All types of information transmission, including the 'one-way' transmission used in broadcasting, involve feeding a radio frequency (RF) signal to an antenna. This is the essence of the most basic type of transmitter used to emit electromagnetic waves. In the real world, however, a transmitter used for broadcast applications, for example, is much more complex in terms of its functions and design. The different transmitter components must be carefully coordinated. There are many quality parameters that are critical in ensuring that a proper output signal is delivered. Rohde & Schwarz designed the R&S® ETL TV analyzer especially for broadcasting applications. The analyzer allows the measurement of the quality parameters that are relevant in analog and digital broadcasting. This Application Note describes the typical quality measurements performed during compliance testing of TV transmitters. The approach discussed here is based on the example of Rohde & Schwarz terrestrial transmitters for analog TV and DVB-T/H.

Embedded power supplies combine traditional power supply components with multiple sensors, processing and control logic as well as digital communications interfaces. Test equipment for debugging requires isolated input channels for measurements of hazardous voltages. Additional digital channels support the analysis of digital signals, while trigger and decode capabilities are essential for time-correlated monitoring of serial protocol-based communications interfaces.

In addition to frequency, power and long-term stability, short-term stability or its equivalent, phase noise, is an important characteristic of signal sources. For example, the phase noise of conversion oscillators of receivers obtained in the presence of a strong signal determines adjacent-channel sensitivity. In the case of transmitters, the phase noise of the oscillator together with the modulator characteristics is responsible for the power generated in adjacent channels. The phase noise of oscillators or synthesizers and the relevant measurements therefore play an important role in radio transmission systems.

As well as static tests, modern mobile communication standards also stipulate measurements under fading conditions, sometimes with additional white gaussian noise AWGN. Rohde & Schwarz supports these tests with the combination of the R&S®CMU200 Radio Communication Tester and the R&S®SMU200A or R&S®AMU200A Vector / Baseband Signal Generator and Fading Simulator. Applying fading and noise always raises the crest factor of a signal considerably. Thus, automatic path attenuation inside the Rohde & Schwarz baseband fader prevents the new signal peaks from being clipped at I/Q full scale. Any additional attenuation in the baseband, however, makes the RF output fall below its intended level. This application note shows how to achieve an accurate RF output level by compensating for the I/Q attenuation - without modifying the test setup or using additional instruments.

A turnkey 5G Field-to-Lab solution based on R&S®CMX500
5G New Radio (NR) is the fifth-generation radio interface and radio access technology (RAT) which was officially published by 3GPP in release 15. With the 5G technology, it enters a new era to meet the ever-increasing demands of mobile communications not only in the conventional cellular communication world, but also in the vertical industries.Since the commercialization of 5G NR, worldwide 162 networks have been deployed as per the report of GSA. On the path to the 5G NR network commercialization and service launch, field test is one of the essential user centric processes that User Equipment (UE) vendors should go through. Sophisticated features and versatile deployment options have to be thoroughly checked to ensure the reaching of certain confidence level before the official launch.However, field test is often linked with some challenges, such as► High costs due to the extensive drive tests► Time tedious analysis of a drive test that lowers the efficiency► Lack of test repeatability that makes the regressing tests impossibleWhat if providing an alternative solution in a laboratory environment to cope with all above mentioned challenges during the field test? R&S® as a world-wide well established test measurement equipment manufacturer and solution provider developed a 5G field-to-lab (F2L) turn-key solution, R&S®CM360°. It features► the simulation of the network with the real network configurations to avoid the cost intensive drive test by utilizing mobile radio tester R&S®CMX500► intuitive tools to visualize, drill down the problems and therefore enhance the debugging efficiency based on R&S®SmartAnlytics► the specialized key performance indicator (KPI) tests configured through real network data offered on R&S®CMX500 that guarantee the test reliability and repeatabilityThis application note aims to demonstrate the status of quo R&S®CM360° F2L solution.

This application note explains how to synchronize the signals from multiple R&S®SMBV100A vector signal generators in time.The synchronization of the instruments is based on a master-slave principle where one R&S®SMBV100A acts as master and supplies all necessary synchronization signals to the other instruments (slaves). The setup is simple and provides highly synchronized test signals. Time synchronous signals are needed in several applications. The master-slave setup is ideal for basic MIMO tests, certain GNSS test scenarios and WLAN IEEE 802.11ac non-contiguous channel generation. Furthermore, synchronous baseband signals are the basis for generating phase coherent RF signals with the R&S®SMBV100A.
