          CharacteristicsThe
          CMD52 is a compact unit for testing GSM900 mobiles. The CMD55 is
          furthermore capable of testing GSM1800 (formerly named PCN orDCS1800)
           and GSM1900 (formerly 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
          (option CMD-B4 and CMD-B42)Spectrum due to Switching measurement
          (option CMD-B4 and CMD–B43)Spectrum due to Modulation measurement
          (option CMD-B4 and CMD–B43Timing Advance measurementSACCH measurement
           (eg RxLev, RxQual, power level)Echo testCall clearing by mobile
          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 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 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 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 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 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.
