The simple network management protocol (SNMP) can be used in a wide range of applications, as described in Rohde & Schwarz Application Note 7BM65 “The Simple Network Management Protocol: Remote Controlling for Monitoring Devices“. In particular, the option of centrally managing monitoring sensors – such as the R&S DVM for RF and baseband signals in digital broadcasting – shows the potential of this technology. However, the protocol alone is not enough to achieve this management functionality. Specialized management applications are needed that carry out the SNMP requests and display the results graphically. This application note and the associated SNMP example application will show how the R&S DVM family can be used for this type of application. Rohde & Schwarz customers can use the included source code (programming language: C#) to make the modifications needed for their own situations.

Connecting simulation and measurements on physical devices

This application note is based on collaborative work between MathWorks® and Rohde & Schwarz. The focus is on linearization of a non-linear device, in our case the RF power amplifier. It is shown how simulation and the integrated functions of the Rohde & Schwarz instruments R&S®SMW200A and R&S®FSW work hand-in-hand with the simulation capabilities from MathWorks in MATLAB / Simulink. The goal is to provide a toolset to enable proper modeling and linearization approaches to optimize and verify the behavior of the power amplifier when used with complex wideband signals as used in 5G NR or latest satellite links.The application note brings code examples and an exemplary block set for MATLAB / Simulink to provide an easy start to replicate and use the described procedure.

DVB-T signal quality is determined by measuring the modulation error ratio (MER). However, a poor MER does not indicate its causes since different interference factors overlap at the transmitter when a signal is generated and transmitted. The R&S®ETL TV test receiver now has a unique new measurement capability that makes it possible to demonstrate to what extent the modulator's phase noise affects the MER.

In modern telephoning, dual-tone dialling is used more and more often. Every symbol to be transmitted is coded by two frequencies which are sent at the same time. To ensure a trouble-free call setup, transmission has to be done within defined tolerances. For measuring these kind of dialling signals, the measurement equipment has to fulfill high requirements. This application note describes how the measurements can be carried out by using the Audio Analyzers UPL or UPD. It also presents a measuring program for this application.

The voltage standing wave ratio (VSWR) is one of the parameters in RF systems that measures the impedance mismatch. Under ideal conditions, when the load is perfectly matched to the source, the VSWR will be 1. A mismatch in the system causes reflections that will increase the VSWR and lead to losses in transmission. Although most RF components are typically designed and specified with a characteristic impedance of 50 Ω , applications and system components for cable television are designed and specified with a characteristic impedance of 75 Ω . This application note describes the measurement procedure for VSWR measurements in 75 Ω systems using the R&S®FSH3-TV handheld TV analyzer.
