R&S®DVQ Digital Video Quality Analyzer
Always in the picture about picture quality
Operation
DVQ can be controlled manually via the keypad with fast-access keys for the main menus and softkeys for the submenus. The displayed contents of the clearly arranged LCD is inserted into the decoded picture at the video output. With a recorder connected the quality ratings can be logged together with the associated picture contents.
Remote control
DVQ features full remote-control capability via the RS232 or Ethernet interface using the same commands in SCPI language. When using the Ethernet interface, the TCP/IP and SNMP protocols are available.
DVQ has a built-in 32 Mbit memory for transport stream data. Depending on the data rate of the video stream, the memory is sufficient for storing a video data sequence of approx. 5 to 10 seconds. The sequence can be read out for in-depth analysis via one of the remote-control interfaces using for instance the Quality Explorer™.
