CMD55產(chǎn)品特點(diǎn)：
·是測量GSM及GSM1800移動(dòng)電話的緊縮式單元
·通過RS232，IEC/IEEE遠(yuǎn)控
·前面板有多功能連接器
·話音編碼器/解碼器可被集成
·可選擇安培表和伏特表
·高敏感度二級RF輸入
·可改進(jìn)為GSM、GSM1800及GSM1900測試
CharacteristicsThe
CMD52 is a compact unit for testing GSM900 mobiles. The CMD55 is
furthermore capable of testing GSM1800 (berly named PCN orDCS1800)
and GSM1900 (berly named PCS or DCS1900) mobile phones. Both models
are favourably priced and combine small dimensions with high
measurement accuracy and speed.The testers range of capabilities
includes all signalling, generator and measurement functions required
for verifying the correct operation of the DUT (Device Under Test).
Thanks to its fast go/nogo tests and accurate analysis using optional
extensions, CMD52 and CMD55 are equally well suited for R&D, production
and high-end service and production.Based on the wide-range know-how
of Rohde & Schwarz in digital radiocommunication testing, which not
least was obtained in developing type-approval test systems such as
the GSM900 and GSM1800 system simulators, both CMD models are top-
grade testers for present and future measurement applications.Test
capabilitiesTo test mobile phones, the CMD simulates a GSM900, 1800
or 1900 base station. One of the two RF synthesizers available for
this purpose delivers a continuous BCCH signal while the other one
provides all 8 timeslots for TCH signals.The major test functions are
:Mobile synchronizationLocation updateIncoming call setupOutgoing
call setupMobile power level controlHandover (channel change, timeslot
change)Peak power measurementHigh dynamic range burst analyzer

phoneCall bing by CMDDC current/voltage measurementsPhase and
frequency error measurement (option CMD-B4)Measurement of power
ramping as a function of time (option CMD-B4)Bit-error rate (BER)
and Fast BER measurement (option CMD-B4)OperationOperation of the
CMDis extremely user-friendly and requires no detailed GSM/PCN knowledge.
The high-contrast, backlit LCD provided with softkeys on both sides
allows convenient callup of test routines under menu control. Various
network-specific beters are preset and permit direct testing
without any operator control. In addition, it is of course possible
to modify all beters individually in the configuration menus.AutotestThe
autotest function enables complete measurement routines to be started
at a keystroke without any further intervention by the operator
being required. The test results in tabular b are displayed on
the screen.Remote controlThe CMD is remote-controlled via the RS-232
or IEEE/IEC-bus interface using SCPI-compatible commands. In the
remote-control mode the CMD is designed for fast speed to yield high
throughputs in production.Echo testThe echo test allows very rapid
go/nogo analysis covering all essential parts of the mobile. Words
spoken into the microphone of the mobile are sent to the CMD, stored
in buffer memory and sent back to the phone. In this way it is possible
to check the whole signal path from the microphone via the RF transmitter
section, RF receiver section, modulator, demodulator, signalling
section, speech coder/decoder, analog audio components through to
the loudspeaker.Testing handheldsIn addition to the normal RF b
/output, the CMD has a high-sensitivity b and a high-level output
which enable tests on modules or on handhelds with built-in antenna
by using couplers like the CMD-Z10.Module testingFault localization
in mobile bephones requires various measurement functions that can
also be used without signalling so that defective units can be tested
down to modular level. The basic model of CMD already provides some
of these functions, eg signal generation with or without modulation
or power measurements, other functions being available as optional
extensions.
