Explanation
This section explains the setup procedures for searching history waveforms that meet or
do not meet the specified search parameter conditions.
Search Parameters
You can register up to four search parameters, Param1 to Param4. For each search
parameter, you can set the search conditions below. You can also set whether to use
AND or OR logic of the search conditions of the four search parameters to perform the
search (see “Search Logic” described later).
• Status of the search parameter for the searched waveform
• Target waveform/search measurement item
• Determination range of the measured value of the search measurement parameter
• Search range
Status of the Search Parameters for the Searched Waveform: Condition
You can select from the following.
OFF: No search is performed.
IN:
Searches for waveforms whose measured value of the search and measurement
parameter is within the determination range of the specified search parameter.
Search is also made on boundary values.
OUT: Searches for waveforms whose measured value of the search and measurement
parameter is not within the determination range of the specified search
parameter.
Selecting the Search Target Waveform/Search Measurement Item
You can select the target waveform and the measurement parameter to be used as a
search condition. If a waveform that meets the search condition is found, other history
waveforms at the same time as the found waveform are also displayed.
Waveform to Search
• For the DL1735E/DL1740E/DL1740EL
You can select the target waveform from CH1 to CH4, Math1, and Math2.
• For the DL1720E
You can select from CH1 to CH2, and Math1.
Search Measurement Items
Same as the measurement parameters of the automated measurement of waveform
parameters. See section 10.6.
Determination Range of the Measured Value of the Search Measurement
Parameter
You can set the upper and lower limits of the determination range. The selectable range
is –9.9999E+30 to 9.9999E+30. The upper limit (Upper) must be greater than or equal to
the lower limit (Lower)
Search Logic
You can select the AND logic or OR logic of the search conditions of the four search
parameters in performing the search.
AND: Searches for waveforms that meet all search conditions of Param1 to Param4.
OR:
Searches for waveforms that meet one of the search conditions of Param1 to
Param4.
Search Range: T-Range1/T-Range2
The selectable range is
±
5 divisions, and the resolution is ten divisions
÷
display record
length. The right end of the search range (T-Range2) must be greater than or equal to
the left end of the search range (T-Range1).
