DSA03 Portable Stream Analyzer

DSA03 Portable Stream Analyzer is an ideal tool for MPEG-2/DVB TS analysis and record. It can conduct real-time analysis, record and detailed offline analysis on MPEG-2/DVB transport stream, and fulfill the testing tasks in a rapid way; it provides several kinds of analysis modules which will conduct detailed testing on TS parameters, monitor the PSI/SI table information in the bit stream, and help users have an in-depth understanding about whether the parameters are in conformity with the MPEG-2/DVB standards,whether the bit stream is correct, and whether the bit stream can be decoded appropriately by the receiver terminals.It can be applied in the following fields:

• Research and development of digital TV equipment, such as the development and debugging of encoders, multiplexers, modulators,etc.;
• Installation and commissioning of digital TV system, analysis, verification and fault positioning of the system;
• Operation and maintenance of digital TV system, monitoring and detailed real-time analysis on the main nodes of the system for quick fault detection and positioning, to ensure normal operation of the system;
• Upgrade of digital TV system, during which carry out real-time analysis and monitoring on all nodes of the system to ensure normal upgrade of the system.
