The cursor funcon
In
addion to the zoom and scaling funcon, there is the cursor funcon which is called by
double-clicking the Channels list eld.
The double-click opens a list of all signal sources with the following opons:
•
Displa
y of individual measured values of a selectable channel
•
Addion,
subtracon or mulplicaon of any two measured values
•
Square-law mean value of any two measured values
How to use the cursor funcon:
1.Go to the oscilloscope toolbar and click the "Cursor" buon to acvate the cursor funcon.
a) Two movable vercal 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 eld.
3.Hold down the le mouse buon and drag the red vercal measuring line to the desired
posion.
a) The acve measuring line is represented by a connuous line, the inacve measuring
line is represented by a doed line.
b) If you posion the mouse pointer over the inacve measuring line, the measuring line
automacally becomes acve.
c) The columns yPos I and yPos II in the Channels list eld display the values measured at
the measuring lines. The column ΔyPos or QWM displays the cursor dierenal value or
square-law mean value of all values between both cursors.
d) The sum value to be displayed can be dened in the "tool sengs" dialog. This dialog
can be set via the "Tool sengs" 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 automacally cre-
ated based on the current cursor point and thus cannot be shied.
Managing oscillograms
If several data records are loaded in the oscilloscope at the same me, the measured data to
be displayed is selected via the respecve tab above the displayed oscillogram. There are
three types of oscillograms:
•
De
vice oscillogram
The device oscillogram is the only oscillogram to establish a connecon to the target sys-
t
em in order to carry out an oscilloscope measurement. It is always displayed as the rst
"Device on the le" tab.
•
Oine oscillogram
The oine oscillogram is an oscillogram already saved in the Engineering PC.
•
The conguraon of the oine oscillogram can be reused for future recordings.
•
The oine oscillogram is displayed as a tab with the le name that was allocated for
this oscillogram while being saved.
•
Merge oscillogram
The merge oscillogram ("Merge" tab) is automacally available if two or more oscillograms
are loaded in the oscilloscope at the same me.
•
In the mer
ge oscillogram, several characteriscs from the currently loaded oscillograms
c
an be overlaid, e. g. to compare signal characteriscs from dierent recordings.
Commenng oscillograms
You can add a comment on the selected oscillogram into the comment input eld.
•
When y
ou execute the "Save oscillogram" command, the comment is saved together with
the oscillogram in the le.
•
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.
