By using a PC FTP client, you can transfer files from the instrument's media to the PC and perform
other file operations.
• This instrument is equipped with an FTP (File-Transfer-Protocol, RFC959
compliant) server.
• You can use IE (Internet Explorer) or other popular FTP clients.
To use FTP, the instrument must be properly set up and connected via LAN cable to
the PC.
See: "15.1.1 Making LAN Settings at the Instrument" (p.310)
"15.1.2 Connecting Instrument and PC With LAN Cable" (p.314)
Relationship Between
Storage Media and
Directories
Each of the various types of storage media appears as a directory on the FTP
server.
/RAM ............... Internal memory
/USB1.............. USB memory stick
/STORAGE
....... Storage memory
Limitations
• During measurement, file access is not possible.
• Storage data can be forwarded directly to the PC.
The STORAGE folder will be displayed when there is a storage waveform.
After storage, the following files can be stored in the STORAGE folder:
• Setting file
• Waveform binary file (data.xxx extension, based on the function, are mem,
rec, xyc, and fft)
• Waveform text file(data.csv)
15.3 Accessing the Files on the Instrument From
a Computer (Using FTP)
• The FTP server of the instrument allows only one connection at a time. More
than one PC cannot access the server simultaneously.
• If no command is sent from a PC for more than one minute after connecting to
the FTP server, the FTP may disconnect the PC. Reconnect the FTP.
• FTP operation will be interrupted when measurement is started.
• Before inserting or removing a USB memory stick, terminate the FTP connection.
• Do not perform file operations while FTP is being used.
• With IE, the refresh date of files may not match those of the main instrument.
• With IE, temporary internet files may retain data from their previous access, so
the previous data may be obtained instead of the newest data.
Be careful when moving files by FTP, as some FTP client/browser programs may
delete all selected files or folders from the source if you cancel a transfer before
completion. Rather than moving files in one step, we recommend copying
(downloading) and then manually deleting from the source.
Things to Check Before Using FTP
About the Storage Folder
• lData between the AB cursors will be saved when the time axis/trace cursor is
displayed.
• lData for the channel which is ON will be saved.
• lWaveform for the block which is displayed during memory division will be displayed.
• lThinning setting will not be considered during text saving. All data is saved at
all times.
