The Anritsu MS2661C is a synthesized portable spectrum analyzer covering a wide frequency range from 9 kHz to 3 GHz. Designed for signal analysis of radio and other electronic equipment, it offers exceptional basic performance, including a high carrier-to-noise (C/N) ratio, low distortion, and superior frequency and level accuracies. Built-in measure functions facilitate evaluation of radio equipment parameters, such as adjacent channel power, occupied bandwidth, burst average power, and template decision with supporting dual-screen and FM demodulation displays.
