Click the [Type] box, and then choose a save format of waveform data or save target from
the list.
Waveform
(Binary)
Saves waveform data in binary format. Choose this option to reload the waveforms into
the instrument.
Waveform (Text) Saves waveform data in text format. Choose this option to load the waveform data into
a computer.
The instrument cannot read this type of les.
Waveform (Float) Saves waveform data in binary format (32-bit oating point).
Choose this option to load the waveform data into MATLAB. The instrument cannot
read this type of les.
Screen image Saves image data on the screen in BMP, PNG or JPEG format.
You can display the data saved on a computer with image viewing software.
Calc. Result Saves numerical calculation results.
Setting Saves the present measurement conditions.

Tap the [Channel] box, and then choose an option for channels to be saved.
All Saves measured data of all channels.
The instrument also saves data acquired across channels with the waveform display
set to [Off].
Display
Saves the data acquired across the channels of all sheets with the waveform display
preferences set to [On].

Measuring Signals With the Auto-range Setting
3.7 Measuring Signals With the Auto-range Setting
The auto-range function is available only for signals inputted to analog measuring modules.

Click [Auto range] on the waveform screen.

Click [Execute].
The instrument species the sampling rate, measurement range, and zero position for each input
waveform automatically and starts a measurement.
The sampling rate is specied according to the lowest numbered channel of the channels with
[Display] set to [On]. In addition, it is automatically specied so that waveforms have a length of
between 1 cycle and 2.5 cycles while 2500 points are recorded.
The auto-range function changes the following items:
Module conditions (for all channels)
Range (f.s.)
Automatically specied value
Zero position
L.P.F Off
Input coupling DC
Triggering condition (for one channel only)

Pre-trigger 20%
Internal trigger Detects trigger levels beginning from the channel lowest-numbered
among the channels with the [Display] button set to [On].
