Product Overview

Rohde & Schwarz CBT Bluetooth Tester

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.

Features of the R&S CBT include:

Power

• Nominal power, peak power, leakage power
• Power control
• EDR: relative Power

Timing

• Packet timing error
• EDR: guard time

Spectrum

• 20 dB bandwidth, adjacent channel power (ACP), frequency range
• EDR: in-band spurious emissions (gated ACP)

Modulation

• Average, maximum and minimum frequency deviation
• EDR: RMS DEVM, Peak DEVM, 99% DEVM
• EDR: differential phase encoding
• EDR: I/Q constellation diagram
• EDR: phase difference characteristic

Frequency

• Frequency accuracy (ICFT), frequency drift, maximum drift rate
• EDR: carrier frequency stability ω_i and ω₀
