Notes When Searching
• Searching is not possible while the data acquisition is in progress.
• The search result is void if the following operations are carried out:
• When data acquisition is started.
• When Search Setup is changed.
• Patterns of waveforms that are not displayed are not searched.
• If the waveform is inverted or the offset voltage is changed, the search is performed
on the waveform after the change.
Determination When Using the Edge for the Search
When the peak immediately after the rising edge of the waveform is less than or equal to
the upper limit of the hysteresis or when the peak immediately after the falling edge is
greater than or equal to the lower limit of the hysteresis, it is determined as false (not
counted as a specified edge).
Specified level

Detection position
Upper limit of
hysteresis
This rising edge is determined to be false.
When the edge is set to rising and the count is set to 2
Lower limit of
hysteresis
In addition, in the determination of logic waveforms, the determination is performed two
points after the detected position.

Auto Scroll
Set the scroll speed using 10 levels from 1 to 10. The speed increases as the number
gets larger. You can only change the Direction and Speed while auto scroll is in
progress.
Playing of the Voice Memo (Voice Search)
When using the voice search function, the voice memo that has been found can be
played by pressing the Play Start soft key. The voice memo can be played only when
the searched item is the newest waveform that has been acquired to the acquisition
memory. While the voice memo is being played, Play Start indication changes to Play
Stop. To stop the voice memo while it is playing, press the Play Stop soft key. When
the voice memo is finished playing Play Stop automatically changes to Play Start even if
the Play Stop soft key is not pressed.
Note
Waveform acquisition cannot be started when the SEARCH menu is displayed.
