Advantest R3131

The Advantest R3131 Spectrum Analyzer meets the frequency needs of both PCS and cellular wireless standards. The Advantest R3131 is the only Refurbished 3GHz Spectrum Analyzer at its price that is synthesized. The synthesized architecture and specifications such as phase noise lower than -100 dBc/Hz @ 20kHz offset, ensure measurement accuracy and repeatability across the instrument's entire range. This level of accuracy, plus one-button automated measurements for adjacent channel power, occupied bandwidth, and average and total power, make the Advantest R3131 well-suited to wireless design and troubleshooting needs. Supplementing these quantitative measurements, the R3131 also provides automatic pass/fail limit testing, a valued feature for manufacturing applications.
