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.

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.

The need to properly represent the ever changing complexities of the RF environment across communications, surveillance, electronic support measures (ESM) and signal intelligence system (SIGINT) with the advances of signal complexity and bandwidth, requires an enormous test and measurement effort.Extensive field tests are often applied to verify the performance and capabilities under preferably natural but controlled conditions.

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. The R&S®EX-IQ-Box is a digital interface adapter that provides digital baseband I/O for Rohde & Schwarz signal generators and signal analyzers. An R&S signal analyzer with digital baseband interface R&S®FSQ-B17 can analyze digital baseband components input from the R&S®EX-IQ-Box. Data collected with a test-setup consisting of an R&S signal analyzer and the digital interface adapter R&S®EX-IQ-Box can be used in an Agilent ADS environment. For details of how to input the results to ADS, see Application Note 1MA72: 'Using R&S® Instruments within Agilent®ADS®Software'

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.

Signal generators are often used in automated test environment applications. The replacement of those instruments, e.g., due to malfunction or standard replacement procedures requires special care to be taken in consideration. Replacement of those instruments requires compabitiblity between the replacement and the replaced device in at least the electrical and remote-control features. This application note describes in detail how to use the emulation modes of the R&S® series SMA100A, SMB100A, SMF100A signal generators.

Receiver diversity improves reception quality by using multiple antennas with a preferably low correlation factor between each other. This results in a more robust handling of multipath signals, since a deep fade will then not affect all received signals at the same time. However, the compact dimensions of handheld devices can introduce unwanted correlation due to their dense antenna spacing. In this case, the popular diversity test setup consisting of several independent transmitters will no longer serve the needs of a realistic simulation, since correlation effects have to be taken into account here. A clever solution is to operate the R&S®SFU in split-fading mode in combination with a second transmitter. This can be another R&S®SFU, the R&S®SFE, the R&S®SFE100 or the R&S®SMU200A. In this way, two diversity signals of adjustable correlation for any common broadcast standard are coded in realtime, while their individual multipath profile is precisely specified by the extensive features of the R&S®SFU fader module.

DECT standard ETS 300 175-2 prescribes among others measurement of the transmit power and the unwanted power in adjacent channels. Following a brief introduction into DECT, this Application Note describes the standard-conforming measurement of the normal transmit power NTP and the unwanted adjacent-channel power ACP using a spectrum analyzer from the FSE family ( firmware version 1.63 and higher). Option FSE-B7 (Vector Signal Analyzer) is required for measuring the normal transmit power NTP since the signal must be demodulated for this measurement. Due to the wide dynamic range of FSEA20 and FSEA30, the adjacent channel power ACP can be measured without bandpass filters suppressing the transmit channel. Option FSE-B7 is not required for measuring the adjacent-channel power.
