1. Data saving
Destination to save
SSD:
USB ash drive:
FTP transfer:
Email transmission:
Built-in SSD (storage capacity: 480 GB)
Model Z4006 USB Drive (16 GB)
Computer connected via LAN
The instrument sends email messages with a le attached to
user-dened destination.
File format FAT, FAT32, NTFS, exFAT
File name Alphanumeric le names can be entered.
Handling of same-
name les
Prexes a sequential number to the le name and saves the le. (For FTP transmission,
sufxes data and time)
Auto-save On/Off
* Automatically saves the acquired data with a recording length after each measurement.
* No setting les are supported.
* Not available when the real-time save is selected.
Real-time save On/Off
* Directly saves waveform data (binary) acquired during measurement to the save
destination.
* Auto-save setting is unavailable.
Older-le overwriting If a free space of a destination is insufcient, the existing les are overwritten beginning
with the oldest.
(Available with the auto-save setting)

Channels to be
saved
When the saving format is set to the measured data, the channels to be saved can be
selected between all channels and displayed channels.
Data decimation
save
With the saving format set to measured data (in text format), data is decimated by retaining
one out of the specied decimation number (2 to 1000) and the remaining data is saved.
File division
Saving format Division content
Binary format Off, every 16 MB, every 32 MB, every 64 MB
Text format Off, every 60,000 data points, every 1,000,000 data points
Numerical
calculation result
Off, by calculation number
File designation New le or existing le
(Enabled when the saving format is set to the numerical calculation result)
(Before starting a measurement, select whether a new le is created or data is appended
to the existing le)
Save operation
Quick save: The save icon is used to save data based on a preset destination, le name,
and saving setting.
Saving range: All or a specied segment range can be selected.
(Available only for saving data started by click the save icon)

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
