QMSIP/DVB/MPEG-2Quality Monitoring System
2QMS - Quality Monitoring System
Complete and flexible solution for monitoring of DVB based transmission systems
Product family with 3 different models and several options
Main functions:• Automatic carrier scanning function (in DVB-S/S2 version)• Physical layer measurement (signal level, bit error rates, quality of
reception)• In-depth ETR101290 analysis of Transport Stream• IP data decapsulation and IP flow monitoring• Flexible and customizable
report generator on allmeasured values
Introduction
3QMS - Quality Monitoring System
Automatic frequency scan on a given orbital position
List of downlink frequencies with symbol rates and error correction rates (FEC rates)
Definition of parameters (minimum/maximum symbol, frequency range) possible
Analysis results are fedinto a report generator
Scanning Function (DVB-S/S2 version)
