Operation with ISD Toolbox
5.7.3.3 Trace Signals
The Scope sub-tool reflects the tracing functionality of the
devices and supports tracing up to 8 signals at the same
time. The channels are shown at the bottom of the Scope
window and can be configured, enabled, or disabled. Each
channel is represented by a signal chooser numbered 1–8.
Illustration 5.28 shows a trace with 3 enabled channels (1–
3) and 5 disabled channels (4–8).
For online devices, the list of available signals and their
definitions is automatically obtained by the ISD Toolbox
from the respective device. For offline devices, the list
included in the ISD Toolbox configuration is used.
The Scope sub-tool presents the trace signals by their
names (see chapter 9.2.3 Trace Signals and
chapter 9.3.3 Trace Signals). Each Signal Chooser shows the
signal data and configures the graphical display, see
Illustration 5.31.

Callout Description Function
1 Channel Shows the index of the channel that is
index controlled by the Signal Chooser. The
signal channels are numbered 1–8 (see
Illustration 5.28).
2 Channel The checkbox controls whether the given
activation channel is recorded on the device. By
checkbox selecting and deselecting the channel
activation checkboxes, the number of
signals to be traced in the next trace is
configured.
3 Channel Sets the color in which the traced data for
color the given channel is visualized. The color
of a channel can be changed at any time.

Function
Value at The left and right cursor fields show the
right cursor values of the trace data at the 2 cursors in
the unit shown by signal unit. The 2 fields
are updated dynamically while dragging.
The value fields show the traced values
with the precision of 6 decimal places.
Signal unit The unit in which the traced data for the
signal is shown.
Auto scale Calculates the best scale and offset for
showing the entire graph on the plot and
performs them.
Modifies the vertical scale and the vertical
offset of this signal (see
chapter 5.7.3.8 Trace Visualization).
Vertical Both an input and a visualization control
offset for the vertical offset of the signal. A
vertical offset of 0 means that the vertical
zero-point of the graph is located exactly
in the vertical center of the plot area. The
offset value is shown in the same way as
the vertical scale and the values at the
left and right cursors: with 6 decimal
places and in the unit shown by Signal
unit.
The vertical offset can be modified in 3
ways:
•
Type in the desired offset in the
Vertical offset field.
•
Use the up/down arrows on the right
of the Vertical offset.
•
Auto-scale the trace using the Auto
scale button (modifies the vertical
scaling and the offset of this channel).
