Product Description:
Advantest R4131D 10 kHz to 3.5GHz,Spectrum Analyzer
The Advantest R4131D 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 R4131D. The CRT displays received signal strength (y-axis) against frequency ( x-axis).
Some applications for Advantest R4131D 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 R4131D 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 R4131D spectrum analyzer features include antenna isolation, co-channel interference, adjacent channel power, occupied bandwidth, intermodulation, microwave or satellite antenna alignment, and characterization of components.
Feature:Minimum Frequency: 10kHz
Maximum Frequency: 3.5GHz
Resolution bandwidth: 1kHz
Spectrum Analyzers
R4131 Series are lightweight and compact spectrum analyzers which can cover a wide bandwidth of 10 kHz to 3.5 GHz in a single sweep.
The R4131 series features a maximum input sensitivity of û116 dBm, a dynamic range of 70 dB and a noise sidebands of û80 dBc or better.
Especially, the D type analyzer provides AFC (Automatic Frequency Control), enabling highly stable spectrum analysis. The ease of use has been improved through the MemoryFunction which stores measurement conditions such as wave-form and the Auto Recall Function which recalls measurement conditions when the power is turned on. In addition to these new features, these analyzers use the proven spectrum analysis, with standard features of field strength measurements compensated for antenna calibration factor and quasipeak value measurements conforming to CISPR standards.
For systemization, a GPIB interface is provided as standard and there is wide variety of direct plotting and video signal Auto-Recall Function
