![1](drex_bullet_1.png) Grid density
|
Draws the fine grid for Y
|
| |
![2](drex_bullet_2.png) Permanent autoscale
![2. Permanent autoscale](drex_display_of_traces_4_control_2.png) Scales the Y axis at each measurement with the selected scale mode
| |
![3](drex_bullet_3.png) Scale mode
|
Two modes are available:
• All curves with same scale
|
| |
![4](drex_bullet_4.png) Expand / compress (Y)
|
Expand or compress all curves in Y direction
|
| |
![5](drex_bullet_5.png) Move
|
Shift all curves in the desired direction
|
| |
![6](drex_bullet_6.png) Expand / compress (frequency)
|
Expand or compress all curves in frequency axis direction (only for acoustic measurements)
|
| |
![7](drex_bullet_7.png) Autoscale
|
Scale all lines so that they are at least 5 % of the maximum amplitude (only for acoustic measurements)
|
| |
![8](drex_bullet_8.png) Decadic grid
|
Label the frequency axis in octave, 1/3, 1/6 or decadic intervals.
Example for 1/3 octave:
Decadic:
