The MS2711D also features several dedicated
one-button measurements that make testing cellular, DCS/PCS and WLAN systems
among other wireless systems easier than ever before. Measurements include
channel power, adjacent channel power ratio, and occupied bandwidth measurements
that can confirm the distortion level or channel power level of an AMPS, TDMA,
CDMA or GSM transmitter. Additionally, the MS2711D can conduct a series of
spurious measurements when analyzing a wireless base station transmitter, while
the field strength mode allows users to measure propagation and coverage, or to
pinpoint electromagnetic (EM) leakage in broadcast systems. Measurement of
carrier to interference has been added; This measurement is targeted for
measurements of 802.11 a, b, and g access points. Other features include trace
averaging for more accurate noise measurements; a multilingual user interface
with on-screen menus and messaging in 6 different languages; and a 50-ohm
interface that is adaptable to 75-ohms, enabling users to conduct measurements
of 75-ohm systems without sacrificing measurement accuracy.
The MS2711D includes data analysis software, soft
carrying case, rechargeable/field-replaceable battery, AC/DC power supply, and
12.5V automobile cigarette lighter adapter and users

Applications
Convenient operating procedures, high sensitivity, and
excellent repeatability enable the MS2711D to pinpoint the smallest system
performance degradation and allow for easy verification of system compliance.
Typical applications include:
- Transmitter Spectrum Analysis - occupied bandwidth, channel
power, adjacent channel power ratio, modulation and antenna gain/isolation
measurements
- Receive Signal Analysis - location and identification of
in-band interference and out-of-band spurious signals; modulation
identification, modulation depth, deviation and spectral mask
- Signal Strength Mapping - to determine the most suitable
location for antennas, base stations and repeaters
- Stimulus-response measurements - for component test.
