e4407b esa-e 9khz-26.5 ghz spectrum analyzer
the agilent technologies inc. e4407b 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. e4407b. the crt displays received signal strength (y-axis) against frequency ( x-axis).
some applications for agilent technologies inc. e4407b 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. e4407b 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. e4407b spectrum analyzer features include antenna isolation, co-channel interference, adjacent channel power, occupied bandwidth, intermodulation, microwave or satellite antenna alignment, and characterization of components.
