Thomas Lechner 1GP117 Since June 2017 almost all radio transmitters and receivers sold or put into operation in the European Union have to be tested for immunity against interferers in adjacent frequency bands. ETSI standard EN 303 345 defines the tests to be performed on broadcast sound receivers, and the requirements to be passed. This application note describes the test procedures and provides script
Dr. Fabian Guettge 1DC02 R&S ® VISA is a standardized software library that allows fast communications over diverse interfaces with a wide variety of T&M instruments that are detected on the network from PC applications. R&S ® VISA also includes a trace tool that simultaneously monitors communications between multiple applications and T&M instruments, and permits targeted analysis with the aid of efficient
Frequency allocation plans are under discussion in the US and Europe to open the lower C band for 5G applications. This portion of the spectrum provides 5G with more bandwidth than conventional lower mobile frequency bands and is contiguous while the C band is actually in use for satellite downlinks to satellite earth stations (SES). 5G, C band, FSW, SMW200A, BTC Coexistence of 5G and satellite services

Automotive Infotainment Testing Automotive Infotainment Testing, CMW500, BTC, SMBV100A Functionality testing of automotive infotainment devices - Application Card Challenges Modern day vehicle interactivity takes place on the centrally placed touchscreen head unit display (HUD) on the car dashboard. Infotainment systems have become a central hub for a wide range of vehicular functionality. These systems

Frederic Schütze 1MA074 Versatile Software Tool for Rohde & Schwarz Instruments RSCommander is a versatile software tool for a wide range of Rohde & Schwarz spectrum-, network analyzers, signal generators and oscilloscopes. It allows for automatic instrument discovery, making screenshots, reading traces, file transfer and simple script creation. ABFS, AFQ, AFQ100A, AFQ100B, AMU, AMU200A, CBT, ESCI,
Mahmud Naseef 1GP114 Receiver diversity improves reception quality by using multiple antennas with a preferably low correlation factor between each receive path. The result is a much more robust reception, since a deep fade will not affect all received signals at the same time. However, the complex geometry and positioning constraints for antennas of the receiving devices can introduce an unwanted
Thomas Lechner, Jongmyoung Kim 1GP116 Starting from June 2017, almost all radio transmitters and receivers sold or put into operation in the European Union have to be tested for immunity against interferers in adjacent frequency bands. ETSI standard EN 303 340 defines the tests to be performed on digital television receivers and requirements to be passed. This application note describes the test procedures
Naseef 1MA275 What used to be the car radio has evolved from adding a cassette player to state of the art entertainment on the move. All this while keeping driver & passengers connected. The design challenge is to bring all the communication and broadcast standards into a small form factor that fits in the dashboard of the car. The RF modules need to support multiple standards in a single assembly
Ralph Kirchhoff 1GP111 Nearly all analog NTSC broadcasting has ended in the US, Canada and South Korea. The digital switchover to ATSC in Mexico is expected to be completed by the end of 2016. ATSC receivers must fulfill the recommendations described in “ATSC Recommended Practice: Receiver Performance Guidelines” (document A/74:2010) before they can be sold freely in the markets that have adopted the
M.Naseef, F.Ramian, Y.Shavit 1MA273 The application note address test and measurement possibilities for DVB-S2 and DVB-S2X signals in the K u & K a -band. The AN includes detailed description of measurement setups, DVB-S2 and DVB-S2X signal generation, up-conversion and signal quality (Error Vector Magnitude and Modulation Error Ratio) analysis in the K u & K a -band using Rohde & Schwarz instruments
Harald Ibl 7MH107 Despite the now standard digital distribution of video signals, analog video signals are still an integral part of AV terminals in the home. This application note covers the fundamentals of analog component signals and shows how the signal quality can be measured with the measuring equipment from Rohde & Schwarz.

Marius Schipper, Harald Ibl 7BM87 For A/V devices such as smartphones, tablet PCs, Blu-ray players, set-top boxes and TV sets, the perceived video quality must satisfy very high standards. A/V devices need to hold their own in three main areas: ı Stability (environmental influences, response to source signal disturbances, etc.) ı Performance (switching times, delays) ı Compliance with standards (input
7BM81 Version 1.3.1 of the DVB-T2 standard ETSI 302 755 introduced the T2-Lite profile to ease the implementation of mobile TV services. This was achieved by minimizing the complexity of the required receiver and allowing side-by-side integration into existing conventional (T2-Base) DVB-T2 channels. For the purposes of testing the compatibility and performance of receiver modules, this application
7BM80 This application note describes how the transmitter landscape of a DVB-T2 single-frequency network (SFN) can be simulated in multiple input single output (MISO) mode in order to test the compatibility and performance of receiver modules. Neither an external T2-MI gateway nor a GPS receiver is required - just an R&S ® BTC equipped with two RF paths. Alternatively, one R&S ® SFU coupled with one
7BM79 I/Q waveform files contain the digital complex sample values of a radio signal. They can be synthetically computer-calculated for generating precisely defined contents, or they can represent the recording of a received live signal. The structure of these files has never been standardized, which is why so many different formats are in use today. R&S ® IQ Converter and R&S ® IQ Stream Extractor
