s guide (see Regulatory Position C.2). The test is applicable to equipment and subsystem enclosures and all interconnecting leads. The test is not applicable for electromagnetic coupling via antennas. The equipment under test should not exhibit any malfunction or degradation of performance beyond specified operational tolerances when subjected to the rms magnetic field levels shown in Figure 4.3. Acceptable performance should be defined in the test plan by the end user or testing organization according to the applicable equipment, subsystem, or system specifications. Figure 4.3 Low-Frequency Radiated Susceptibility Envelopes 4.3.2 RS103—Radiated Susceptibility, Electric Fields The RS103 test ensures that equipment and subsystems are not susceptible to radiated electric fields in the frequency range from 30 MHz to 10 GHz. The test is applicable to equipment and subsystem enclosures and all interconnecting leads. The test is not applicable at the tuned frequency of antenna- connected receivers unless otherwise specified. The equipment under test should not exhibit any malfunction or degradation of performance beyond specified operational tolerances when subjected to the radiated electric fields. The applied electric field level should be 10 V/m (rms), measured in accordance with the techniques specified in the RS103 test method. The test method should be performed for both horizontally and vertically polarized fields. As described in MIL-STD-461G, circularly polarized fields are not acceptable because radiated electric fields are typically linearly polarized. Acceptable performance should be defined in the test plan by the end user or testing organization according to the applicable equipment, subsystem, or system specifications. 4.3.3 IEC Radiated Susceptibility Tests DG-1333, Page 24 The IEC counterparts for the RS101 test are IEC 61000-4-8, IEC 61000-4-9, and IEC 61000-4-10. Operating envelopes corresponding to the Class 4 test level for each IEC test method are
