General Information
Introduction
This chapter provides a description, performance specifications, optional accessories, pre-
ventive maintenance, and calibration requirements for the Anritsu Handheld Spectrum Ana-
lyzer model listed below. Throughout this manual, this instrument may be referred to as a
Spectrum Master.

Model Frequency Range
MS2721A 100 kHz to 7.1 GHz

Description
Spectrum Master is a synthesizer-based hand held spectrum analyzer that provides quick and
accurate measurement results. Measurements can be easily made by using the main instru-
ment functions: frequency, span, amplitude and bandwidth. Dedicated keys for common
functions and a familiar calculator-type keypad are available for fast data entry.
Time and date stamping of measurement data is automatic. The internal memory provides
for the storage and recall of more than 1000 measurement setups and more than 1000 traces.
The bright daylight-viewable, high-resolution color liquid crystal display (LCD) provides
easy viewing in a variety of lighting conditions. Spectrum Master is capable of up to three
hours of continuous operation from a fully charged battery and can be operated from a 12
VDC source, which also simultaneously charges the battery.
Spectrum Master is designed for monitoring, measuring, and analyzing signal environments.
Typical measurements include: in-band interference, transmit spectrum analysis, plus cell
site and 802.11a/b/g interference testing. A full range of marker capabilities such as peak,
center and delta functions are provided for faster, more comprehensive analysis of displayed
signals. Upper and lower multi-segmented limit lines are available to create quick, simple
pass/fail measurements. A menu option provides for an audible alert when the limit value is
exceeded.
Anritsu Master Software Tools, a PC-based software program, provides for storing measure-
ment data. Master Software Tools can also convert the Spectrum Master display into several
graphic formats.
Measurements may be stored in either internal memory or the external Compact Flash.
Stored measurements can be downloaded to a PC using the included USB and Ethernet
cables. Once stored, the measurement can then be displayed, scaled, or enhanced with mark-
ers and limit lines. Historical graphs can be overlaid with current data using the PC mouse in
a drag-and-drop fashion. The underlying data can be extracted and used in spreadsheets or
for other analytical tasks.
