NI DIAdem is high-performance software purpose-built for engineers who work with complex test and measurement data. It centralizes data access, accelerates data exploration, enables advanced analysis, and automates reporting in a single environment. With tools for searching, synchronizing, visualizing, and analyzing large, time-based data sets, DIAdem helps teams turn raw test data into faster, more confident insights.

With DIAdem, you can synchronize mixed data streams such as video, vibration, and analog signals to visualize true system behavior. Engineers can identify anomalies, correlate events across sensors, and validate designs in a single environment. Compare runs, overlay channels, and investigate large data sets with ease.
The diagram shows a typical data analysis and reporting workflow with DIAdem. First, import data from multiple sources and in various file formats into DIAdem. DIAdem will then index and synchronize the data so it can be visualized simultaneously in a single environment. You can perform analysis with built-in calculations, filters, and more—then, share your work and insights using the report editor. DIAdem also contains automation tools that can complete this entire process, allowing teams to standardize and generate consistent test reports.

This capability helps engineers quickly locate and prepare the right test data across distributed systems and file formats. By organizing metadata and managing data access at scale, DIAdem eliminates manual file searches and accelerates analysis workflows.
Engineers can interactively explore time-based measurement data and quickly understand system behavior across synchronized sources. With purpose-built visualizations for test workflows, DIAdem makes it easy to compare signals, investigate events, and validate results across different files and large data sets.

DIAdem is hardware-agnostic and works with data from NI DAQ devices, third-party loggers, and standard automotive formats.
DIAdem natively reads TDMS/TDM files generated by NI software and loggers such as LabVIEW, FlexLogger, CompactRIO systems, PXI-based DAQ solutions, and custom NI applications. Engineers can load, correlate, and analyze NI-generated data without conversions or plugins.
DIAdem supports data from Dewesoft, imc, HBM, ETAS, Vector, Müller-BBM, Kistler, and hundreds of other acquisition systems through DataPlugins. Files load natively with full metadata—enabling seamless search, synchronization, and analysis.
DIAdem supports industry-standard automotive formats such as CAN, LIN, FlexRay, BLF, ASC, MDF4, and more. Engineers can align bus data with analog channels, GPS, video, vibration, and telemetry for true multidomain correlation.
Your system must meet the following requirements to use DIAdem.
x64-compatible processor, 1.6 GHz or higher
2 GB or more
Up to 6 GB free on system partition (depending on OS)
Color depth at least 16-bit, 24-bit, or 32-bit (recommended)
From 1280x800 with a scaling step of 100%
DIAdem must be installed with administrator rights; standard user accounts can run DIAdem after installation
DIAdem accelerates measurement data post-processing by organizing channels, synchronizing time-based signals, and applying reusable analysis routines. With scripting, automated templates, and mixed-format support, engineers standardize workflows, reduce variability, and convert large data sets into consistent, high-quality engineering results.
DIAdem enables teams to standardize analysis sequences and report templates that automatically adapt to new measurement data. Engineers generate consistent certification, customer, and internal reports with reduced manual effort. Automated logic and layouts eliminate variability and significantly shorten report turnaround time.
DIAdem synchronizes video, GPS, CAN, LIN, FlexRay, vibration, and analog signals to deliver a complete view of vehicle behavior. Built-in alignment automatically harmonizes timestamps and events across sources, enabling fast correlation and analysis without manual tools or custom workflows.
