Pattern Search
Set the search source pattern and whether a clock source is available. The instrument searches for positions
that meet the specified conditions.
When a Clock Source Is Specified
Search Example 1
The results of comparing the combination (Logic) of the trigger source signal pattern (Pattern) and the specified
pattern are sampled on the edges of the clock source, and the instrument searches for the point of change in the
comparison results (Enter or Exit of the search condition (Condition)).
Clock: CH3,
Pattern: CH1 = H, CH2 = L, other channels = X, Logic = AND
Condition: Enter

Search Example 2
When the result of comparing the combination (Logic) of the trigger source signal pattern (Pattern) and the
specified pattern is true or false as specified by the achievement condition (Condition), the instrument searches
for the edge of the clock source.
