The PQA500 from Tektronix is an image quality analysis system that provides fast, accurate, repeatable objective measurements for video formats such as HD…
The PQA500 image‑quality analysis system offers objective measurements based on a human‑visual‑model, supporting DMOS, PSNR, attention‑model weighting and artifact detection. It can evaluate video quality across a range of formats (HD 1080i/720p, SD 525/625, CIF) and resolutions, and includes automatic spatial and temporal calibration.
The instrument provides a configurable user interface with measurement and viewing modes, supports optional SD/HD‑SDI interfaces, and outputs results as data lists, maps, or video‑replay bar graphs. It also logs errors and alarms to aid fault tracing, and can be driven by XML scripts for automated regression testing. This manual is written in Chinese.
