Split the diagram

1. Split the diagram
VM-TRACK provides magnitude and phase. Both can be displayed in the measurement chart. You can select whether one of them is to be shown mainly (using more space) or only.

Grid density

2. Grid density
 If you activate this checkbox, VM-TRACK will show grid lines at all graduation marks of the Y-axis.

Permanent autoscaling

3. Permanent autoscaling
If you activate this checkbox, VM-TRACK will rescale the Y-axes each time the measurement chart is refreshed, using the last scaling mode.

Scaling mode

4. Scaling mode
There are four scale modes:
  • All curves are maximized.
  • Same scale for all curves.
  • All curves are maximized and stacked with their own area.
  • All curves use the same scale, they are stacked with their own area.

Step size

5. Step size
The step size (shown in scale lengths), by which measurement curves and scale are shifted during a movement. For instance, 10% means that the measurement curves are moved by 1/10 of the Y axis.

Compress / expand

6. Compress / expand
These buttons expand or compress all measurement curves in Y direction.

Adjusting the phase display

The phase display of the signal can be adjusted by right-clicking on the y-axis of the phase-speed diagram. Three display options are available:
Display of -180° to +180°. Phase values less than -180° resp. greater than +180° are drawn in the same diagram.
Display of 0° to 360°. Phase values less than 0° resp. greater than 360° are drawn in the same diagram.
Ongoing scale. The scale expands to any size.
