The R&S CMW500 non-signaling tester for wireless devices delivers high speed, accuracy and high scalability.

The 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.

Featuring a frequency range up to 6GHz and an IF bandwidth of 40MHz/70MHz (analyzer/generator), the CMW500 has been designed to anticipate future technological developments and to ensure minimum test costs and high safety of investment.

Maximum first-pass yield is prerequisite for minimizing production costs and this requires optimizing the entire production process, including test. Measurement accuracy of the individual components involved is crucial. For this reason, very high standardsespecially with regard to absolute accuracy, repeatability and linearitywere set during the development of the R&S CMW500.

"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."

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 3.3GHz, the base unit supports all important mobile radio bands used today. Since the range can be easily extended from 3.3GHz to 6GHz 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.

The R&S CMW500 is now available from Rohde & Schwarz. In either the GSM/GPRS/Edge/W-CDMA or CDMA2000 configuration, the U.S. list price starts at $60,000.
