The Anritsu MS2711B is a legacy member of the Spectrum Master series of handheld spectrum analyzers, covering a frequency range of 100 kHz to 3.0 GHz. Known for its lightweight, rugged, and battery-operated design, it is optimized for field applications such as wireless transmitter testing, site surveys, and base station maintenance. The MS2711B features a built-in preamplifier as standard, support for optional scalar analysis with a tracking generator, and powerful one-button wireless measurement routines.
