Saving and Loading the Data from a Floppy Disk
9
Explanation
Saving the measurement results
• Selecting the data type
Select the desired data type from the following.
• BIN: The measurement results are saved in binary format. Once they are saved, they can be
loaded to the instrument.
• TEXT:
• Hardware histogram mode: Values (representative values) in the histogram window and their
frequency are saved in text format. They cannot be loaded to the instrument after they are
saved.
• Time stamp mode: All the data (time stamps and measured values) of a measurement block
are saved in text format. They cannot be loaded to the instrument after they are saved.
• File name extension and directory
File name extension and directory vary depending on the data type. An appropriate extension is
attached to the file name before the file is saved in its corresponding directory.
• BIN: “.WVF” is attached to the file name, and the file is saved in the directory TA_WAVE.
The header file (ASCII format) is also saved at the same time. The header file contains the
information to be used for analysis of the saved data. The extension for the header file is
“.HDR”.
• TEXT: “.CSV” is attached to the file name, and the file is saved in the directory TA_TEXT.
• Data size
The data size varies depending on the number of samples (S) and data type. (Unit: bytes)
• BIN:
• Measured data obtained in hardware histogram mode: Approx. 133 K bytes (approx. 384 K
bytes for simultaneous positive/negative measurement of pulse width measurement)
• Measured data obtained in time stamp mode: Approx. 8 bytes
×
S + approx. 8 K bytes
• TEXT: The data size varies considerably depending on the selected sampling mode, sample
size and histogram display etc. However, the maximum data size is approx. 1 M bytes.
Saving the statistical computation results
• File name extension and directory
“.CSV” is attached to the file name, and the file is saved in the directory TA_MISC.
• Data size
Each computation data requires approx. 500 bytes.
Checking the free space available on a floppy disk
Refer to 9.2.
Entering the file name
Refer to 9.3.
Note
• Loading and saving are not possible during measurement (i.e. while the START indicator is ON).
• Loading of measurement results (text format) and statistical computation results to this instrument is not
possible.
• If measurement results are loaded, the set-up information accompanying the loaded measurement results
will be used as the set-up information.
• If the extension of a file name is changed using a personal computer etc., it will be impossible to load that
file.
CAUTION
Never remove the floppy disk while the access indicator is blinking. Failure to do so
may damage the magnetic head of the floppy disk drive or destroy the data saved on the
floppy disk.
