The R&S CMW500 non-signaling tester delivers high speed, accuracy, and high scalability when used in the production of wireless devices. Featuring a frequency range up to 6 GHz and an IF bandwidth of 40 MHz/70 MHz (analyzer/generator), the production tester has been designed to anticipate future technological developments, This ensures minimum test costs and high safety of investment.
The R&S CMW500 one-box tester includes a powerful RF analyzer and generator. This combination plus a new test concept ensures maximum test performance, minimum space requirements, and comparatively low power consumption.
"Modern mobile phones are becoming more and more complex", says Anton Messmer, Director of the Mobile Radio Testers Subdivision. "The test effort increases with every new technology and every additional frequency band. To curb the growth in test times and costs, completely new approaches are needed. That's the reason Rohde & Schwarz developed the R&S Smart Alignment test concept for manufacturers of chipsets and wireless devices. By applying this test concept, alignment times are up to ten times faster than with conventional methods."
A prerequisite for minimum production costs is maximum first pass yield. Yield depends on optimizing the entire production process, where the measurement accuracy of the individual components involved is crucial. For this reason, very high standards – especially with regard to absolute accuracy, repeatability, and linearity – were set during the development of the R&S CMW500.
The R&S CMW500 presently supports GSM, GPRS, EDGE, WCDMA, mobile WiMAX, CDMA2000, and TD-SCDMA as options. Further technologies will follow. Rohde & Schwarz provides applications that allow extremely fast measurements.
With a frequency range of 3.3 GHz, the base unit supports all important mobile radio bands used today. Since the range can be easily extended from 3.3 GHz to 6 GHz with software, the tester is excellently positioned for future developments.
Due to the high stability of the R&S CMW500 design, users can extend the calibration interval to two years, generating further cost savings.
