MIL-STD-461 CS114

CS114 is a conducted susceptibility test specified by MIL-STD-461 that evaluates how well electronic equipment can withstand radio-frequency (RF) currents on its interconnecting cables. Covering a typical frequency range from 10 kHz to 200 MHz, it uses Bulk Current Injection (BCI) to apply controlled RF signals to cables connected to the Equipment Under Test (EUT). These signals simulate the real-world electromagnetic environment where multiple systems can operate side-by-side. During testing, the amplitude of the injected current is incrementally increased or swept through the range until it reaches the test limit. Throughout this procedure, the EUT’s performance is monitored to detect any signs of malfunction, data corruption, or undue signal distortion. By ensuring minimal impact on critical operations, CS114 helps validate the EUT’s reliability and robustness.

The test configuration generally includes a signal generator, power amplifier, directional coupler, and current probe, all connected through an automated or manual control system. Test levels and modulation (e.g., AM, FM, or pulse modulation) are prescribed by MIL-STD-461, corresponding to different operational requirements. The EUT must either continue functioning normally or experience only minor, acceptable degradation within the standard’s specifications. As such, meeting the CS114 requirements is especially critical for mission-oriented and safety-related applications—such as defense, aerospace, and other high-reliability environments—where unimpeded system operation under electromagnetic stress is paramount.
