1. Press SHIFT+ZOOM (SEARCH). The SEARCH menu appears.
Selecting the “Width” Search Type
2. Press the Type soft key. The Type menu appears.
3. Press the Width soft key.
Setting the Search Conditions
4. Press the Setup soft key. The Setup dialog box opens.
Setting the Pulse Width Determination Type, Search Target Waveform, Level,
Polarity, Hysteresis, Pulse Width, and Search Start Point
5. Use jog shuttle & SELECT to select the determination type (Type box).
6. Use jog shuttle & SELECT to select the search target waveform (Source box).
7. Use jog shuttle & SELECT to set the level for determining whether the polarity
is high or low (Level box).
8. Use jog shuttle & SELECT to select the polarity, high or low, used to perform
determination (Polarity box).
9. Use jog shuttle & SELECT to set the hysteresis (width of the level for detecting
the edge) (Hysteresis box).
• 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.
• For the determination of the polarity when the change in the search target level does
not apply to high or low conditions described above, see the explanation given later.
10. Use jog shuttle & SELECT to set the pulse width (determination time) used as
the determination reference (Time box).
11. Use jog shuttle & SELECT to set the search start point (Start Point box).
12. Press ESC. The Setup dialog box closes.
