The Rohde & Schwarz DVG MPEG2 Measurement Generator produces MPEG2 transport streams for testing digital television systems, modulators, remultiplexers, and decoders throughout development, production, quality assurance, and field service. It functions as a substitution signal source in cable headends and broadcast distribution networks, enabling decoder alignment and TV receiver validation when live program feeds are unavailable.
– Technical Specifications
• MPEG2 transport stream generation compliant with ATSC and DVB standards
• Adjustable output data rate to match transmission link and device-under-test specifications
• Programmable packet identifiers (PIDs) for flexible elementary stream routing
• Continuous time-code updating (PCR, PTS, DTS, TDT, STT) during playback—no stream restart required
• Built-in Program Clock Reference (PCR) jitter generator for decoder PLL stress testing
• RAM-based signal storage enabling wear-free, indefinite repetition
• External clock synchronization input for generator output alignment
• RS232 remote control interface
• PCMCIA interface for transport stream exchange via removable storage
• Optional SMPTE 310 interface via DV-B310 module
• Dimensions: 434 mm × 43 mm × 460 mm
• Weight: 5 kg
• Model: DVG (Type 2068.8600.03)
– Key Features
• Large library of pre-loaded MPEG2 sequences: video, audio, and data combinations with moving pictures and stationary test patterns
• Support for Rohde & Schwarz proprietary GTS format for user-defined transport streams
• Mandatory ATSC/DVB system and service tables included
• Optional Stream Combiner™ (ASC) software allows elementary stream configuration, custom stream combination, and remote instrument control via parallel printer port or USB interface dongle
– Typical Applications
• DTV modulator and decoder validation
• Transport stream remultiplexing equipment testing
• Cable headend program substitution and backup
• Broadcast receiver alignment and performance measurement
• Production and quality control test signal generation
– Compatibility & Integration
The DVG integrates into test benches via RS232 control and PCMCIA media interchange. Clock input accommodates master clock signals from external modulators or distribution equipment. Stream Combiner software extends functionality for custom multiplex configurations and multi-instrument automation.
