The R&S®SMC100A signal generator offers a remote emulation feature that makes it possible to control the instrument by commands other than the built-in native SCPI commands. This feature allows the user to replace signal generators, e.g. from other manufacturers, with the R&S®SMC100A without having to change the remote control code. This application note describes how to use the remote emulation feature in general. Furthermore, it describes in detail the remote emulation for each supported instrument, limitations of the individual emulations and the remaining differences between the emulated and the original commands.

Level or power measurement of especially modulated signals using spectrum analyzers is becoming more and more important . Whereas the first choice in terms of accuracy for power measurement of any carrier (modulated or non-modulated) is a power meter, power measurement of spurious or in the adjacent channel of a transmission system needs a selective power meter with high dynamic range. A power meter, however, is a non-selective device with limited dynamic range and is not appropriate for these types of measurements. The first choice is a spectrum analyzer because of its versatile use as a general-purpose instrument. Compared to a power meter its power measurement accuracy is worse. In general this can be overcome by substitution methods using a power meter, an attenuator and a signal generator. But substitution is time-consuming and requires more investment in test equipment than a single instrument. Therefore it is most important to have a spectrum analyzer like the FSE, which can fulfill at least most of the requirements in terms of measurement accuracy.

Analog-to-digital converters (ADCs) have taken giant steps in speed and accuracy over the past years: Such devices allow high-speed video processing and even software defined radio (SDR) applications, where digitization is being performed at ever-higher intermediate frequencies (IF). This has clearly raised the bar for ADC test equipment, especially regarding the noise performance of the analog input signal and sample clock sources used in the test setup. The R&S®SMA100B offers outputs for the analog input signal of the ADC as well as the clock input signal in one single instrument - both with outstanding signal purity.

The aim of channel sounding is to characterize a radio channel by decomposing the radio propagation path into its individual multipath components. This application note provided by Neul describes how channel sounding can be performed using the R&S SMBV100A Vector Signal Generator and the R&S FSL Spectrum Analyzer. To illustrate the procedure reference is made to 8 MHz wide white space channels in the UK.

Vector network analyzers are used in high frequency applications to measure the complex scattering parameters of an unknown device-under-test (DUT). In general, the DUT characteristics can be evaluated by using electromagnetic waves. The correlation between the incident, reflected and transmitted wave quantities at the DUT is defined by its scattering matrix S.

Signal generators play a vital role in electrical test and measurement. 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. The first part of this educational note presents the applications for and the most important types of signal generators. This is followed by a description of the construction and functioning of analog and vector signal generators. 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. 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. All described measurements were performed using the R&S®SMBV100A vector signal generator and the R&S®FSV spectrum analyzer.

This application note is based on collaborative work between Cadence and Rohde & Schwarz.The focus is on understanding as early as possible in the design process performance enhancements through linearization of non-linear devices, in our case the RF power amplifier (PA). In other words, what performance benefits can be reached with linearization techniques such as digital predistortion (DPD). Typically, this is investigated when the device is available and physical RF measurements are conducted. In this application note, it is looked at earlier in the design process while using electronic design automation (EDA) such as Cadence® AWR® Visual System Simulator™ (VSS) software. The goal is to allow an RF designer to evaluate the linearizability of his design without in-depth knowledge of DPD algorithms. In the end, the designer can get closer to the optimal efficiency with earlier access to DPD, while at the same time improving time-to-market.The application note brings code examples and an exemplary setup for VSS software to provide an easy start to replicate and use the described procedure.
