The R&S CBT performs Bluetooth® RF tests at extremely high speed. Besides power, modulation, frequency and BER tests, the Rohde & Schwarz CBT carries out a variety of spectrum measurements on an active Bluetooth® connection without requiring any extra spectrum analyzers. While conventional Bluetooth® testers sequentially measure power, modulation, frequency accuracy, and, last but not least, frequency drift, the R&S®CBT performs all these measurements in a single test cycle, which makes the unit very fast in manufacturing applications. For use in the lab, the R&S®CBT offers traces for power, modulation and spectrum, which are output in realtime on a large graphical display.
