This user guide is specific to the Spectrum Master MS272xC (models MS2722C, MS2723C, MS2724C, MS2725C, and MS2726C). Additional instrument functions and descriptions of optional measurement capabilities are described in measurement guides. Refer to
“Measurement Guides” for a list of these guides and their Anritsu part numbers. Measurement guides are provided on the Documentation disc that is shipped with the instrument and are also available for download (at no charge) from the Anritsu web site. Refer to section
“Anritsu Reference Documents”.
The Spectrum Master 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, plus cell site and 802.11a/b/g interference testing. Options are available 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 or a USB flash drive. Stored measurements can be downloaded to a PC by using the included USB and Ethernet cables. 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.
