ROHDE - SCHWARZ - CMD55 Digital Radiocommunication Tester ROHDE - SCHWARZ - CMD55 Digital Radiocommunication Tester The Rohde Schwarz CMD55 is capable of testing GSM1800 (formerly named PCN or DCS1800) and GSM1900 (formerly named PCS or DCS1900) mobile phones. The CMD55 combines small dimensions with high measurement accuracy and speed. The CMD55 range of capabilities includes all signaling, generator and measurement functions required for verifying the correct operation of the DUT (Device Under Test). Thanks to its fast go / no-go tests and accurate analysis using optional extensions, the CMD55 is equally well suited for R&D, production and high-end service and production. Additional CMD55 test capabilities: To 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.
