Play-only devices like CD- or MP3 players cannot be measured as traditional 4-pole devices. Therefore traditional transfer function measurements using the generator part of the audio analyzer are not possible. Those devices are tested with a pre-recorded test signal available as wav or MP3 file. This application note describes a fast test together with a setup and an executable which runs the test and displays the desired results. The test signal is provided as a linear coded wav file. This file can easily be coded into MP3 format using any commercially available or public domain wave editors or ripper programs. The test can also be executed by IEEE control and all results can be read out by IEEE commands.

5G is the fifth generation of wireless communication technology supporting cellular networks. From GSM (2G) through to LTE (4G), each generation addresses technical challenges not overcome by its predecessor. As with previous generations, 5G requires new mobile devices and new base stations (BTS).Unlike previous generations, the use of radio beams in 5G requires completely new approaches with regard to the compliance, coverage, and quality of service testing.The new air interface is called 5G NR ("new radio"). This application note describes the measurement challenges of 5G NR and makes clear the benefits of using a monitoring receiver for measuring 5G signals.Real-world examples explain how to perform various key 5G measurements. The final section covers further 5G measurement possibilities using R&S products. "Over-the-air" (OTA) measurements are essential in 5G. This means staff from regulators and operators must work in unknown radio environments that vary according to location (e.g. urban or suburban) and mission (e.g. 5G BTS compliance testing or interference hunting). Measurement equipment must operate in a wide range of scenarios (close to the mast and far from the mast) and offer user-friendly functionality that enables the required measurements.Considering current global deployment trends, this paper focuses on the FR1 frequency band (sub 6 GHz).

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.
