Analyzing and Searching Waveforms

Hysteresis
You can set the hysteresis. The selectable range is 0.3 divisions to 4.0 divisions. The
resolution is 0.one divisions.
• The interval from the point where the level of the search target waveform passes from
below the specified lower limit of hysteresis to above and including the upper limit of
hysteresis to the point where the level changes from above the specified upper limit of
hysteresis to below and including the lower limit of hysteresis is determined to be the
high pulse width.
• The interval from the point where the level of the search target waveform passes from
above the specified upper limit of hysteresis to below and including the lower limit of
hysteresis to the point where the level changes from below the specified lower limit of
hysteresis to above and including the upper limit of hysteresis is determined to be the
low pulse width.
• When the change in the search target level does not apply to high or low conditions
described above, it is not detected as a high or low pulse width.
Level
Upper limit of hysteresis
Lower limit of hysteresis
Detected as a low pulse width.
Detected as a high pulse width.
Handled as an area where the search condition is not met.
Determination Time: Time, Time1/Time2
You can set the time used as a determination reference. The value specified here and
the pulse width detected by the specified search condition are compared, and
determination is made as to whether the result matches the selected type. The
selectable range is (1/sample rate) to the display range. For a description of the sample
rate, see appendix 1.
Search Start Point
You can set the search start point. The selectable range is
±
5 divisions. The resolution is
ten division
÷
display record length. For a description of the display record length, see
appendix 1.
Auto Scroll Search Conditions
The following conditions can be specified.
When auto scroll is in progress, you can only set the direction and speed of the auto
scroll operation.
Auto Scroll Direction
You can select the auto scroll direction.
<<: The zoom box automatically scrolls to the left. It can scroll up to the left end of the
screen.
>>: The zoom box automatically scrolls to the right. It can scroll up to the right end of
the screen.
Speed
You can set the auto scroll speed. The available setting range is 1 to 7. The larger the
value, the faster the scrolling.
