DVA320QC Quality Video Analyser Features:

Tests composite and component serial digital video signals in both 525 and 625 line formats.

Provides a PC based unit that allows unattended signal monitoring and automatically logs errors onto a hardcopy report for analysis. User definable good/bad thresholds and instant notification of error occurrence with exclusive alarm function.

Continuous real-time, online measurements of all key parameters including: serial jitter, color levels, EDH errors, bit activity, signal amplitude, parity bit errors, TRS errors, reserved code errors, and non-recommended value errors.

You get a simple touch screen interface with automatic indicators for illegal areas on external monitor. It provides accurate information to the end user to make necessary corrections and eliminates chances of user errors or interpretations.

Digital signal monitoring for analog video level excursions of RGB or NTSC color space, plus tests for errors in the digital transport layer - such as jitter amplitude and data formatting.
