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.

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 and output formats)Any deviations from the expected video and audio output can be automatically and precisely detected with R&S A/V distortion analysis on all common analog and digital interfaces such as HDMI™ and MHL™.This document examines the relevant setups and configurations.

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).

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 and multiple modules are placed next to each other. The frequencies defined by the RF standards are in very close proximity and hence need to co-exist with each other. Moreover, the antennas inside the car are subjected to cross-coupling effects with mobile devices of passengers. To ensure the RF performance of the infotainment system, all of these scenarios need to be thoroughly tested.This application note highlights some of the RF measurement challenges and introduces Rohde & Schwarz equipment required for relevant RF characterization of car infotainment devices.

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.

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.
