This application note provides a brief introduction into the capabilities of the Rohde & Schwarz Vector Signal Generators (VSG) to create user defined digitally modulated signals called Custom Digital Modulation (CDM). Additionally an in depth description of the functions and the operation of the CDM-Toolbox is provided. The CDM-Toolbox is application software which allows an easy remote configuration of CDM signals on Rohde & Schwarz VSGs but also the creation of data list and control list files which are most useful to further extend the application area of CDM signals.

During the design process of chipsets or modules, FPGA-based hardware emulators are utilized to perform early tests with real test and measurement instruments. These hardware emulators usually run at artificially reduced speed, but apart from that function like the finished design. In this application note we explain how to test FPGA-based hardware emulators using Rohde & Schwarz vector signal generators for creating suitable real-time test signals at reduced sample rates. We further explain how to correctly adapt AWGN signal generation and fading simulation for “slow I/Q”.

Rohde & Schwarz instruments can be shared when users wish to use the same instrument. This can be done quite easily with the LAN interface, which comes as a standard option. Through this interface, Rohde & Schwarz instruments can be connected directly to a network, and users with access to the network can manually operate the instrument from a remote computer. This Application Note lists all instruments that support these features and describes the steps necessary to set up and configure the network connection to operate these instruments remotely.

Due to today’s worldwide highly competitive communications market, achieving shorter product design cycles, quicker response to customer requests and high-volume product runs at low costs is vital for manufacturers of wireless devices and components. These requirements inevitably lead to demands for improving the throughput of Automated Test Equipment (ATE) by increasing its speed. This application note describes in detail how the special features of the R&S® SMATE200A can be used to optimize speed and throughput in an automated test environment.

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.

Rohde & Schwarz signal generators can be connected in various ways to system controllers (typically PCs) and external PC peripherals. Although most of these connection operations are also explained in the instrument manuals, it is not always easy to maintain an overview. Operating manuals commonly focus on explaining a dedicated feature of a single instrument. This application note examines a range of typical user tasks and how to solve them with the different instruments.
