Measuring the spurious emissions of transmitters used in GSM, DCS 1800 and PCS 1900 networks requires highly complex test setups since con-ventional spectrum analyzers do not have the necessary dynamic range. To obtain this range, notch filters are used to suppress the useful sig-nal. The spectrum analyzers of the FSE family make it possible for the first time to verify com-pliance with stipulated limit values for spurious emissions within the transmission band and out-side the reception band without the use of notch filters. The measurement problem and its solution by means of FSE are described in the following by way of the example of a GSM base station.

In addition to the main function, power electronic circuits very often have to provide other essential functions such as interfacing with submodules to fulfill system design requirements. Power designs therefore include bus communications in combination with a microcontroller. This can easily lead to more complex designs that may have a negative impact on the conducted emission measurements. Sometimes these auxiliary functions generate emissions infrequently, making it challenging to locate and isolate the root cause. An instrument with a very fast FFT analysis capability is essential to find infrequent events efficiently.

Autonomous and semi-autonomous vehicles rely on a complex hardware and software architecture to gather and exploit information from numerous radar sensors. To generate reliable data, the sensors require an unobstructed view of the surroundings. The bumpers or radomes mounted in front of the sensors must not impair radar functionality. This requires extensive testing of the deployed plastic parts and their underlying polymer structure. The R&S®QAR50 is the ideal tool to characterize the material properties of polymers and their influence on the quality of the radar signal at an early design stage and in quality control of material development.
