Agilent E4402B 9KHZ-3GHZ spectrum analyzer w/ opt A4H
Agilent E4402B 9kHz-3GHz Spectrum Analyzer w/ Option A4H **Tested**
The Agilent HP E4402B spectrum analyzer is a wide band, very sensitive receiver. It works on the principle of "super-heterodyne receiver" to convert higher frequencies (normally ranging up to several 10s of GHz) 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 (usually logarithmic scale), and displaying the same on the CRT of the Agilent Technologies Inc. E4402B. The CRT displays received signal strength (y-axis) against frequency ( x-axis).
Some applications for Agilent Technologies Inc. E4402B 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 Technologies Inc. E4402B spectrum analyzer to verify that the frequencies (you plan to use) are not occupied or if the presence of a very strong signal will interfere with your new setup. Interference can be created by a number of different situations. Other tests that utilize the Agilent Technologies Inc. E4402B spectrum analyzer features include antenna isolation, co-channel interference, adjacent channel power, occupied bandwidth, intermodulation, microwave or satellite antenna alignment, and characterization of components.
