The R&S®TSStream multi-TS streaming software streams a number of MPEG transport stream files simultaneously over a single IP interface. The individual transport streams result in a high overall bit rate. To make the streams available on a standard PC, the R&S®TSStream software does not play the transport stream files directly from the hard disk but first loads them into the RAM. The maximum number and length of the transport streams depends solely on the PC's available RAM.

Unattended observation of spectrum occupancy for finding spurious emissions or seldom-occuring interferers is a common task for spectrum analyzers. Sometimes spectrum data has to be monitored over quite a long period of time. TraceRecorder, a small, free-of-charge software tool for storing measurement data from Rohde & Schwarz spectrum analyzers helps you to perform this measurement task. Running on a PC, it connects to the spectrum analyzer via a LAN interface. For stand alone operation, it is possible to run it directly on a spectrum analyzer, eliminating the need for an additonal computer during data acquisition.

Your measurement task: To analyze an RF module via its digital interface. This Application Note explains how. As interfaces between the baseband and the RF modules of mobile radio base stations and terminals are increasingly digital, instruments for testing such modules need digital baseband interfaces as well.

This application note describes different measurement techniques and methods for an automotive lighting module based on a hybrid controller design. Of course, a lighting module in such an environment has to fulfil requirements according to the automotive standard, which is typically a relatively high-level standard compare to the industry standard. The oscilloscope is a perfect tool for this application to verify the set of requirements because time domain signals (analog and digital) are present in the whole design. Furthermore, measurements in the frequency domain have to be performed, which a modern oscilloscope can fulfil. In addition to the oscilloscope, a programmable power supply supports the measurement in several measurements. The set of requirements are the main reason why a hybrid controller from Microchip is a great choice for this design because it provides tremendous analogue and digital capabilities. The hybrid controller provides beside the analogue functions like an operational amplifier digital functions like analog-to-digital converter and interface functions like UART, CAN or LIN to interact with other systems. The programmable software part is hosted in the digital part. The digital part of the controller implements the communication interface and provides status information to the outer system controller. The light source itself has to avoid any flicker and shall be capable to dim to different lighting levels. Wide input voltage variations and efficiency have to be taken into account during the design of a converter dedicated for automotive applications. Nevertheless, the measurement considerations presented with the design are valid and applicable in other professional lighting industries as well.Thanks to Mr. Andreas Reiter and Mr. Milan Marjanovic from Microchip who provided us with hardware and software and their great expertise to create this application note.

Measuring the spurious emissions of transmitters used in GSM, DCS 1800 and PCS 1900 networks requires highly complex test setups since con-ventional spectrum analyzers do not have the necessary dynamic range. To obtain this range, notch filters are used to suppress the useful sig-nal. The spectrum analyzers of the FSE family make it possible for the first time to verify com-pliance with stipulated limit values for spurious emissions within the transmission band and out-side the reception band without the use of notch filters. The measurement problem and its solution by means of FSE are described in the following by way of the example of a GSM base station.

For optimization of mobile communication networks, drive tests with coverage measurement systems are being performed. The coverage measurement platform provided by Rohde & Schwarz is based on R&S® ROMES, which is the application software to define and setup measurement devices, acquire and store the measurement data and displaying measured data during the measurement period and a later replay. Additional drivers are used for attaching different measurement devices, such as the Rohde & Schwarz Universal Radio Network Analyzers TSMQ or TSMW or test mobiles from different manufacturers. Depending on the required measurement tasks, R&S® ROMES can be configured freely to adapt to the user’s needs. As long as the measurements are performed in an outdoor environment using a vehicle traveling around, size and weight of the measurement system is not a problem. As more and more measurements are performed in an indoor environment by walking around, size, weight and mechanical handling is an issue of interest. ROMES® can be used in a light weight configuration, which is small enough to be carried in a back pack. For use of R&S® ROMES with R&S® TSMW in an indoor environment, the Backpack System R&S® TSMW-Z3 has been designed. The system includes a mini PC with R&S® ROMES which needs to be controlled remotely. This application note describes, how to establish a Wireless Lan Access Point on the R&S® ROMES PC and to setup a wireless LAN connection between an Apple iPad® and the mini PC.
