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 *all 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 *ysis 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 di*al radiocommunication testing, which not least was obtained in developing t*e-approval test systems such as the GSM900 and GSM1800 system simulators, both CMD models are *- 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 *yzer (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 *ysis 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 tran*itter section, RF receiver section, modulator, demodulator, signalling section, speech coder/decoder, *og 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
