New capabilities have been added to the CBT Series of Bluetooth RF testers from Rohde & Schwarz. The CBT-B41 hardware option adds two multitone generators and two audio analyzers to allow manufacturers to create test scenarios for Bluetooth equipment evaluation. The CBT-K54 software option provides the audio profiles commonly used in hands-free equipment. The CBTGo software includes four new transmitter and receiver measurements in accordance with the EDR test specification, and the CBT-B42 hardware option offers new digital audio interfaces in support of that aspect of Bluetooth connectivity.
