Waveform search
Search method
Trigger Level, window-in, window-out
Logic trigger points can be searched for when the target channel is set
to the logic channels.
Peak Maximum, minimum, maximal, minimal
Concierge Histogram or standard deviation (For each of them, a target for
comparison can be chosen between the fundamental waveform and
the previously observed waveform.)
Jump Event mark, cursor, time (specied by an absolute time, a relative time,
or the number of points), trigger point, search mark.
Search range All: Whole data stored in the internal memory
Section
designation:
Either one of the areas between cursors A and B and between cursors
C and D is chosen.
Number of points to
be searched for
Up to 10,000 points
Continuous search When the scope of search is found to include retrieved data points more than the specied
number after the search, the instrument can continuously search waveform data points
after the last retrieved data point.
Display method Displays the search result specied as a search position.
Others
Auto-range Available
The instrument automatically selects a sampling rate and measurement range appropriate
for an input waveforms.
(Not available when the external sampling is used.)
Beep sound Three levels are available:
• Off
• Alert
• Alert+Action
Email transmission Email transmission function using SMTP
Transmission timing: When data is automatically saved; when data is saved by clicking the
SAVE icon
Contents of email: The text entered in the Body box is included and a le in the format
specied in the Type box is attached.
Initialization Discarding the existing waveform data, restoring the settings to the initial values, initializing
the instrument
Self-check Memory check, LAN check, media check
Language English, Japanese
Error indication
Warning indication
The instrument displays details of an error or warning.
Time value display Time, time in sexagesimal, date, the number of data points
Zero position display On/Off
Waveform screen
background color
Black or white
Restart permission Permitted or prohibited
Permitted: When a setting is changed during a measurement, another measurement
starts.
Prohibited: Changing any settings are prohibited during measurement.
