The R&SήCMW270 allows you to select only the options you require − from the non-signaling mode for high-speed RF alignment in production up to the signaling mode with a base station emulator for testing mobile devices in simu- lated network conditions. Moreover, you can keep your test costs to a minimum owing to the scalability, test speed, measurement repeat-ability, and accuracy of the R&SCMW270.Continuous frequency range for all WiMAX band classes > J up to 6 GHz > J Realtime signaling to verify network entry and functional performance, plus a message logger Vector signal analyzer (VSA)...

Realtime signaling allows you to optionally test the full functionality of a mobile station like in mobile WiMAX network operation, e.g. synchronization, ranging, and registration. The RF parameters of the WiMAX mobile station in the physical layer (PHY) and the protocol functions in the MAC layer are concurrently verified under realistic conditions. You can thus detect complex errors such as crosstalk between the transmit and receive paths. Test signal quality better than with golden device solutions The R&SCMW270 provides a much more reliable alter-native to golden devices, which require...

The R&SCMW270 measures all TX and RX parameters essential for producing WiMAX base stations and mobile stations cost-effectively while maintaining high quality. RF alignment is performed in the non-signaling mode, and the DUT is controlled directly via a test mode interface, e.g. for setting the RF paths and downloading calibration tables. Transmitter measurements with R&SήMulti-Evaluation To reduce test time, the R&SCMW-KM700 software op- tion enables the simultaneous analysis of a wide range of TX measurements by using the R&SήMulti-Evaluation concept. Different evaluations (power,...

Minimum uncertainty and maximum repeatability The low level uncertainty of the R&SCMW270 provides reliable data for maximizing yield in the mass production of mobile stations. The high dynamic range of the RF input and RF output levels means that all WiMAX measure- ments can be performed without any external passive and active RF components. The RF generator typically provides less than 0.3 dB level uncertainty and a repeatability of less than 0.05 dB for WiMAX band 1.Internal temperature sensors automatically adapt the mea-surement accuracy to the ambient conditions.No calibration is...

The R&SήCMW270 is of modular design and can easily be expanded with additional hardware and software op- tions. The state-of-the-art instrument architecture with its WindowsXP-based controller makes the instrument easy to use.The R&SήCMW270 does not include an integrated display since the instrument is primarily used on production lines, where remote control is standard. For standalone opera- tion, the instrument includes interfaces for a monitor, key-board, and mouse. Remote control The base unit of the R&SCMW270 is equipped with a Gigabit LAN interface and a USB 2.0 interface for remote...

A required step in the production of WiMAX mobile and base stations is the alignment of the RF transceiver. This includes measuring and interpolating variations in the fre-quency and level characteristics in both the transmit and receive paths ֖ and storing the data in correction tables. In later operation, compliance with RF level accuracy as specified in the IEEE 802.16e standard is thus ensured. Board level test: RF alignment in non-signaling mode After the WiMAX module has been assembled, the RF transceiver is aligned at the printed board level. Owing to the wide dynamic range and the...
