Agilent / HP / Keysight E4448A
E4448A PSA Spectrum Analyzer, 3 Hz to 50 GHz
Description
The E4448A Spectrum Analyzer is one of our PSA series of modern, high-performance spectrum analyzers now offering comprehensive one-button power measurements and measurement personalities with digital demodulation for 2G/3G applications.
The PSA series combines these personalities with strong measurement performance to meet both general-purpose and highly specialized signal analysis needs in aerospace/defense, wireless communications and other industries.
The PSA series offers an entirely new platform for spectrum analysis that provides the most advanced overall performance and dramatic improvements in accuracy, dynamic range, sensitivity, resolution and speed.
The E4448A is the 3Hz to 50 GHz model in the PSA series. It offers high performance spectrum analysis at an excellent price. The Agilent E4448A PSA gives unparalleled levels of measurement capability up to 50 GHz.
