The Rohde & Schwarz CBT Bluetooth Tester delivers comprehensive RF and audio measurements for Bluetooth device development and manufacturing. Qualified by the Bluetooth SIG for RF measurements, the CBT performs simultaneous power, modulation, frequency, and frequency drift analysis in a single test cycle – enabling rapid throughput in production environments. Transmitter measurements span power, modulation (GFSK, DPSK, π/4-DQPSK, 8DPSK), frequency accuracy, spectrum, timing, BER/PER, and constellation diagrams. Receiver quality and audio measurements include signal generation/reception, crosstalk, echo cancellation, microphone testing, and frequency response in single-tone and multi-tone modes. The instrument supports Bluetooth 1.2 through 4.2 and BLE standards.
