PQA500 Picture Quality Analyzer
The PQA500 is the latest-generation Picture Quality Analyzer built on Tektronix’ Emmy Award winning PQA200/300. Based on the concepts of the human vision system, the PQA500 provides a suite of repeatable, objective quality measurements that closely correspond with subjective human visual assessment. These measurements provide valuable information to engineers working to optimize video compression and recovery, and maintaining a level of common carrier and distribution transmission service to clients and viewers.
