ETAS MDA V8 - Defining a Time Offset for a Measure File

4 Configuration Creation | 37
On the left side of the dialog you can see the list of the ECU and device com-
binations of the new measure file, on the right side the combinations of the used
signals from the old file.
To map the devices, do the following:
1. Drag from the Devices from replacement filecolumn an entry and drop it
in the Mapped devices column of the desired target row.
2. Click OK.
If "No-Match" signals remain after the mapping, you can assign the signals manu-
ally (see "To replace a signal" on page101) or delete them (see "To delete all "No-
Match" signals" on the previous page).
4.2.2 Defining a Time Offset for a Measure File
Working with several measure files usually requires to align the time line of the dif-
ferent files such that the actual data can be compared.
To see how you can align the timebase of different measure files or apply a time
offset to individual signals, watch our video Using the Time Offset.
You can perform the following actions:
"To apply a time offset by shifting a signal curve" below
"To apply a time offset in the Time Offset window" below
To apply a time offset by shifting a signal curve
1. In the oscilloscope, select the signal that you want to shift. You can define
later whether it is a representative for a file or it shall be shifted individually.
2. Press SHIFT and drag the signal curve to the desired position.
3. Confirm one of the following options:
l
Apply Offset to File
The time offset is applied to the whole measure file, i. e. it affects all sig-
nals of the file. The numerical offset value is displayed in the Time Offset
window.
l
Apply Offset to Signal
For the shifted signal, a calculated signal will be created, which gets the
shift applied as time offset in the Output Options of the Calculated Sig-
nal window. Subsequently, the calculated signal with the time offset will
be used to replace the input signal everywhere in the configuration, i.e.
in all instruments and when it is used as input of a calculated signal.
Note that for a calculated signal the individual time offset and the file time
offset of its input signal(s) are cumulated.
To apply a time offset in the Time Offset window
1. In the Time Offset window, the available measure files with their identifiers
are listed. Enter the required time shift in seconds for the respective file.
Positive or negative values as well as decimals are allowed.
