Rohde & Schwarz production tester handles wireless devices up to 6 GHz

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 6 GHz and an IF bandwidth of 40 MHz/70 MHz (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 standards—especially with regard to absolute accuracy, repeatability, and linearity—were 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 3.3 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.

The R&S CMW500 is now available from Rohde & Schwarz. In eithere the GSM/GPRS/EDGE/WCDMA or CDMA2000 configuration, the U.S. list price starts at $60,000.
