FTP operating environment and notes
A FTP probe acquires a measurement file from the measurement-target FTP server, or transfers a prepared measurement file to the measurement-target server and measures the time required for file transfer. The measurement file must already be stored in the following folder:
-
Transfer to the FTP server
installation-folder\agtv\probedata\ftp
-
Transfer from the FTP server
Under the user's home directory specified in the measurement condition
The following describes and provides notes on a FTP operating environment.
Handling of the transferred file
Handling of the transferred file depends on the transfer direction, as described below:
- UPLOAD
-
If the file to be transferred has the same name as a file in the home directory of a user at the target FTP server, the file is overwritten. Therefore, the total size of the data in the target measurement file does not keep increasing.
- DOWNLOAD
-
Data in the acquired file is discarded each time measurement is completed.
Data type during transfer
The FTP probe supports only the ASCII data type during transfer.
RFC compliance

RFC959: File Transfer Protocol (FTP)
For the functions that are not compliance with RFCs and the restrictions, see the above notes.
