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.

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.
