This application note shows how to perform Bluetooth transmitter measurements with the CMU200 in a reduced signaling mode, in which the protocol handshake between the Bluetooth Equipment Under Test, the EUT, and CMU200 is skipped. This additional CMU200 feature allows both more flexible and faster RF testing of Bluetooth modules. A step-by-step example with SMIQ demonstrates the principles and serves as a reference for integrating this method in user-specific test strategies.

The Rohde & Schwarz Bluetooth RF test solution with the R&S®CMW and R&S®CMWrun is closely aligned to the Bluetooth RF Test Suite. Most of the tests can be performed with the equipment under test connected to a single CMW which is remotely controlled via R&S®CMWrun running on an external computer. Some of the tests require an additional signal generator. This document describes common setups for these tests and the required configurations.

This document describes the adaptive frequency hopping mechanism for improved signaling performance in Bluetooth Basic Rate and Enhanced Data Rate devices.The R&S CMW provides this feature for remote operation in TX, Loopback and Connection test mode. Thereby the R&S CMW acts as a master, while the Equipment under Test (EUT) represents the slave(s) of the piconet.

Modern mobile phones can support cellular and noncellular wireless communications standards at the same time. This means, however, that the subsystems must operate in very close proximity to each other within a single device (in-device coexistence). The resulting high level of reciprocal leakage can at times cause considerable interference.This application note employs preliminary theoretical analysis and demonstrates how the problems of indevice coexistence can be measured.

Nearly all tests in accordance with the test specification* can be performed with the R&S® CMU200/CBT alone. Some tests additionally call for signal generators to provide interference signals and also require spectrum analyzers. This application note describes the tests performed with additional equipment and presents straightforward solutions based on the CBTgo software.
