Rohde & Schwarz CBT32

Rohde & Schwarz CBT32 Bluetooth Tester

The R&S CBT32 performs Bluetooth RF tests at very fast speed. In addition to power, modulation, frequency and BER tests, the Rohde & Schwarz CBT32 performs a variety of spectrum measurements on an active Bluetooth ^® connection without requiring any extra spectrum analyzer test equipment. While conventional Bluetooth ^® test equipment sequentially measure power, modulation, frequency accuracy, and frequency drift, the R&S CBT32 performs all these tests in a single cycle, which makes the CBT32 extremely quick in manufacturing evironments. For use in the laboratory, the R&S CBT32 offers traces for power, modulation and spectrum, which are output in real-time. An external display is required
