In this paper, the latest version of the Fraunhofer USB front-end development, called the Flexiband, is presented. Thanks to its new modular concept, the Flexiband not only supports a set of pre-selected configurations but can also be set up for multi-antenna inputs, user selectable bandwidth, intermediate frequencies, and customized ADC sampling rates and resolutions. The Flexiband hardware and software components are described in detail. Different configurations are shown and one example of a recorded Galileo E1/E5a signal is analyzed.
