CMD55产品特点:
·是测量G***及G***1800移动电话的紧缩式单元
·通过RS232,IEC/IEEE远控
·前面板有多功能连接器
·话音编码器/***器可被集成
·可选择安培表和伏特表
·高敏感度二级RF输入
·可改进为G***、G***1800及G***1900测试
CharacteristicsThe
CMD52 is a compact unit for testing G***900 mobiles. The CMD55 is
furthermore capable of testing G***1800 (formerly named PCN orDCS1800)
and G***1900 (formerly named PCS or DCS1900) mobile phones. Both models
are f***ourably priced and combine ***all dimensi*** with high
measurement accuracy and speed.The testers range of capabilities
includes all signalling, generator and measurement functi*** required
for verifying the correct operation of the DUT (Device Under Test).
Thanks to its fast go/nogo tests and accurate analysis using optional
extensi***, CMD52 and CMD55 are equally well suited for R&D, production
and high-end service and sed 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 G***900 and G***1800 system simulators, both CMD models are top-
grade testers for present and future measurement applicati***.Test
capabilitiesTo test mobile phones, the CMD simulates a G***900, 1800
or 1900 base station. One of the two RF synthesizers ***ailable for
this purpose delivers a continuous BCCH signal while the other one
provides all 8 timeslots for TCH signals.The major test functi*** are
:Mobile synchronizationLocation updateIncoming call setupOutgoing
call setupMobile power level controlHandover (channel change, timeslot
change)Peak power measurementHigh dynamic range burst analyzer
(option CMD-B4 and CMD-B42)Spectrum due to Switching measurement
(option CMD-B4 and CMD–B43)Spectrum due to Modulation measurement

phoneCall clearing 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 G***/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 parameters are preset and permit direct testing
without any operator control. In addition, it is of course possible
to modify all parameters 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 form are displayed on
the mote 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 ho testThe echo test allows very rapid
go/nogo analysis covering all essential parts of the mobile. Wo***
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 tran***itter
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 input
/output, the CMD has a high-sensitivity input 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 telephones requires various measurement functi*** 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 functi***, eg signal generation with or without modulation
or power measurements, other functi*** being ***ailable as optional
extensi***.
