The cursor function
In addition to the zoom and scaling function, there is the cursor function which is called by
double-clicking the Channels list field.
The double-click opens a list of all signal sources with the following options:
•
Display of individual measured values of a selectable channel
•
Addition, subtraction or multiplication of any two measured values
•
Square-law mean value of any two measured values
How to use the cursor function:
1. Go to the oscilloscope toolbar and click the "Cursor" button to activate the cursor function.
a) Two movable vertical measuring lines are displayed in the oscillogram.
2. Select the channel for which individual measuring lines are to be displayed from the Chan-
nels list field.
3. Hold down the left mouse button and drag the red vertical measuring line to the desired
position.
a) The active measuring line is represented by a continuous line, the inactive measuring
line is represented by a dotted line.
b) If you position the mouse pointer over the inactive measuring line, the measuring line
automatically becomes active.
c) The columns yPos I and yPos II in the Channels list field display the values measured at
the measuring lines. The column ΔyPos or QWM displays the cursor differential value or
square-law mean value of all values between both cursors.
d) The sum value to be displayed can be defined in the "tool settings" dialog. This dialog
can be set via the "Tool settings" dialog on the right in the toolbar.
e) Comparing peak values: Several values displayed in the oscillogram can be compared to
each other using a horizontal measuring line. The measuring line is automatically cre-
ated based on the current cursor point and thus cannot be shifted.
Managing oscillograms
If several data records are loaded in the oscilloscope at the same time, the measured data to
be displayed is selected via the respective tab above the displayed oscillogram. There are
three types of oscillograms:
•
Device oscillogram
The device oscillogram is the only oscillogram to establish a connection to the target sys-
tem in order to carry out an oscilloscope measurement. It is always displayed as the first
"Device on the left" tab.
•
Offline oscillogram
The offline oscillogram is an oscillogram already saved in the Engineering PC.
•
The configuration of the offline oscillogram can be reused for future recordings.
•
The offline oscillogram is displayed as a tab with the file name that was allocated for
this oscillogram while being saved.
•
Merge oscillogram
The merge oscillogram ("Merge" tab) is automatically available if two or more oscillograms
are loaded in the oscilloscope at the same time.
•
In the merge oscillogram, several characteristics from the currently loaded oscillograms
can be overlaid, e. g. to compare signal characteristics from different recordings.
Commenting oscillograms
You can add a comment on the selected oscillogram into the comment input field.
•
When you execute the "Save oscillogram" command, the comment is saved together with
the oscillogram in the file.
•
When you select an oscillogram with a comment to be loaded in the "Load oscillogram"
dialog box, this comment is displayed in the dialog box.
