The R3131A offers a 9 kHz to 3 GHz frequency range, meeting the frequency needs of both PCS and cellular wireless standards. The synthesized architecture and specifications such as phase noise lower than -100 dBc/Hz @ 20 kHz offset, ensure measurement accuracy and repeatability. This level of accuracy, plus one-button automated measurements for adjacent channel power, occupied bandwidth, and average and total power, make the R3131A a great choice for wireless design and troubleshooting.
