X-Mag.

If the "X-Mag." button is on, the width of the image plane is stretched to 10 times of its original size. This means, a signal is stretched 10 times horizontally, but it remains in its original size vertically. The "X-Mag." operating mode is well suited to make details of a curve visible.

In the simulation a curve can be shown stretched 10 times as well. Cpu timing limitations however demand for drawing a curve with 260 samples or less only. This leads to a coarse curve in some configurations. In a real oscilloscope the display quality would remain the same, of course.

The following screenshot illustrates the problem:

Using 24 values only a width of 260 pixels must be covered and still a maximum calculation speed must be received. In long "Time/Div." settings and 10x zoom therefor the display quality is considerably lower.
