Chapter 8 Trigger Settings
8
Trigger settings can be used to search measurement data.
Locations that match the set trigger criteria in the measurement data are searched for and displayed
sequentially.
Using the same method to set triggers, it is possible to search for criteria different to those at the
time of measurement.
Example 1: The measurement trigger criteria is trigger level 0 V and the data search condition is
level 100 V.
Example 2: After measurement with a free run without a trigger, locations that exceed 100 V are
searched for.
8.12 Using trigger settings to search
measurement data
Procedure
To open the screen: Right-click and select [DISP] Waveform screen Right-click and select [TRIG.SET]
Trigger settings window ([Analog Trig], or [Logic Trig] sheet)
1
After measurement is finished, set the search criteria.
The setting method is the same as described in "8.3 Trigger-
ing by Analog Signals" (p.192) and "8.4 Triggering by Logic
Signals (Logic Trigger)" (p.197).

Specify the search range.
Move the flashing cursor to the [Area] item.
Select

Execute search.
Move the flashing cursor to the [Trig search] item.
Select
Whole Wave Search all measured data. (default setting)
A-B Wave
Search in the range between A/B cursor.
Whole Display
Blocks
Applies search to the whole display blocks.
A/B Display
Blocks
When setting the A/B cursors on the display blocks, ap-
plies search to the range between the A and B cursors on
the display blocks.
Whole Blocks
Applies search to the data in the whole blocks.
A/B Whole
Blocks
When setting the A/B cursors for the whole blocks, applies
search to the range between the A and B cursors for the
whole blocks.
Execute
search
Start the search from the beginning of the measurement
data.
Search next
Searches for the next search condition at the most recent
search position.
Move A cursor
Move A cursor to the searched position.
Move B cursor
Move B cursor to the searched position.
Clear
Clear the searched position.

• When selecting A/B range and only
A cursor is shown on the screen,
search will be performed on the
data after A cursor.
• The search range for [Whole
Blocks] and [A/B Whole Blocks]
will be defined according to the
start block and the number of
blocks to be measured.

Description Search results
Locations that match the criteria are displayed in the center of the screen and an
S mark is displayed in this position.
When no matches are found, a message
stating that no matches were found is dis-
played.
• Pre-triggers, trigger priorities, external triggers and timer triggers cannot be
used as search conditions.
• The trigger position and search results may not match.
• Data measured with MR8990 Digital Voltmeter Unit cannot be searched.

Numerical calculations can only be used with the Memory function.
Results calculated from the acquired waveform are displayed as numerical values on the Waveform
screen. Numerical calculation settings are made on the Status screen - [Num Calc] sheet.

Waveform calculations can be limited
to data within the range specified by A/
B cursors.

MR8990 Digital Voltmeter Unit is in-
valid.
Calculation operator details:
"9.5 Numerical Calculation Type and
Description" (p.223)
Numerical Calculation Judgment (p.218)
The result of a numerical calculation can be compared to a
preset reference range, for GO/NG (Pass/Fail) evaluation.

Operations available from the [Num Calc] sheet
There are a total of 24 types of numerical
calculations, 16 of which can be performed
simultaneously.
When the Scaling function is used, numeri-
cal calculation is performed on the scaled
value.
