Analyze Smarter. Collaborate Faster.
VISION - MDF4 Viewer
VISION Data Analyzer (VDA) is a software application for viewing and analyzing measurement data in the industry-standard ASAM MDF4 format. It is built for engineers who need a clear and reliable way to work with large and complex datasets.
Designed as a 64-bit application, VDA handles large data files with stability and performance that older tools often struggle to maintain. It provides a single environment for exploring data, comparing recordings, and working through analysis without switching between multiple tools.
Now available as a standalone product, VDA no longer requires the ATI’s VISION software. This gives teams more flexibility in how they deploy and use the software across different workflows.
VDA fits naturally into existing engineering environments, whether working with ATI systems or other MDF4 data sources, helping teams move from data to insight with less friction.
Features:
- Native MDF4 Support - Open and analyze ASAM MDF4 files, including third-party data
- Multi-Recording Analysis - Compare multiple datasets side by side to spot differences and trends quickly
- CAN/LIN Data & GPS Visualizer - No separate tools required
- Flexible Visualization - Use graphs, tables, and layouts to view Message Log display in a way that fits your workflow
- Calculated Channels - Create derived signals using formulas and scripting capabilities
- Performance for Large Datasets - 64-bit design supports smooth handling of large and complex files
- Import and Export Options - Import ASCII and REC files and export full or partial datasets with thousands of signals
What’s New in VDA 4.1
Why VDA
VDA brings together data visualization, signal analysis, and data processing into a single application. Engineers can work with signal data, bus data, and multiple recordings without relying on separate tools.
- Native MDF4 support with no file conversion required
- Signal data, CAN/LIN data, and visualization in one environment
- Integration with ATI VISION data acquisition systems
- GPS data visualization with synchronized signal alignment for location-based analysis
- Designed to support both individual workflows and future centralized data management

Software PC Requirements
VISION Data Analyzer 4.0 and Beyond
Any modern PC with a supported Windows operating system has the capability to run VISION Data Analyzer (VDA). However, the user experience will vary based on the performance of the PC. Whether a particular PC configuration will provide acceptable performance with VDA depends on how VDA is used at your company. The best approach when selecting a PC to run VDA would be to obtain a sample of a potential PC and test it under real-world conditions
| Minimum Requirements | ATI Recommendations |
| Operating System | 64-bit operating system required: Windows 10, Windows 11 Windows Server: 2008 R2 – 2022 | ATI recommends a Windows operating system that is currently supported by Microsoft. |
| RAM | VDA should run with the minimum amount of RAM required by the version of Windows being used | For best performance, ATI recommends as much RAM as practical for your budget. More RAM will generally result in a better user experience when running VDA. |
| Processor | VDA should run with any processor supported by the version of Windows being used. | For best performance, ATI recommends the highest performance processor that your budget allows. VDA should run with any processor supported by the version of Windows operating system being used. However, higher-performance processors will offer a better user experience when running VDA. |
| Storage | Approximately 2 GB for VDA installation. | For best performance, ATI recommends a solid-state drive (SSD). You’ll also need additional free space to accommodate the way VDA is used at your company. For example, if VDA usage at your company involves the use or storage of large files (such as recorded data files) then you’ll need enough free space to accommodate that. |
| Graphics | No special requirements | For best performance, ATI recommends selecting higher performance graphics card hardware when possible. Although VDA has no special requirements for graphics card hardware, higher performance graphics cards can provide a better user experience for operations such as displaying live data or analyzing recorded data. |
Flexible Subscription Licensing
VDA is a software product that uses a subscription-based licensing model designed to meet the needs of modern engineering teams.
