Search Results box
Search results are displayed in a "Search Results" box with a tab for each search con-
dition and one for the combined results. Each tab contains a table with the position and,
if available, further parameters for each result. The tables can be sorted by x-position or
value. You can define a maximum number of table entries. As with all result boxes, you
can minimize it to a result icon in the signal bar, or display results in a separate table like
a diagram on the screen. When you close a search results box, all settings of this search
are deleted.
Search zoom windows
The search results can be displayed in a zoom window, which allows you to analyze the
search results in more detail. By default, a zoom window is displayed for the currently
selected search result. The zoom area is indicated in the diagram that displays the source
waveform of the search. You can switch off the zoom diagram in the "Search" dialog box.
9.2 Configuring and Performing Searches
Besides the basic search settings such as the source and conditions, the scope and result
presentation can also be configured. Searches can be performed only once or continu-
ously on running acquisition.
Simple searches can be performed very quickly and easily; with some additional config-
uration, even complex searches are possible.
9.2.1 Configuring a Trigger Search
Trigger searches look for conditions in the signal that can lead to a trigger event during
data acquisition, by using the same parameters.
To perform a simple edge search
1. Select an active time-based waveform you want to perform the search on.
2. Select the "Search" icon on the toolbar.
3. Tap the diagram with the selected waveform.
The default edge search is configured as "Search<x>" and performed for the selected
time-based waveform. The "Search Results" box is displayed.
To create and configure a more complex trigger search
1. Press the SEARCH key to open the "Search" dialog box.
2. Tap the "Add" icon to create a new tab for the new search configuration, or the
"Copy" icon to copy an existing search configuration.
