The MS2651B/2661B portable spectrum analyzers are ideal for analyzing the signals of above systems, device and related equipment.  They are fully synthesized spectrum analyzers covering a wide frequency range from 9 kHz to 3 GHz. They have superior basic performance such as high C/N ratio, low distortion, and high frequency/level accuracies and are easy to operate. In addition, they use resolution bandwidth filters with a much better selectivity than previously possible. The large selection of options is available to handle a wide range of applications at reasonable cost.
The MS2661B is designed for manufacture and installation of radio equipment and devices, while the MS2651B is meant for maintenance applications.
