5.3 Sub Scale
Procedure
The level scale is displayed based on relative values when a differential waveform (based
on LOG values) or normalized waveform is displayed. A level scale based on relative
values is called a sub scale.
Displaying the Sub Scale
Following section 6.5, “Displaying MATH Waveforms” or section 6.6, “Normalized
Display,” you can select a display waveform of differential or normalized.
Automatic Scaling of the Sub Scale
1.
Press LEVEL. The soft key menu for vertical axis settings appears.
2.
Press the MORE 1/2 soft key. The soft key menu for the sub scale appears.
3.
Press the AUTO SUB SCALE OFF ON soft key to select ON.
Setting the Sub Scale REF Position
1.
Press LEVEL.
2.
Press the MORE 1/2 soft key.
3.
Press the SUB REF LVL POSITION soft key. The REF position setting screen is
displayed.
4.
Enter a value using the rotary knob, arrow keys, or numeric key pad.
Note
The sub scale is displayed when a differential waveform (based on LOG values) and
normalized waveform are displayed. When these waveforms are displayed over a waveform
based on absolute values, the absolute value scale is shown on the left and the relative value
scale is shown simultaneously on the right. If the left scale (main scale) is changed to LOG (8
DIV) or linear (10 DIV), the sub scale is displayed to correspond to the DIV count on the main
scale.
