Adjusting mask position
To adjust mask position automatically
When Align Method is [Zero/One/Crossing], touch the Mask Alignment
[Update].
When touching the Mask Alignment [Update], calculate [One/Zero
Crossing] of the currently described waveform and optimize the mask
position automatically.
The mask position is adjusted automatically if the Scale and Offset on the
screen are changed. However, the mask position cannot be changed.
To adjust mask position manually
When Align Method is [User Defined], the mask position, width and
amplitude can be adjusted using the marker.
1. Touch the right side button of and set [Display On] to display the
marker.
X1 X2 Y1 Y2
2. Touch the X1 text box to set the mask position.
3. Touch
the
Δ
X text box to set the mask width.
4. Touch the Y1 text box to set the level 1.
5. Touch
the
Δ
Y text box to set the level 0.
Touching [Center] moves the marker without depending on the
waveforms. In this case, the setting values of X1,
Δ
X, Y1, and
Δ
Y are
initialized.
