Video signal generator from Rohde & Schwarz tests a wide variety of latest-generation TV displays
The R&S® DVSG generates standard-compliant audio and video signals on AV interfaces such as HDMI/DVI, RGB/YPbPr, SDI/HD-SDI, S-Video, SCART, D4, CCVS and RCA. It uses the generated signals to test TV displays (including beamers) in all common SD and HD formats up to 1080p. A simple import function allows users to work with their own signal templates.
The R&S® DVSG also provides signals that occur in the everyday operation of a display by the end user. For this purpose, the R&S® DVSG generates AV signals on the basis of MPEG-2 transport streams. Furthermore, live signals can easily be recorded and played, making it possible to simulate real-world situations in the lab. All tests can be performed quickly and conveniently because the AV signals are simultaneously available at different analog and digital interfaces.
Numerous test signals are available for the transport stream generator and recorder function. For example, DVB- and ATSC-specific features are supported as well as MPEG 2 and MPEG-4/H.264/AVC coding. The MPEG-2 transport stream generator and recorder function makes it possible to test multiplexers, decoders and all other components used to process transport streams. Together with a modulator such as the R&S® SFE or R&S® SFE100, the R&S® DVSG forms a compact and powerful system for testing set-top boxes.
Its compact design and low weight make the R&S® DVSG very portable and its integrated display makes it easy to operate. Signal files can be exchanged via a USB interface or a network connection. Owing to the instrument’s high memory capacity, even very extensive signal libraries are quickly available.
Besides being ideal for developing and producing TV displays, the R&S® DVSG is ideally suited for service applications and for test houses. Its SDI/HD-SDI output option allows the instrument to be used for professional studio applications.
