Tektronix Picture Quality Analyzer

PQA600B Picture Quality Analyzer

The  Tektronix  PQA600B (PQA) is the latest-generation Picture Quality Analyzer built on the Emmy Award winning Tektronix PQA200/300. Based on the concepts of the human vision system, the PQA 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.

Features and Specifications of the Tektronix PQA600B includes:

• Fast, accurate, repeatable, and objective picture quality measurement (Option BAS)
• Predicts DMOS (Differential Mean Opinion Score) based on Human Vision System Model (Option BAS)
• SD/HD/3G SDI, HDMI compliant with HDCP interface 2-channel capture and 2-channel generation with Swap-channel / Side by Side / Wipe display on all video formats except 1080p 50/59/60  formats
• Real time up / down conversion at generation / capture with SDI/HDMI interface for testing the instrument with up / down conversion process
• IP interface supporting IGMP for simultaneous generation and capture
• IP Interface with simultaneous 2-channel generation / capture with IGMP support for multicast streams (Option IP)
• Picture quality measurements can be made on a variety of UHDTV1/4K formats (3840×2160, 4096×2160), HD video formats (1080p, 1080i, 720p) and SD video formats (525i or 625i) (Option BAS)
• User-configurable viewing condition and display models for reference and comparison (Option ADV)
• Attention/artifact weighted measurement (Option ADV)
