This product has been discontinued Replacement Model(s) : MS2719B , MS2687B , MS2830A Microwave , MS2830A

The MS2661C Portable Spectrum Analyzer is a synthesized spectrum analyzer covering a wide frequency range from 9 kHz to 3 GHz.

It has superior basic performance such as high C/N ratio, low distortion, and high frequency/level accuracies and is easy to operate.

It has a Measure function for evaluation of radio equipment that includes a frequency counter and one-button evaluation of C/N, adjacent channel power, occupied frequency bandwidth, and burst average power.

It has a large selection of options and application software packages.
