Power converters with a full-bridge topology are frequently used in telecommunications and servers that need to be compact, efficient and cost sensitive, making them more complex. Switching patterns for all the main primary switches including synchronous rectifier switches need to be validated after the first protype is built. This complex validation requires proper measurement of switching patterns to prevent catastrophic switching patterns. Expertise and the right measurement tools are essential when identifying unexpected events in the converter switching process.

Especially with test receivers not comprising a built-in disk drive (ESHS10, ESVS10, ESVD, ESVB and ESPC) it is necessary to store instrument settings before a firmware update or before changing the battery of the static memory to be able to restore the settings later on. Frequently it is desirable to exchange settings or comprehensive data like transducer sets between receivers, or receivers have to be set up to suit different applications.

Vector network analyzers are used in high frequency applications to measure the complex scattering parameters of an unknown device-under-test (DUT). In general, the DUT characteristics can be evaluated by using electromagnetic waves. The correlation between the incident, reflected and transmitted wave quantities at the DUT is defined by its scattering matrix S.

Signal generators play a vital role in electrical test and measurement. They generate the test signals that are applied to components such as filters and amplifier, or even to entire modules, in order to ascertain and test their behavior and characteristics. The first part of this educational note presents the applications for and the most important types of signal generators. This is followed by a description of the construction and functioning of analog and vector signal generators. To permit a better understanding of the specifications found on data sheets, a closer look at the most important parameters for a signal generator is provided.Beyond the output of spectrally pure signals, a key function of RF signal generators is the generation of analog- and digitally modulated signals. The second part of this note therefore presents the fundamentals for the most significant analog and digital modulation methods.The third part of this educational note contains exercises on the topics of analog and digital modulation. All described measurements were performed using the R&S®SMBV100A vector signal generator and the R&S®FSV spectrum analyzer.

Audio Analyzers UPD and UPL with their large variety of functions provide practically all measurement procedures required in audio technology. Thanks to the Universal Sequence Controllers UPD-K1 and UPL-B10, which are available as options, the user is able to considerably expand the range of functions to suit his particular requirements. It is possible, for instance, to add complete measurement functions - eg measurement of ohmic resistance - and to read out, convert or reload sweep results or to add new scale labelling (eg group delay). Another example is the analysis of sweep curves and the display of results in a window next to the curve. As far as softkey labelling and functions are concerned, operation of the sequence control programs is analogous to the softkey control of the UPD/UPL graphics display.
