Rohde & Schwarz CBT Bluetooth Tester
The Rohde & Schwarz CBT Bluetooth Tester is a state-of-the-art solution designed for high-speed RF testing of Bluetooth® devices. This advanced tester performs comprehensive Bluetooth® RF tests including power, modulation, frequency, and bit error rate (BER) assessments. Uniquely, the CBT allows for a wide array of spectrum measurements on an active Bluetooth® connection without the need for additional spectrum analyzers. Unlike traditional Bluetooth® testers that sequentially execute tests, the R&S CBT accomplishes all measurements in a single test cycle, optimizing efficiency for manufacturing applications. In laboratory settings, it provides real-time traces for power, modulation, and spectrum outputs displayed on a large graphical interface.
