The manual covers the setup, operation, and troubleshooting of a DTV monitoring system using instruments like the DVQM, DVMD/DVRM, and DVRG, which are designed for monitoring digital TV transmission systems and analyzing transport streams for quality and errors. It provides details on configuring the Multichannel Digital Video Quality Analyzer DVQM, remote control via Ethernet, and integrating additional devices like DVRM/DVMD and DVRG for comprehensive monitoring and recording of transport streams.
Manual Overview
The manual for the DTV Monitoring System by Rohde & Schwarz outlines the setup and operation of a system comprising the DVQM, DVMD/DVRM, and DVRG instruments. The DVQM is designed for monitoring multiple programs across various transport streams and can be configured to customer specifications, including the installation of video quality analysis options and IP address settings. Each analyzer board within the DVQM operates independently and is controlled via an external PC connected through Ethernet, allowing for remote configuration and fault detection. The system supports integration into custom monitoring setups using SNMP, and remote control is facilitated through SCPI commands. For transport stream analysis, the DVMD/DVRM can be added to monitor individual streams, while the DVRG records specific sections of the stream triggered by faults, enabling detailed post-event analysis. The manual emphasizes the importance of setting the correct IP address for network operations, which can be adjusted via the RS-232 interface if necessary.
Quick Issues Covered
- Diagnose transport stream errors with DVMD/DVRM analysis tools.
- Remote control DVQM via Ethernet for measurement results and fault detection.
- Configure DVQM IP address using RS-232 and IP-SNMP Config.
Overview
