Description: The Agilent 71209A 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 71209A. The CRT displays received signal strength (y-axis) against frequency ( x-axis).
Some applications for the Agilent 71209A 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 71209A 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.
