Specific Radiated Susceptibility Requirements Mil-Std 461E

RS101 - Magnetic Field (30 kHz to 100 kHz)

This is a specialized requirement and is intended primarily to ensure the performance of equipment potentially sensitive to low frequency magnetic fields. It is applicable to subsystems enclosures and electrical cable interfaces. Not applicable for electromagnetic coupling via antennas. This test is required for the following platforms:

Submarines
Army aircraft (Including Flight Line)
Navy aircraft - With Anti Submarine Warfare

RS103 - Electric Field (2 MHz to 40 GHz)

The basic concept is to insure the EUT will continue to operate as intended without degradation. In the presence of electromagnetic fields generated by antenna transmissions both on board and external to the tested platform. The EUT shall not exhibit any malfunction, degradation of performance, or deviation from the specified requirements. The requirements are applicable to equipment, subsystems enclosures, and all interconnecting cables. Most requirements are referenced up to 18 GHz, with an optional 40 GHz range. Field strength can vary depending on the specific requirements.

This is a widely devolved test and is required on the following platforms:

Additional Information About RS103

With the E version of Mil Std now applicable, some changes are noted here. Submarine applications are dependent on location of the device when installed, internal versus external to the pressure hull. Internal requirements have changes for field strength to 10 volts per meter for frequencies above 20 MHz. External hull field strength-testing requirements increased to 200 volts per meter for applications over the water line. Army aircraft field strength requirements increase to 200 volts per meter, regardless of location.
