Precautions to be Taken when Searching
• Searching is not possible while the data acquisition is in progress.
• Searching is not possible on the computed results of the power spectrum.
• The search result is void if the following operations, are carried out:
Starting data acquisition.
Changing the Search Setup setting.
Shifting the phase of the source or the clock.
• Searching is not possible when setting CH2 or CH4 as the clock channel while in
high-resolution mode.
• Searching is not possible when all patterns are set to X.
• Patterns from undisplayed waveforms will not be referenced during searcles.
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).
Start Point of the Search
Detected Position
The Upper Value
of Hysteresis
This rising slope is not counted as an edge.
Specified Level
When the Edge is Set to Rising
and the Count is Set to 2
The Lower Value
of Hysteresis
Determination when Searching Using a Serial Pattern
The points between the Thr Upper and Thr Lower are always determined to be true
(matches the specified status). If such a point is included at the time the pattern is
checked, a message is displayed as a notification.
