Agilent E4411B ESA-L Series Spectrum Analyzer 9kHz – 1.5gHz

Agilent E4411B ESA-L Series Spectrum Analyzer 9kHz – 1.5GHz,”This spectrum analyzer provides comprehensive signal analysis over a frequency range from 9 kHz to 1.5 GHz, making it ideal for RF circuit design, EMI pre-compliance testing, and general-purpose spectrum monitoring. It features a compact, bench-friendly design with a bright, high-resolution display for easy signal visualization. The analyzer supports marker functions, peak search, and automated measurements such as occupied bandwidth and channel power. With good sensitivity and dynamic range, it can resolve closely spaced signals and detect low-level interference. Built-in calibration ensures long-term measurement stability, and GPIB interface enables system integration for automated testing. The instrument’s fast sweep time and clear trace display make it easy to characterize RF behavior quickly. Common applications include RF transmitter testing, antenna pattern verification, and power spectrum analysis in wireless labs and repair centers. Its ease of use, reliability, and consistent performance make it a valuable tool for any RF lab environment requiring mid-frequency signal observation.”
