Basic Spectrum Analyzers are essential industrial instruments used to measure and analyze the frequency spectrum of electrical signals. They are widely applied in telecommunications, RF testing, and electronic manufacturing for signal integrity verification, interference detection, and compliance testing. These devices typically feature real-time analysis, wide frequency ranges, and user-friendly interfaces, making them suitable for both field and lab environments. Common applications include troubleshooting wireless networks, optimizing broadcast systems, and ensuring electromagnetic compatibility (EMC) in industrial equipment.
