The Advantest R3131 Spectrum Analyzer offers a 9kHz to 3GHz frequency range, meeting the frequency needs of both PCS and cellular wireless standards.
The R3131 synthesized architecture and specifications such as phase noise lower than -100 dBc/Hz @ 20kHz offset, ensure measurement accuracy and repeatability across the instruments entire range.

This level of accuracy, plus one-button automated measurements for adjacent channel power, occupied bandwidth, and average and total power, make the 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.
