Rohde & Schwarz recently presented the new signaling mode of the R&S CMW500 for production tests on wireless devices. The wideband radio communication tester simulates a wireless connection and then performs transmitter and receiver measurements. This makes the R&S CMW500 suited both for signaling and non-signaling tests. Since both test concepts are used in production, the tester is a safe investment for manufacturers. As a flexibly scalable multi-standard platform, the R&S CMW500 also covers all phases in the development of a wireless device. In the production of wireless devices, the adjustment of individual modules is usually carried out in the non-signaling mode. Signaling tests are primarily used for the verification of the entire device at the end of the production line. The R&S CMW500 wideband radio communication tester can now handle signaling tests as well as non-signaling tests.
