The Anritsu MS2721B Spectrum Master is a handheld, battery-operated spectrum analyzer designed for applications up to 7.1 GHz. Weighing less than 7 pounds, it is highly portable and well-suited for field and bench engineering tasks. The instrument features a built-in preamplifier, a low Displayed Average Noise Level (DANL) of < -163 dBm at 1 GHz, and exceptional phase noise characteristics, making it ideal for analyzing 802.11a, 3G, WiMAX, broadcast AM/FM, and cellular signals. It supports numerous optional measurements including WCDMA, GSM/EDGE, HSDPA, fixed WiMAX, and a 400 kHz to 7.1 GHz tracking generator.
