Setting Scale

The soft oscilloscope graph is divided into 8 units for the horizontal time scale (X-axis) and 8 units for the amplitude (Y-axis). These units can be user-defined by using the configuration panels described below.


  • Unit per ulision: the term refers to the time-base value for the X-axis and to the amplitude value for the Y-axis. For example, if the user sets a time-base of 10ms and an amplitude of 1, each ulision in the soft oscilloscope grid corresponds to a time of 10ms for the X-axis and an amplitude of 1 for the Y-axis.

The time scale can be configured with the Time-base configuration panel. The default value is 100ms/unit with the limits being 0.1ms to 25,000ms. The new value can be entered by hand directly in the text field or by using the buttons:

Buttons Description
Used to divide / multiply the time-base by 2
(performing a division corresponds to a zoom in while performing a multiply corresponds to a zoom out)
Used to divide / multiply the time-base by 10

The base time unit is 1 ms.


  • You can also modify the time scale by scrolling the mouse wheel with the cursor located in the graphical area.

Variable scaling is done by modifying the amplitude and offset value of a channel.

The variable scale can be configured in different places:


  • You can also modify the variable scale by pressing down the Ctrl key while scrolling the mouse wheel with the cursor located in the graphical area.


  • The changes affect only the selected channel.
