Explanation
Window Mode: Multi
Multiple windows of different sizes can be specified. This mode is used when multiple
histograms are present simultaneously and constant T is known.
Displays the histogram of 3T
Window size
Select multi window
Center value of the window (scale value)
Set the scale value and marker value of each window
Select window to be displayed on the main window
Span value of the window (scale value)
Setting the Window Size
Set the number of windows that will be displayed.
Selectable range: 1 to 14
Constant T(T Value)
Set the interval of the center value of each window as a T value. Constant T can also be
set using the frequency, which is an inverse of constant T rounded to a resolution of 25
ps.
• Selectable range of constant T: 1 ns to 250 ns (25 ps steps)
• Selectable range when setting constant T using the frequency: 4 MHz to 1000 MHz
Setting the Window Offset
Set the window offset.
Selectable range: –100 ns to 300 ns
Update to Window
The constant T value is applied to the center, span, left marker, and right marker values
of each window as follows:
Center:
T
×
[Label]+Offset
Span:
Window span that is greater than T and closest to T
Left Marker:
Center–(T/2)
Right Marker: (T/2)
Example
When T=38 ns, Offset=10 ns, and the Window1 label is 3, the X-axis
setting of Window1 is as follows:
Center = 38
×
3 + 10 = 124 [ns]
Span = 38 (<60) = 60 [ns]
Left Marker = 124 – 38/2 = 105 [ns]
Right Marker = 124 + 38/2 = 143 [ns]
