Unlock new insights in ECU development with innovative analysis solutions

ETAS Measure data analyzer offers support for different measurement file formats. This includes all MDF versions since MDF V2. You can obtain best results with files following the ASAM standardized MDF V4.x format, including indexing and compression.

Additionally, MDA supports customer-specific textual ASCII-based measurement file formats by means of an interface and a simple INI format specification.

Users can extract selected signals and time periods from original data into new measurement files. Conversion between all supported file formats is also possible.

CAN bus trace files in BLF, ASCII or MDF format can be loaded and analyzed as well by using an add-on.

Several 'instruments' allow the visualization of measurement data in different ways, for example:

• In an 'Oscilloscope', signal values can be displayed as curves over time.
• A ‘Scatter Plot’ instrument helps identify signal relations.
• For a detailed view on individual samples a ‘Table’ instrument and an ‘Event List’ can be used.
• The ‘Statistics’ instrument reveals characteristics like minimum, maximum, average, standard deviation, etc. for a definable time range.
• Bar chart views allow to compare the absolute or relative values of many signals at one specific point in time.
• In a GPS map, tracks can be displayed combined with color coding for a third signal.

By arranging the instruments onto layers, users can easily keep the screen clear and manageable, even in case of complex configurations.

To use the available screen space most efficiently, supporting functionality is split into docking windows.

• This includes an overview of all currently used configurations and files in the 'File Explorer'.
• The 'Variable Explorer' allows to search and filter signals from loaded measurement files. Even from 100,000s of signals, the desired ones can be found and selected quickly.
• The 'Configuration Manager' offers a hierarchical overview of the complete configuration contents. It allows easy management of layers and instruments.
• The 'Information Window' shows meta information for measurement files or signals. It also allows to add comments to configurations and layers.
• The behavior and appearance of instruments, axes, etc., can be defined in a 'Properties' docking window.
• Via 'Calculations' it is possible to derive relevant details from measured signals. Both the free definition of a calculated signal's formula and the usage of predefined functions (e.g. based on FMU files) enable the definition of virtual signals. This can be used additionally to the recorded ones.

Users can position all docking windows as desired. By hiding the ones not needed, they can use the valuable screen space to create a bigger view of the displayed data.

Using MDA in combination with other ETAS software products is very easy:

• From INCA, a simply click on an icon starts MDA. The last recorded measurement data is opened automatically and can be analyzed, even if the recording is still running in INCA.
• You need more details about a specific ECU signal, its meaning and relation to other ECU variables? Just trigger the EHANDBOOK NAVIGATOR from MDA to get access to the unique interactive documentation format.
• You are using ETAS EATB application for an automated reporting, but some details require a deeper look into the data? EATB can create a configuration file which can be imported into the MDA to directly jump to the signals and point in time which require your attention.
• ETAS DATA OPERATOR offers a UI to pre-process measurement data so that the usage in MDA is simpler. Measure data analyzer is available as stand-alone installation as well as in combination with the INCA product.

Together with Measure data analyzer you additionally receive several useful tools:

• With Mdf Shell extension, some additional MDF-related meta information can be shown in Windows Explorer, like experimentor and recording details. This facilitates identification and selection of measurement files.
• MdfConvert.exe is a command line tool to extract subsets of signals and specific time ranges from an existing file into a new file of any supported format.
• MdfCombine.exe is a command line tool to turn a series of comparable MDF recordings into one combined MDF file.
