More and more everyday items such as household appliances, vehicles, lights, etc. are now connected to the Internet, forming what is known as the "Internet of Things". Even clothing with sewn-in sensors to measure vital functions can now connect to the Internet and transmit data to cloud services. These different things use a variety of wireless technology standards to establish a connection. Due to its popularity, one of the most important standards is Bluetooth (or Bluetooth Low Energy). Before a new product with Bluetooth functionality can be launched, the qualification process defined by the Bluetooth SIG must be successfully completed. To save time and money, performance tests need to be performed in the development stage. This application note describes how to use the R&S CMW platform to perform the measurements defined in Bluetooth test specification version 5. As an alternative solution, we also cover how to perform almost all of the measurements with a spectrum analyzer and signal generator.The Bluetooth® word mark and logos are registered trademarks owned by Bluetooth SIG, Inc. and any use of such marks by Rohde & Schwarz is under license.

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).

This application note is about creating your own battery model for the R&S®NGM200 and R&S®NGU201, beyond the standard models provided within the battery simulation option NGM-K106 and NGU-K106. To get to a battery model, a few steps are required. To determine the parameters for the battery model, it is necessary to discharge a battery using a selected method, to record the data and to calculate the model on this basis. With this software, a connection can be established to the instrument, batteries can be measured using various measurement methods, and a model can then be created from these measurements. These models, which are determined from the measurements, can then be simulated with the power supply, thus creating a digital twin of the battery. Using these, test scenarios can be carried out in a safe and reproducible environment.
