The Measurement Decoder R&S DVMD belongs to MPEG-2 and DVB or ATSC like a waveform monitor to the analog world. It provides everything that is required for reliably handling the new technology. With its special features no error goes unnoticed. And all this is in an easy-tooperate and portable unit .
◆ 25 DVB or 18 ATSC realtime measurements at a time
◆ Analyzer and decoder in one unit
◆ Analysis of data rates
◆ Trigger-on-error function
◆ Integrated long-term report
◆ On-screen display on video monitor
◆ Measurement capabilities for all levels/resolutions (SDTV and HDTV)
The R&S DVMD analyzes and monitors MPEG-2 transport streams both to DVB and ATSC standards. PC Software Stream Explorer™ is available as an option for in-depth analysis
down to bit level, for convenient remote control of the R&S DVMD, and for integration of the R&S DVMD into networked monitoring systems.
