Nearly all tests in accordance with the Bluetooth low energy test specification V4.0  can be performed using the R&S®CBT alone. Some tests additionally call for signal generators to provide interference signals. This application note describes the tests performed with additional equipment and presents straightforward solutions based on the R&S®CBTgo software.
With the recent introduction of the R&S®SMW200A microwave vector signal generator, Rohde & Schwarz now offers a novel approach to flexibly and conveniently generate multiple radar target echoes for systems up to 20 GHz. When used in combination with the R&S®FSW signal and spectrum analyzer, these commercial off-the-shelf (COTS) test instruments can be configured to support flexible radar target generation including range and target velocity emulation.
The R&S®SMBV100A is both, a versatile general-purpose vector signal generator and a powerful GNSS signal simulator. It can simulate up to 24 satellites in realtime for testing GNSS receivers flexibly, reliably, and cost-efficiently. The R&S®SMBV100A supports receiver testing under realistic conditions by offering features such as obscuration simulation and automatic multipath generation. Out of a multitude of possible test scenarios – with predefined or user-specific settings – this application note presents some examples to give an impression of the instrument’s capabilities.
Despite the advent of advanced digital transmission methods, analog broadcasting remains highly important. Until now, measurements on FM transmitters in connection with acceptance testing, commissioning and maintenance required using a variety of T&M instruments.
This aplication note offers two solutions to dealing with abruptly jumps -- up or down -- in oscillator frequency, causing a lost PLL lock or a variety of other system-related problems.
