In EMI Resolution, which is the first phase?

• A. Monitoring
• B. Detection
• C. Characterization
• D. Identification

Answer: (A)

Starting with continuous observation of the electromagnetic environment and system performance is essential because it establishes what normal looks like and provides the data needed to spot deviations. This ongoing monitoring sets up baselines, health of sensors, and real-time visibility, so when anything unusual occurs you have immediate evidence to act on. That’s why it’s the first phase in EMI Resolution—without monitoring, you wouldn’t know when an interference event happens or have the data to analyze it later. Once monitoring is in place, you move to detect anomalies, characterize their properties (such as frequency, duration, and waveform), and ultimately identify the source. Monitoring underpins all the subsequent steps, enabling reliable alerts, informed analysis, and accurate attribution.
