16 Displaying and Searching History Waveforms
Search Condition Settings for Waveform Parameter Searching
(Search Setup)
Search Parameter (Select Param)
You can register four search conditions to Param1 to Param4. For each search condition, you can change the
channels to search, the search condition, and the search range.
Search Condition (Condition)
• IN: The DL850E/DL850EV searches for waveforms in which the specified parameter is within the specified
range.
• OUT:
The DL850E/DL850EV searches for waveforms in which the specified parameter is outside the specified
range.
•
OFF: The DL850E/DL850EV does not search for waveforms.
Source Waveforms and Parameters (Source)
The DL850E/DL850EV searches through the specified parameter of the specified trace (Trace). You can specify
one type of automatically measured waveform parameter. However, you cannot search through the waveforms
of a 16-CH voltage input module, 16-CH temperature/voltage input module, CAN bus monitor module, or CAN &
LIN bus monitor module.
Search Condition Upper and Lower Limits (Upper and Lower)
Specify the range used to determine the condition of the specified parameter.
Search Logic (Logic)
• AND: The DL850E/DL850EV searches for waveforms that meet all the search conditions specified for Param1
to Param4.
• OR: The DL850E/DL850EV searches for waveforms that meet at least one of the search conditions specified
for Param1 to Param4.
Parameter Measurement Time Period (Time Range1/Time Range2)
You can set the measurement time period for the specified parameter by setting Time Range1 and Time Range2.
The default settings are −5 div and +5 div. The number of data points in the measured waveform can be up to
100 Mpoint from the start of the measurement time period.
Selectable range: −5 div to +5 div
The measurement time period is similar to the settable range of the cursor display position in cursor
measurement.
For details, see “Selectable Range of Cursor Positions.”
Search Execution (Execute Search)
Searches for waveforms that meet the specified search conditions and displays only the waveforms and
timestamps that are detected.
Notes about Using the History Feature
• You can start waveform acquisition when the History menu is displayed. However, you cannot change the
history feature settings while waveform acquisition is in progress.
• When the acquisition mode is set to Average, you cannot use the history feature.
• Y
ou cannot use the history feature when you are using the dual capture feature or during hard disk recording.
• If you stop waveform acquisition, even if one complete screen’s worth of waveform data has not been
acquired, the waveform at which the trigger occurred is displayed as a single history waveform.
• If you stop waveform acquisition and then start it again without changing the waveform acquisition conditions,
the waveform data continues to be stored in the acquisition memory.
• If you change the waveform acquisition conditions and start waveform acquisition, the past data stored in the
acquisition memory is cleared.
