Real-Time Spectrum Analyzers (RTSA) are advanced electronic test instruments designed for capturing and analyzing RF signals in real-time. They excel in detecting transient or intermittent signals, making them ideal for applications like wireless communications, radar systems, and spectrum monitoring. Key features include high-speed processing, wide bandwidth, and dynamic range, enabling precise signal characterization in industrial, military, and research environments. RTSAs are critical for troubleshooting, compliance testing, and signal intelligence in fast-paced, high-frequency scenarios.
