Product Description:
Advantest R3131A 3 GHz Spectrum Analyzer
The Advantest R3131A 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 R3131A. The CRT displays received signal strength (y-axis) against frequency ( x-axis).
Some applications for Advantest R3131A 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 R3131A 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 R3131A spectrum analyzer features include antenna isolation, co-channel interference, adjacent channel power, occupied bandwidth, intermodulation, microwave or satellite antenna alignment, and characterization of components.
Advantest has developed the R3131A 3GHz low-price spectrum analyzer, and put it on the market.The R3131A realizing a low price 15% lower than theprice of the conventional model from Advantest, allows integration of high-frequency devices/modules to the production line and remarkable cost reduction in the spectrum monitor market. In addition, it cultivates a new market of personal spectrum analyzers which are used by engineers for experiment. The R3131 is provided with the GPIB and RS-232C interface for use requiring connection with a personal computer.The waveform data can be printed directly to an external printer and stored in MS-DOS format floppy disks.In measurement, the analyzer displays the frequency counter and power measurement result with legible enlarged characters. Because of the standard automatic setting, Pass/Fail test, and setting condition memory functions
