RF Analysis — Top 10 Current Applications

1. Interference detection and root-cause analysis
   One of the biggest and most immediate uses: finding what is polluting the band, where it is, and how severe it is.

2. Spectrum monitoring and occupancy analysis
   Determining who is using which frequencies, when, and how heavily.

3. Emitter detection, identification, and characterization
   Identifying unknown transmitters, classifying modulation/use, and estimating operational behavior.

4. Wireless network troubleshooting and performance analysis
   Wi-Fi, cellular, telemetry, and radio systems benefit heavily from RF diagnostics.

5. Radar signal analysis and evaluation
   Pulse analysis, radar coexistence, and radar performance assessment remain core RF tasks.

6. EMI/EMC pre-compliance and troubleshooting
   Very valuable in electronics and manufacturing when products fail emissions or susceptibility expectations.

7. Direction finding and geolocation support
   Locating the source of an emitter or interference event is a major operational use case.

8. RF component and antenna performance testing
   Analyzing filters, amplifiers, oscillators, mixers, antennas, and feed systems.

9. Brief-event and transient capture
   Real-time spectrum tools are especially useful when signals are intermittent, pulsed, or short-duration.

10. Security, surveillance, and unauthorized transmitter detection
    Finding rogue transmitters, hidden emitters, or suspicious RF activity is a live and useful niche.
