In two experiments, we developed an open-source, high-performance, non-invasive BCI speller and examined its feasibility for free communication. It is therefore not clear whether naïve users are able to achieve such high rates with the added cognitive load of genuine free communication, which involves continuously generating and spelling novel words and phrases. While impressive, these rates are typically calculated for experienced users repetitively typing single phrases. To date, the highest performing spellers report typing rates of ~10.00 words/minute. Brain-computer interface (BCI) spellers often achieve this by decoding patterns of neural activity as users attend to flickering keyboard displays. While manual keyboards currently allow us to interface with computers and manifest our thoughts, a next frontier is communication without manual input.

All described measurements were performed using the R&S®SMBV100A vector signal generator and the R&S®FSV spectrum analyzer.Free communication is one of the cornerstones of modern civilisation. 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. 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. This is followed by a description of the construction and functioning of analog and vector signal generators. The first part of this educational note presents the applications for and the most important types of signal generators. 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. Signal generators play a vital role in electrical test and measurement. Modulation and Signal Generation with R&S®Signal Generators and any use of such marks by Rohde & Schwarz is under license.

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. This application note describes how to use the R&S CMW platform to perform the measurements defined in Bluetooth test specification version 5. To save time and money, performance tests need to be performed in the development stage. Before a new product with Bluetooth functionality can be launched, the qualification process defined by the Bluetooth SIG must be successfully completed. Due to its popularity, one of the most important standards is Bluetooth (or Bluetooth Low Energy). These different things use a variety of wireless technology standards to establish a connection. Even clothing with sewn-in sensors to measure vital functions can now connect to the Internet and transmit data to cloud services. are now connected to the Internet, forming what is known as the "Internet of Things".
