Product Description:
Advantest R3131 3 GHz Spectrum Analyzer
The Advantest R3131 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 Advantest R3131. The CRT displays received signal strength (y-axis) against frequency ( x-axis).
Some applications for Advantest R3131 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 Advantest R3131 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 Advantest R3131 spectrum analyzer features include antenna isolation, co-channel interference, adjacent channel power, occupied bandwidth, intermodulation, microwave or satellite antenna alignment, and characterization of components.
The R3131 is an easy-to-use personal spectrum analyzer which combines high accuracy necessary for digital radio measurement with excellent operability and usability. The R3131 can be used in diverse fields, for a multitude of applications.
