Vector Network Analyzers of the ZVR family measure magnitude and phase of complex S-parameters of a device under test (DUT) in the frequency domain. Using an inverse Fourier transform, the results can be transformed to the time domain. The impulse or step response of the DUT is obtained, which gives an especially clear representation of its characteristics. For instance, faults in cables can be directly localized. Moreover, special time domain filters, so-called gates, can be used to suppress unwanted signal components such as multireflections.

Using a Vector Network Analyzer from the ZVR family, not only magnitude and phase can be measured, but also group delay and even phase delay. Whereas phase delay measurements produce the highest accuracy for the electrical length of non-dispersive devices under test, such as coaxial cables, group delay measurements also give a detailed insight into the frequency dependent delay characteristics of dispersive devices, such as filters. In addition to the traditional step aperture technique, Vector Network Analyzers from the ZVR family offer a frequency aperture technique, which allows a well defined and constant aperture for group delay measurements also for a nonlinear frequency sweep.

While Mobile phones are allowed to require approximately 3 time slots for switching from transmission to reception, base stations must be able to transmit and receive at a new frequency in every time slot in the frequency hopping mode. This behaviour must of course be tested and measurements carried out on the base station transmitter and receiver. Since there is no signal generator which is able to settle at different frequencies from one to the next time slot with GSM modulation, a solution to this problem was found by linking two Signal Generators SME in such a way that they alternately provide signals at different frequencies.

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.
