so that the test sample is uniformly radiated on all sides by the field as in a mode-stirred chamber. Testing was performed on an ARC-182 radio with the IBS method in order to determine if the IBS method could find susceptibilities on equipment with extremely narrow failure bandwidths. The results of the testing were compared with the results of an RS103 test performed in accordance with MIL-STD-462D on the same ARC-182 radio. Testing was performed as an investigation to evaluate the method as a possible alternate method to RS103.<>
