1-7 Instrument Description
The Spectrum Master MS272xB is a synthesizer-based handheld spectrum analyzer that
provides quick and accurate measurement results. Measurements can be easily made by
using the main instrument 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 up to 1000 measurement setups and up to 1000 traces using
Master Software Tools (MST). External storage can be used for bulk measurement storage.
The bright daylight-viewable, high-resolution, color liquid crystal display (LCD) provides
easy viewing in a variety of lighting conditions. The Spectrum Master is capable of up to
2.5 hours of continuous operation from a fully charged battery and can be operated from a
12 VDC source, which also simultaneously charges the battery.
The Spectrum Master is designed for monitoring, measuring, and analyzing signal
environments. Typical measurements include: in-band interference and transmit spectrum
analysis, digital television transmitter testing and analysis (in models MS2721B and
MS8911B), plus cell site and 802.11a/b/g interference testing. Options are available (for
models MS2721B, MS2723B, and MS2724B for RF, advanced demodulation, and
over-the-air (OTA) measurement. 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 a limit value is
exceeded.
In transmitter analyzer mode, the Spectrum Master displays six markers and the marker
table in Code Domain Power and Codogram displays. In Spectrum Analyzer mode, a full
range of marker capabilities is provided. Markers are not available in GSM mode.
Anritsu Master Software Tools, a PC-based software program, provides for storing
measurement data. Master Software Tools can also convert the Spectrum Master display into
several graphic formats.
Measurements may be stored in the internal memory, a USB flash drive, or the Compact
Flash memory. Stored measurements can be downloaded to a PC by using the included USB
cable and Ethernet cable. After being stored, the graphic trace can then be displayed, scaled,
or enhanced with markers and limit lines. Historical graphs can be overlaid with current data
by using the PC mouse in drag-and-drop fashion. The underlying data can be extracted and
used in spreadsheets or for other analytical tasks.
