Introducing WinDaq™ Web Viewer: The Next Evolution of Waveform Analysis

For decades, the WinDaq Waveform Browser (WWB) playback software has been the industry standard for reviewing and analyzing acquired waveform data. Known for its disk streaming design, the classic WWB allows data files of unlimited length to be plotted on a computer display with lightning speed. However, as engineering teams become more agile and device ecosystems diversify, the need for a cross-platform, zero-footprint tool has never been greater.

Enter the WinDaq™ Web Viewer—a revolutionary, high-performance web application that brings the raw speed and reliability of the classic desktop WWB directly to your internet browser. a no-programming, point-and-click user interface.

100% Secure and Local: "Web-based" does not mean "cloud-uploaded." Your data never leaves your computer. The application accesses the file strictly on your local hard drive, ensuring total data privacy, offline capability, and compliance with strict IT security protocols.

Hardware-Accelerated Rendering: While traditional web charts choke on large datasets, the WinDaq Web Viewer leverages an ultra-fast engine. It renders millions of multi-channel data points smoothly, matching the high-speed panning and zooming engineers expect from native desktop software.

Intelligent Metadata & Event Tracking: Just like the classic WWB, the WinDaq Web Viewer automatically extracts channel metadata and applies y=mx+b scaling to display your data in meaningful engineering units . It also flawlessly extracts your channel annotations, units, and trailing event markers (including precise timestamps and user comments), featuring a dropdown menu that allows you to jump instantly to critical moments in your data.
