Description

Agilent E4408B ESA-L Spectrum Analyzer is a professional RF and microwave spectrum analyzer covering a frequency range of 9 kHz to 26.5 GHz. It is designed for general-purpose spectrum analysis, RF measurements, manufacturing test, service, research, and laboratory applications. The E4408B belongs to Agilent's ESA-L series and is the 26.5 GHz model in the series. It is now a discontinued/obsolete instrument, with the Keysight N9000B CXA listed as a replacement. The analyzer provides a wide range of frequency-domain measurements, including carrier and harmonic measurements, spurious emissions, occupied bandwidth, channel power, adjacent-channel measurements, noise measurements, and general RF signal characterization. Optional configurations could add features such as a 50 Ω tracking generator, narrow resolution bandwidths, and additional measurement capabilities.
