Searching For Positions Where a Trigger Condition Is Satised
6
Click [Execute].
The instrument puts search marks ( ) on positions where the search criterion is satised. You can search for
up to 10,000 points. The instrument stops the search if it nds more than 10,000 positions.
The retrieved position switching panel appears on the waveform screen.
To stop the search
Click the stop icon.
7
Switch retrieved positions using the [Search Pos.] switching panel and check the search
results.
You can switch the retrieved positions by clicking [<] or [>].
The display order follows the setting in [Display order].
Clicking [Next] executes another search beginning from the next point of the retrieved position presently
displayed. The instrument discards a previous search result.
To specify a retrieved position and jump there
As described in “6.4 Jump to the Specied Position” (p. 132), choose [Search number] in the [Type] box,
and then click [Execute].

Searching For Differences from a Fundamental Wave (Memory HiConcierge)
6.3 Searching For Differences from a Fundamental
Wave (Memory HiConcierge)
Using Memory HiConcierge allows you to detect differences from the specied fundamental
waveform based on a histogram or standard deviation.

1
Click the [Target channel] box, and then from the channel setting dialog box, choose a
channel to be searched for differences.
2
Click the [Number of searches] box, and then enter the number of search results.
3
In the [Method] area, click [Concierge] to set the search method to Concierge.
4
Click the [Type] box, and then from the list, choose a value type to be searched for.
Histogram (comparison with
fundamental wave)
Searches for differences from the specied fundamental wave
based on a histogram.
Histogram (comparison with
previous waveform)
Searches for differences from the previous waveform based on a
histogram.
Standard deviation (comparison with
fundamental wave)
Searches for differences from the specied fundamental wave
based on a standard deviation.
Standard deviation (comparison with
previous waveform)
Search for differences from the previous waveform based on a
standard deviation.
The instrument searches whole measured waveforms. You cannot specify a segment to be searched.

Searching For Differences from a Fundamental Wave (Memory HiConcierge)
5
Use the [Period setting] toggle switch to choose a period setting used for searches.
The instrument searches for differences from the fundamental wave (or the previous waveform) in the
specied intervals.
Auto
The instrument automatically saves calculation results.
Any Allows you to click the [Sample] box to enter the number of samples, which species a
period.
With the [Auto] setting, the instrument may not be able to determine a period depending on measured
waveforms. If a fundamental wave have an unintended form, change this setting to [Any] and specify a period
in the number of samples in the [Sample] box.
6
Click [Refresh fundamental wave] to display the fundamental wave.
The instrument extracts a fundamental wave from the specied period and displays the wave on the screen.
7
Click the [Display order] box, and then from the list, choose a sort criterion for search
results.
Sort by time
Displays retrieved positions in chronological order.
Sort by data Displays retrieved positions in order of decreasing difference from a comparison target
(fundamental wave or previous waveform).
8
Click the [Number to display] box, and then enter the number of search results to be
displayed.
9
Click [Execute].
The instrument puts search marks ( ) on positions where the search criterion is satised.
The retrieved position switching panel appears on the waveform screen.
To stop the search
Click the stop icon.

Switch retrieved positions using the [Search Pos.] switching panel and check the search
results.
You can switch the retrieved positions by clicking [<] or [>].

displayed. The instrument discards a previous search result.
To specify a retrieved position and jump there
