Operation
Scrolling through events:
A scroll bar will appear to allow scrolling to previous events in the plot diagram which are not
visible in the display. The large arrow buttons on the bottom, left-hand side also enable
scrolling through the events (down arrow: backward in time, up arrow: forward in time). The
arrows next to both output fields control the display of data strings.
Zooming in on area of plot diagram:
Using the XY cursor, selected areas of the plot diagram can be enlarged (zoomed in).
1.
Click the C
URSOR
O
N
button.
The XY cursor appears.
2.
Position the XY cursor anywhere in the plot diagram and, holding down the left mouse
button, drag the cursor to form a rectangle containing the area to be enlarged.
3.
Release the mouse button.
The selected area is enlarged and adjusted to fit the dialog box. In addition, a vertical
scroll bar appears on the right side of the dialog box. A section can be enlarged with up
to six levels of magnification. The signal names remain unchanged; the colors can be
used to differentiate between the conditions in the plot diagram.
4.
To reduce the zoom factor to the output level, click the Z
OOM
O
UT
button as many times
as is needed.
5.
Click the C
URSOR
O
FF
button to hide the XY cursor.
Calling up a specific event and accompanying data:
Clicking the left mouse button in the plot diagram causes CLV-Setup to display the event
which is closest to the x position of the cursor in all output fields (exception: measured value
table). This allows the accompanying data of a data string to be called up selectively to the
Receive or Transmit output field. The time and increment status of a rising or falling signal
edge can be called up as well.
If the mouse pointer is located directly between two events when clicked, the event which
occurred first is displayed.
Measuring increment status and time differential in plot diagram
Using the measured value table which appears, measurements can be made within the
visible range of the plot diagram. Two measurement cursors are available for this purpose.
They are activated/deactivated with the right mouse button.
1.
Place the mouse pointer over the plot diagram and press the right mouse button.
The first measurement cursor appears.
2.
Place the measurement cursor on an edge of one of the signals.
The corresponding time and the increment status of the first event are displayed in the
output fields I
NCREMENT
1 and T
IME
1 of the table.
3.
Press the right mouse button again.
The second measurement cursor appears.
4.
Place the measuring cursor to the right of the first measuring cursor on an edge of the
same signal or of another angle which you are interested in.
The corresponding time and the increment status of the second event are displayed in
the output fields I
NCREMENT
2 and T
IME
2 of the table.
In addition, the time differential and the increment differential are displayed in the D
ELTA
I
NC
and D
ELTA
T
IME
output fields.
Pressing the right mouse button again or scrolling through the display clears both measuring
cursors, and the table disappears.
