How to Improve the Output Levels Display
You can change the display of an existing measurement, for example, if you wish
to see more details to investigate the graph.
This can be done on the Graph tab of the Properties dialog box:
1
Press the Properties button. If you have a mouse connected to your Serial
BERT, you can also click the right mouse button on the graph and select
Properties from the context menu.
2
Switch to the Graph tab.
3
As an example, select Show Measured Points.
With this option selected, all measured points are indicated in the graph with
small squares.
The headline of the graph tells the number of data points included in the display:
101. This corresponds to the chosen threshold resolution of 100 steps per Volt.
With this number of measured points, you do not get very precise results during
the measurement, but it is quickly finished.
Depending on your personal needs, you can trade measurement precision
against test time.
4
Several more options are provided on the Graph tab for you to adjust the display
as you want. For instance, you can use markers for analyzing the graph or open
a zoom window for viewing the details. To find more information, refer to
“Graph Tab” on page 276.
