1-4 Description
The MT8221B BTS Master is an integrated multi
-
functional base station test tool that
eliminates the need to carry and to learn to use multiple test sets. The MT8221B
measurement capabilities include: spectrum analyzer smart measurements, precision return
loss, VSWR, cable loss, distance
-
to
-
fault, two port gain/loss, one-port and two-port magnitude
and phase, interference analysis, spectrogram, and power meter.
RF, advanced demodulation, and over-the-air (OTA) measurements can be applied to
WCDMA/HSDPA, GSM/GPRS/EDGE, Fixed WiMAX, Mobile WiMAX, CDMA and EVDO,
DVB-T/H, TD-SCDMA, LTE, and TD-LTE.
Additional capabilities include a Vector Signal Generator (VSG), GPS location information,
enhanced frequency reference oscillator accuracy, T1 measurements (including Vpp),
E1 - 2 Mb/s measurements, T3 measurements, and listening to DS0/VF channels.
The BTS Master base model has cable and antenna analysis (MT8221B: 400 MHz to 4.0 GHz,
MT8222B: 400 MHz to 6.0 GHz), spectrum analysis (150 kHz to 7.1 GHz), and an internal
power meter (10 MHz to 7.1 GHz). The cable and antenna analysis is performed by a Vector
Network Analyzer that is designed to make accurate vector-corrected 1-port and 1-path,
2-port magnitude and phase measurements from 400 MHz to 6 GHz.
The MT8221B BTS Master is also a synthesizer
-
based 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
one-button measurements of field strength, channel power, occupied bandwidth, Adjacent
Channel Power Ratio (ACPR), and Carrier to Interference Ratio (C/I) make the handheld
MT8221B the ideal choice for the field. A familiar calculator
-
type keypad allows for fast data
entry.
In transmitter analyzer mode, the MT8221B BTS Master displays 6 markers and the marker
table in Code Domain Power and Codogram displays. In Spectrum Analyzer mode, 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. A vertical line marker is
available with the histogram displays of BERT measurements in the T1/T3 Analyzer.
Markers are not available in GSM mode.
Time and date stamping of measurement data is automatic. The internal memory provides
for storage and recall of traces and measurement setups. The bright daylight
-
viewable,
high
-
resolution, color liquid crystal display (LCD) provides easy viewing in a variety of
lighting conditions. The BTS Master is capable of approximately 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.
Anritsu Master Software Tools (MST), a PC
-
based software program, provides a convenient
means for storing measurement data. Master Software Tools can also convert measurements
from the BTS Master display into several graphic formats. Master Software Tools supports
all of the options that are provided with the BTS Master.
