Setting Scale

The soft oscilloscope graph is divided into eight units for the horizontal time scale (X-axis) and eight units for the amplitude (Y-axis).

These units can be user-defined by using these configuration panels:

Unit per Division

This is the time-base value for the X-axis and the amplitude value for the Y-axis.

Example: If the time-base is 10ms and the amplitude is 1, each division in the soft oscilloscope grid corresponds to a time of 10ms for the X-axis and an amplitude of 1 for the Y-axis.

Time Scale

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:

Description

Used to divide / multiply the time-base by 2.

  • Performing a division corresponds to a zoom in.
  • Performing a multiply corresponds to a zoom out.

Used to divide / multiply the time-base by 10.

The base time unit is 1 ms.


  • Modify the time scale by scrolling the mouse wheel with the cursor located in the graphical area.

Variable Scale

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 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.
