brief description

the r&s®cbt performs bluetooth® rf tests at extremely high speed. in addition to power, modulation, frequency and ber tests, the r&s®cbt carries out a variety of spectrum measurements without requiring any extra spectrum analyzers. while conventional bluetooth® testers sequentially measure power, modulation, frequency accuracy and also frequency drift, the r&s®cbt performs all these measurements in a single test cycle, which makes the instrument very fast in production 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.

  • r&s®cbtgo software for automatic testing

    r&s®cbtgo is a pc software application for remote control of the r&s®cbt and r&s®cbt32. the software can be downloaded free-of-charge from the rohde & schwarz website. using r&s®cbtgo, you can conveniently create any desired test sequences by configuring and combining selectable test modules. the software generates measurement reports at the press of a button. reports can be stored in various formats. r&s®cbtgo offers a number of sample sequences, e.g. for automatically performing the various bluetooth® rf test cases. the software allows a large number of graphical elements to be integrated into the measurement report and is thus a valuable tool in r&d and product verification.

  • bluetooth® rf test cases

    the r&s®cbt and r&s®cbt32 can be used for evaluating the following bluetooth® test purposes as described in the bluetooth® rf test specifications:
