Advantest R3131

3 GHz Spectrum Analyzer, Type N (f)

Product Overview

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.
