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

 change)Peak power measurementHigh dynamic range burst analyzer

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.
