11.8 Saving Waveform Data in ASCII, Binary or AG
Series Format
Function
ASCII format
Waveform data is stored in ASCII format. This is useful when you want to analyze the
waveform data using a personal computer.
Binary format (Float)
Waveform data is stored in 32-bit floating-point format. This is also useful when you want to
analyze the waveform data using a personal computer.
AG format
Waveform data is stored in the format used by YOKOGAWA’s AG series Arbitrary Waveform
Generator. Waveform data acquired by the instrument can be down-loaded to an AG series
unit.
Directories, extension identifiers, capacity required
Refer to the table below. For files used by the AG series, refer to the User’s Manual provided
with the AG series unit.

result by the (number of records).
Waveforms which can be stored
A waveform from only one of the following channels can be stored.
CH1 to CH8, Math1, Math2, All (Traces which have their display turned ON, available only for
ASCII format)
Moreover, no snap shot, accumulated waveform or histogram waveform can be stored. If
multiple records are displayed using the history memory, only the waveform identified by
“Selected Record No.” is stored.
However, for ASCII format and BINARY format, you can choose how to save the waveform
data from the following.
Display=One : Waveform data selected with the Selected Record No.
Display=All
: Waveform data specified from the Start Record No. to the End Record No.
File name and comment
A file name must be provided, but it is not necessary to provide a comment. For details refer to
page 4-2.
Select the data range to save
• For ASCII format and Binary format
Select from the following.
All
: Save the entire record length of data.
Main : Save the display record length (the range displayed on the screen) of data.
Z1
: Save the portion displayed in the Z1 zoom waveform display frame.
Z2
: Save the portion displayed in the Z2 zoom waveform display frame.
• For AG format
You can select any position to start storing.
The number of points stored is 1 K, 2 K, 4 K, or 8 K points from the start point.
Precautions to be taken when saving waveform data
• Storing is not possible while acquisition is in progress. To enable saving, press the
START/
STOP
key to stop acquisition.
• The saved waveform cannot be recalled by the instrument.
• Storing all channels at once is possible only in the ASCII format.
• The maximum number of files that can be saved in a single directory is 100 for each data
format.
