Using R&S®ELEKTRA Migration Tool
The R&S®ELEKTRA EMC test software is the successor of the R&S®EMC32 EMC measurement software. Like the R&S®EMC32 EMC measurement software, the R&S®ELEKTRA offers a solution that controls complete EMC systems and automates measurements on equipment under test (EUT) that is being tested for emissions (EMI) and immunity (EMS) compliance. It has more features and test types compared to R&S®EMC32.As both software platforms use different file formats, R&S®EMC32 users who upgrade their existing software to the R&S®ELEKTRA platform need to perform a file conversion before migrating their data to the R&S®ELEKTRA platform. This is done by using the R&S®ELEKTRA Migration Tool, which is installed automatically with each R&S®ELEKTRA installation.This Application Note describes how to use the R&S®ELEKTRA Migration Tool (version 4.4 onwards) for converting the backup data into the XML format that can be interpreted by the R&S®ELEKTRA software. It also provides recommended conversion steps (Chapter 5) and troubleshooting tips (Chapter 6). For instructions on migrating the data using R&S®ELEKTRA Migration Tool below version 4.4, refer to the R&S®ELEKTRA user manual. For better user experience, we recommend using the latest software version for migration.This Application Note does not describe the steps to backup data using the R&S®EMC32 or R&S®ES-SCAN software. For procedures on how to do so, refer to their respective manuals.

Power amplifiers in digital TDMA mobile phones are fed with current only during the active slot to save power. Using conventional measuring equipment, the noise figure, an important parameter in power amplifiers, can only be determined with the amplifier in continuous operation. However, continuous operation can lead to amplifier overload and produce distorted results. Now there is a convenient way of determining the noise figure of amplifiers with pulsed power supply: using a Spectrum Analyzer (FSP or FSE or FSIQ or ESI), Noise Measurement Software FS-K3 and a function or pulse generator.
