Tektronix PQA300
PQ Analyzer
Description
The Tektronix PQA300 will analyze picture quality with repeatable, objective measurements that directly replicate subjective human visual assessments. These measurements have invaluable information for engineers who are working to optimize video compression without compromising picture quality.
The PQA300 is a generator and it is an analyzer of reference test material for testing compressed video systems. Standard inputs and outputs are 270 Mb/s serial component (Rec. 601). Option 01 will provide analog composite NTSC/PAL inputs and outputs.
