The International Electrotechnical Commission (IEC) created the MBRAI specifications, which call for strict conformance tests that ensure the proper functionality of mobile receiver terminals for DVB-T/H transmissions. MBRAI is a common abbreviation of the IEC 62002 standard and stands for “mobile and portable DVB-T/H radio access interface”. This Application Note describes how the Broadcast Test System R&S®SFU provides all functions to generate MBRAI-compliant test signals. Only two special measurements require additional sources. For this purpose, the Test Transmitter R&S®SFE100 is used.

The Society of Cable Telecommunications Engineers (SCTE) defined the ANSI/SCTE 40 specification: Digital Cable Network Interface Standard. ANSI/SCTE 40 tests are designed to test conformance of set-top boxes and other cable receiving equipment to ensure that they will operate correctly when installed in a cable system. The tests are a combination of noise (AWGN and phase noise), AM hum, micro-reflections, digital and analog adjacent channels, and other discrete interferences. These impairments are found on most cable systems to some degree. Rohde & Schwarz provides set-top box manufacturers with an easy solution to perform conformance testing in line with ANSI/SCTE 40 by using the R&S®SFU broadcast test system and the R&S®SFE100 broadcast tester. The R&S®SFU is able to perform most of the test procedures in one unit. Furthermore, additional test transmitters allow the simulation of full channel loading. This Application Note explains the specific test requirements, a possible setup, and the configuration using the R&S®SFU/SFE100.

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 are programs that quickly and conveniently convert the contents of I/Q waveform files of nearly any structure into the I/Q format used by the R&S®BTC, R&S®CLG, R&S®SLG, R&S®SFU, R&S®SFE and R&S®SFE100 signal generators. This makes it possible for the signal generators to use their integrated ARB function to generate precise RF signals from nearly any I/Q waveform file.

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 or more R&S®SFU, R&S®SFE, R&S®SFE100 or R&S®SFC can also be used. R&S®ETL or R&S®ETC are suggested to fine-tune the synchronization between the generated RF signals.

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 note describes how this type of composite T2-Base/T2-Lite RF signal can be simulated using one R&S®BTC or alternatively two instruments from the family of broadcast signal generators comprised of the R&S®SFU, R&S®SFE, R&S®SFE100 and R&S®SFC. Only one corresponding multiple profile T2-MI stream is required, either in the form of a file or via an external gateway.

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.

Spectrum that was previously reserved for TV broadcasting is being freed up in many countries for use under the new Long Term Evolution (LTE) mobile radio standard (keyword: 'digital dividend'). As a result, numerous coexistence scenarios are possible. So network operators and manufacturers from both the mobile radio and the broadcast sector have a vital interest in avoiding any interference and performing in-depth testing of their products. Rohde & Schwarz offers a wideranging product portfolio for such applications. This Application Note presents Test & Measurement equipment for the broadcast and mobile radio sector and discusses some possible test setups.
