The R&S CMD55 is a compact, portable unit capable of testing GSM mobile phones and furthermore GSM1800 and 1900 (DCS1800/1900).
The testers 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/nogo tests and accurate analysis using optional extensions, CMD55 is equally well suited for R&D, production and high-end service and production.
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.
The CMD is remote-controlled via the RS-232 or IEEE/IEC-bus interface using SCPI-compatible commands.
