The Advantest R3271 has excellent spectral purity, a resolution bandwidth of 10 Hz to 3 MHz, the ability to sweep the complete frequency range continuously and repeatedly and a built-int frequency range counter are just a few features that make this an exceptional value. The R3271 is designed to analyze pulse RF signals used for radar or to analyze the spectrums of microwaves and quasi-millimetric waves used for satellite broadcasting, satellite communications, or mobile communication. The Advantest R3271 can measure the ultra-broad bandwidth of 100 Hz to 26.5 GHz in one sweep operation. It can also perform the sweep continuously and repeatedly. The R3271 spectrum analyzer is thus ideally suited for mobile radiocommunication, for which narrower bandwidths and digitalization are being advanced.
