Maximum
Allows you to search for the maximum value.

Click the [Filter(samples)] box, and then from the list, choose a decision criterion for
maximal or minimal values.

Regards a value as a maximal value when it is larger than the values found one point
before and after, and a minimal value when it is smaller.
10 to 10,000 Regards a value as a maximal value when it is larger than all the values found the
specied number of points before and after, and a minimal value when it is smaller.

(When you choose [Maximal] or [Minimal] in the [Type] box)
Click the [Display order] box, and then from the list, choose a sort criterion for search
results.
Sort by time
Displays retrieved positions in chronological order. You cannot enter the number in the
[Number to display] box. The instrument handles up to 10,000 search results. The
instrument stops the search if it retrieves more than 10,000 results.
Sort by data With the [Maximal] setting, displays the number, which is specied by [Number
to display], of retrieved positions in descending order. With the [Minimal] setting,
displays them in ascending order.
(When you choose [Sort bya data] in the [Display order] box)
Click the [Number to display] box, and then enter the number of search results to be displayed.

Click [Execute].
The instrument puts search marks ( ) on positions where the search criteria are satised.
The [Search Pos.] switching panel appears on the waveform screen.
To stop the search
Click the stop icon.
9
Switch retrieved positions using the [Search Pos.] switching panel and check the search
results.
You can switch the retrieved positions by clicking [<] or [>].
The display order follows the setting in the [Display order] box.
Clicking [Next] executes another search beginning from the next point of the retrieved position presently
displayed.
The instrument discards a previous search result.
To specify a retrieved position and jump there
As described in “6.4 Jump to the Specied Position” (p. 132), choose [Search number] in the [Type] box,
and then click [Execute].
