Characteristics

甩卖CMD55 CMD55综合测试仪CMD55 CMD55

The 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 capabilities

To test mobile phones, the CMD simulates a GSM900, 1800 or 1900 base station. One of the **o RF synthesizers available for this purpose delivers a continuous BCCH signal while the other one provides all 8 timeslots for TCH signals.
