9 Search Functions
Search functions allow you to detect and analyze specific conditions in the acquired data
quickly and simply. This is possible for running acquisitions. Various search conditions
are available, including trigger parameters such as edges, windows or states. Search
results can then be qualified further by other waveform conditions.
Simple searches can be performed very quickly and easily; with some additional config-
uration, even complex searches are possible.
The results are displayed in a table and optionally in a zoom window.
9.1 Search Conditions and Results
To make the search functions suit your requirements, both the search conditions and the
result display are configurable. You can define up to 8 different searches and let them
run simultaneously. For each search, you can define the conditions, scope, and result
display separately. The settings of a search are deleted when you close its search result
box.
9.1.1 Search Conditions
Search scope
Searches can be performed for any input signal, math or reference waveform. Either the
entire waveform can be searched, or only a defined (gate) area.
Search control
Searches can be performed online, that is repeatedly for each new data acquisition, or
only once.
Search conditions
Various different search conditions are available, depending on the source waveform.
For trigger searches, most parameters available for trigger event definition can also be
configured as search conditions. However, unlike triggering, you can configure several
trigger event types to be searched for simultaneously, and search in any signal, math or
reference waveform. For details on trigger search conditions see "Search condi-
tions" on page 243.
Frequency marker searches detect peaks in a spectrum. For this search type you can
define the peak excursion.
9.1.2 Search Results
The results are displayed in a table and optionally in a zoom window.
