Explanation
Data Type
• ACQ Memory
• The sampled data in the acquisition memory is saved in binary format.
• The data that is saved can be loaded into the DL9000. Then, the DL9000 can
display the waveform and compute the numeric data.
• Y
ou can use the Xviewer software application by
YOKOGAWA to analyze
waveforms on a PC. For details, contact your nearest YOKOGA
WA dealer. A trial
version is available at the YOKOGAWA’s Website.
• The extension is .wdf.
• ASCII
• The units of the sampled data in the acquisition memory are c
onverted per the
specified range and saved in ASCII format.
The data can be used to analyze the
waveform on a PC.
• The file cannot be loaded into the DL9000.
• The extension is .csv
.
• Float
• The units of the sampled data in the acquisition memory are c
onverted per the
specified range and saved in 32-bit floating format. The data can be used to
analyze the waveform on a PC.
•
The order of the data is little-endian (Intel format).
• The file cannot be loaded into the DL9000.
• The extension is .fld.
Data Size
The following table shows the data size when the record length is set to 125 kW,
measurement data of CH1 to CH4 are saved, and using history waveform 1 condition.
Data Type Extension Data Size (Bytes)
ACQ Memory .wdf Approx. 1 M ((125 kW + 12) × 4 channels × the number of
history waveforms × 2 + 150 K)
ASCII .csv 9 to 10 M
Float .fld Approx. 2 M (((125 kW + 12) × 4) × the number of history
waveforms × 4)
Waveforms to Be Saved
• You can save all waveforms or select waveforms from CH1 to CH4, and M1 to M4.
• The setup data including vertical axis, horizontal axis, and trigger of the waveform to
be saved is also saved.
• For waveforms that are loaded using the history memory funct
ion, you can select
whether to save all of the history data, or save just the current displayed waveform
on the screen. Y
ou can also save only the results obtained by searching the history
memory data. For details on searching history memory data, see Chapter 11.
• If you select all waveforms, the displayed waveforms from CH
1 to CH4, and M1 to M4
are saved. However, computed waveforms that use CH2 or CH4 as sources cannot
be saved in interleave mode.
