Spectrum Analyzers : Agilent-HP E4411B-1DP-A4H

The Agilent E4411B spectrum analyzer is a wide band, sensitive receiver. It works on the principle of "super-heterodyne receiver" to convert higher frequencies to measurable quantities. The received frequency spectrum is slowly swept through a range of pre-selected frequencies, converting the selected frequency to a measurable DC level and displaying the same on the CRT of the Agilent E4411B. The CRT displays received signal strength (y-axis) against frequency ( x-axis).

Applications for Agilent E4411B Spectrum Analyzers include Site Monitoring: Verify that the frequency and signal strength of your transmitter is accurate. Interference: Before a system is installed you use a Agilent E4411B spectrum analyzer to verify that the frequencies are not occupied or if the presence of a very strong signal will interfere with your new setup. Other tests that utilize the Agilent E4411B spectrum analyzer features are antenna isolation, co-channel interference, adjacent channel power, occupied bandwidth, intermodulation, microwave or satellite antenna alignment, and characterization of components.
