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.

The high-definition multimedia interface (HDMI™) is used to transmit audio and video data. HDMI has become the standard for a variety of consumer electronic products, such as Blu-ray™ players, A/V receivers, set-top box, TV monitors and digital video/ still cameras. The HDMI interface measurements needed for these products require specialized T&M equipment. This equipment is not only needed for certification, but is also used for a variety of tests during development, for quality assurance and for end-of-line production testing. The R&S®VTC, R&S®VTE and R&S®VTS video testers from Rohde & Schwarz make it possible to test A/V interfaces such as HDMI easily, reliably and cost efficiently. This application note focuses on functional testing and debugging of HDMI interfaces using the R&S®VTC/VTE/VTS. It explains how these instruments can be used to assess the HDCP implementation, the ARC or the CEC functionality.

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.

A major US East Coast broadcast network was looking for a solution that would enable them to orchestrate multiple business units to handle the increased demand to deliver content with a very fast turnaround.
