The R&S®BTC broadcast test center generates DVB-C2 signals for receiver tests with a variety of simulated interference types. The selection tests stipulated by the DVB Project require a cable TV network with full channel load. Combining the R&S®BTC broadcast test center and the R&S®CLG cable load generator makes it quick and easy to create a flexible cable TV network with full channel load and to simulate all types of realistic interference, permitting tests in accordance with DVB.

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 and provides save-recall files and interferer signals for the Broadcast Test Center R&S®BTC.

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 files and interferer signals for the Broadcast Test Center R&S®BTC.

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.

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 standard. In addition, Recommendation ITU-R BT.2036-1 (07/2016), titled “Characteristics of a reference receiving system for frequency planning of digital terrestrial television systems”, includes the planning factors for an ATSC reception system, with a reference to ATSC Recommended Practice A/74:2010, because operation is in a more dynamic environment.

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.

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).

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 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 correlation between channels. The popular diversity test setup consisting of several independent transmitters does not serve the needs of a realistic simulation, because radio channel correlation is not simulated.This application note explains a compact and versatile MIMO test solution for any common broadcast standard with real time fading including the simulation of channel correlation for a 1x4 MIMO system.The test setup allows very precisely specified individual multipath profiles.
