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.

In environments such as mobile use as well as in service shops and education, spectrum analyzers with dedicated built-in pulsed-signal analysis features are often not available. This paper describes the smartphone app Pulsed RF Calculator that aids in finding the right choice of spectrum analyzer settings to calculate the so-called pulse desensitization for manual compensation of pulsed signal amplitudes. Automatic compensation and many other features necessary for in-depth pulsed signal analysis require the use of dedicated functionalities and are outside the scope of this app.

This white paper summarizes significant additional technology components based on LTE, which are included in 3GPP Release 12 specifications. The LTE technology as specified within 3GPP Release 8 was first commercially deployed by end 2009. Since then the number of commercial networks is strongly increasing around the globe. LTE has become the fastest developing mobile system technology ever. As other cellular technologies LTE is continuously worked on in terms of improvements. 3GPP groups added technology components according to so called releases. Initial enhancements were included in 3GPP Release 9, followed by more significant improvements in 3GPP Release 10, also known as LTE-Advanced. Beyond Release 10 a number of different market terms have been used. However 3GPP reaffirmed that the naming for the technology family and its evolution continues to be covered by the term LTE-Advanced. Therefore LTE-Advanced remains the correct description for specifications defined from Release 10 onwards, including 3GPP Release 12.
