Rohde & Schwarz announces a 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 ideal 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.

When operating in the signaling mode, the R&S CMW500 simulates the various functions of the base station and of the network in real time. The wireless device registers and establishes a connection. The various transmitter and receiver measurements are then carried out for each wireless technology and supported frequency band.

In comparison to RF-only measurements in the non-signaling mode, signaling procedures clearly require more time. After all, the devices under test (DUTs) are tested virtually under real conditions in the future network. Particularly with high-end multitechnology phones or during the introduction of new technologies such as 3GPP LTE, manufacturers want to avoid the risks associated with the initial stages. After devices and technologies have gained a foothold, users can later convert their production lines to the faster non-signaling tests thanks to the flexibility of the R&S CMW500.

In the case of production tests in the non-signaling mode, the wideband radio communication tester has already set standards: It achieves adjustment times that are up to ten times faster than conventional solutions. Moreover, the instrument supports all relevant cellular and non-cellular standards for measurements in production. The R&S CMW500 is the first all-in-one solution on the market that can be used in all phases of the development and production of wireless devices.
