An operator of a network of terrestrial transmitter stations wants to have the most cost-effective means of monitoring the network's numerous transmitter sites from a main monitoring center. Modern error sensors such as the R&S DVM50/100 and the R&S ETX-T are used for diverse monitoring functions at the individual transmitter sites as well as to transmit monitoring status to the main monitoring center. These error sensors have a function-rich SNMP agent designed specifically for this purpose. Simple network management protocol (SNMP). Despite the 'simple' in the protocol name, some users are still afraid to use it for remote control and monitoring. This Application Note therefore provides a user-friendly and practical look at, for example, how the monitoring functions via SNMP can be used for the R&S DVM. The following sections provide a brief look at the SNMP protocol, the R&S DVM/ETX implementation, and useful tools for working with SNMP. A description of how SNMP can be linked to various development environments (C++, C#, Java) is also provided.

While RF communication signal distortions in nonlinear transmission paths have been predicted theoretically and studied experimentally for various signals, it is interesting to examine a wideband nonlinear system reaction to a wideband 3G signal and a narrowband 2G signal. Research and testing have demonstrated that, while most vital signal parameters remain within the limits specified by applicable standards even if composite signal power approaches specified maximum power, a relatively high level of spurious emissions caused by cross- and intermodulation can result. To avoid degrading both existing and new systems, this and other signal quality issues must be considered when designing and deploying multitechnology systems.

The FLO in MediaFLO stands for 'forward link only'. MediaFLO technology covers transmission of files and multimedia content to handheld devices. The FLO device minimum performance specification (MPS) was created to ensure that FLO receivers can receive a FLO service that fulfils the compatibility guidelines of the FLO air interface specification. This Application Note shows how the Broadcast Test System R&S SFU from Rohde & Schwarz can be used to generate all test scenarios required by the minimum performance specification.

The fact that cable TV networks are generally located in densely populated areas or extend over large geographical regions makes the presence of line extenders at regular intervals a necessity. Cascading large numbers of amplifiers however calls for excellent noise, SWR and intermodulation distortion specifications for the integrated amplifiers in order to avoid quality of service dropping below minimum acceptable levels. Composite second order, composite triple beat & cross modulation are commonly used figures to specify the performance of CATV equipment. In this application note we describe how to determine these figures with the aid of R&S SMU200A or AFQ100A and SMV vector signal generators.

This document presents a simple procedure for network analysis that is more cost-effective than the use of scalar network analyzers. It allows the accurate measurement of the transmission characteristics of filters, amplifiers and frequency converters over a large frequency and dynamic range. In order to reach very high measurement speeds, Rohde & Schwarz signal generators are operated in 'List Mode', and Rohde & Schwarz power meters are operated in 'Buffered Mode.' The required programming for the signal generator and the power meter is illustrated by excerpts from a Visual Basic program which is available, free of charge, upon request.
