Rohde & Schwarz exhibits advanced T&M solutions that address emerging challenges in consumer electronics development at CETEX Consumer Electronics Test & Development Forum and Expo at RAI in Amsterdam.

The tried and tested R&S®CMW270 Wireless Connectivity Tester can be used to test the RF characteristics of receivers and transmitters, and to determine the data throughput in the transmit and receive directions. The R&S®CMW270 is the reference system for testing IEEE 802.11ax devices under realistic operation conditions.

Video Overview for CMW270 product videos

Using the well-established R&S CMW270, developers can test the RF characteristics of both transmitters and receivers and also determine the data throughput in both directions.
