Curve
A curve is the graphical representation of two physical quantities.
The curve is displayed as a line in a two-dimensional orthogonal
coordinate system.
D
DAT file
This file is a binary file format for measurement data (MDF). This
format is used to store, exchange and analyze measure data for
automotive system development purposes. MDF files contain so-
called meta-information like user, company, project, file comments
etc. Typically for MDF format version V3.x the file extension *.dat is
used. For MDF format version V4.x, the file extensions *.mdf or *.mf4
are used.
Data representation
Physical, binary or hexadecimal representation of a signal.
Discrete signal
As opposed to analog signal: a signal for which only a defined num-
ber of specific values is possible.
Display Name Rules
View used for creating and maintaining rules for shorten long vari-
able names.
DXL file
DXL stands for a textual measure file format. It contains only real
data, i.e. only data that has actually been recorded, and no inter-
polated data.
E
Endpoint
Point by which the shape of a bound in the scatter plot is defined.
Enumeration
Data type which is based on a verbal conversion formula (i.e. certain
value ranges are mapped to certain output strings).
Event
A point in time at which a change or a specific situation happened.
Events can be recorded in a measure file (e.g. a pause event, a com-
ment event, a calibration activity, etc.), or are detected during ana-
lysis phase by defining a condition which turns true or false.
