Agilent Technologies 8595E Portable Spectrum Analyzer, 9kHz to 6.5 GHz
The Agilent Technologies 8595E 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 8595E. The CRT displays received signal strength ( y-axis) against frequency ( x-axis) .
Some applications for Agilent Technologies 8595E 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 8595E 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 8595E spectrum analyzer features include antenna isolation, co-channel interference, adjacent channel power, occupied bandwidth, intermodulation, microwave or satellite antenna alignment, and characterization of components.
