TDM File – What is .tdm file and how to open it?

TDM File: Format and Usage

A TDM file stores binary measurement data acquired using National Instruments’ LabVIEW software. It is a compact and efficient format designed specifically for large datasets, enabling fast data access and analysis. TDM files contain multiple channels of data, each with its own metadata, including channel name, data type, and sampling rate. The binary format allows for quick loading and efficient processing of large amounts of measurement data.

TDM files also support annotations, which can be embedded within the file to provide additional information about the measurement data. These annotations can include text, timestamps, and other metadata, allowing users to easily identify and interpret the data. The flexible structure of TDM files makes them suitable for use in various applications, including data logging, analysis, and visualization. National Instruments provides a range of software tools that support the reading, writing, and manipulation of TDM files, making it easy to integrate them into custom applications.

Open TDM File on Windows

• Using National Instruments Applications: If you have National Instruments software installed, such as LabVIEW or Measurement & Automation Explorer (MAX), you can open the TDM file directly within these applications. In LabVIEW, navigate to “File” > “Open” and select the TDM file. In MAX, expand “My System” in the navigation pane, right-click “Data,” and choose “Open” > “TDM File.”

• Using Third-Party Software: Several third-party software programs can open and view TDM files. One popular option is TDMSpy, a freeware utility specifically designed for working with TDM data. To open a TDM file in TDMSpy, drag and drop the file onto the main window or use the “File” > “Open” menu.

Open TDM File on Mac

• Using Third-Party Software: Mac users can open TDM files using third-party software such as LabVIEW Run-Time Engine (RTE). To install RTE, download the Mac installer file from the National Instruments website and follow the on-screen instructions. Once RTE is installed, you can open TDM files by double-clicking them or dragging and dropping them onto the RTE application icon.

• Using Wine: Wine is a compatibility layer that allows Windows applications to run on Mac. You can install Wine on your Mac using a package manager like Homebrew, then use Wine to launch third-party Windows software that supports TDM files. Please note that Wine is not officially supported by National Instruments, and compatibility may vary depending on the software you use.

TDM File Format

The TDM file format, short for LabVIEW Binary Measurement File, is a proprietary binary data format developed by National Instruments. It is designed to store data acquired from measurement and test applications using the LabVIEW software platform. TDM files can contain various types of measurement data, including time-stamped scalar values, waveforms, and images. The data is organized into channels, which represent individual measurement signals or sources. Each channel contains metadata such as channel name, measurement units, and sampling rate.

Advantages of TDM Files

TDM files offer several advantages for storing measurement data. Firstly, they are efficient and compact compared to text-based data formats. The binary format reduces file size while maintaining data integrity. Secondly, TDM files are self-describing, meaning they contain all necessary metadata within the file itself. This simplifies data interpretation and eliminates the need for separate configuration files. Additionally, TDM files support advanced data structures such as hierarchical measurements and nested data sets, making them suitable for storing complex measurement scenarios.
