Filesystem

Bases: SCPICmdRead

The FILESystem command.

Description
  • This query-only command returns the directory listing of the current working directory. This query is the same as the FILESystem:DIR? query.
Usage
  • Using the .query() method will send the FILESystem? query.
  • Using the .verify(value) method will send the FILESystem? query and raise an AssertionError if the returned value does not match value.
SCPI Syntax
- FILESystem?
Properties
  • .copy: The FILESystem:COPy command.
  • .cwd: The FILESystem:CWD command.
  • .delete: The FILESystem:DELEte command.
  • .dir: The FILESystem:DIR command.
  • .mkdir: The FILESystem:MKDir command.
  • .print: The FILESystem:PRInt command.
  • .readfile: The FILESystem:READFile command.
  • .rename: The FILESystem:REName command.
  • .rmdir: The FILESystem:RMDir command.
  • .writefile: The FILESystem:WRITEFile command.

copy property

Return the FILESystem:COPy command.

Description
  • This command (no query form) copies a named file to a new file. The new file might be in a totally separate directory than the old file. You can only copy one file at a time using this command. Wild card characters are not allowed.
Usage
  • Using the .write(value) method will send the FILESystem:COPy value command.
SCPI Syntax
- FILESystem:COPy {<source file path>,<destination file path>}
Info
  • <source file path> is a quoted string that defines the file name and path. If the file path is within the current working directory, you need only specify the file name.
  • <destination file path> is a quoted string that defines the file name and path. If the file path is within the current working directory, you need only specify the file name.

cwd property

Return the FILESystem:CWD command.

Description
  • This command specifies the current working directory (CWD) for FILESystem commands. The default working directory is ‘E:/’. Anytime you use this command to change the directory, the directory that you specify is retained as the current working directory until you either change the directory or you delete the directory. If you delete the current working directory, the oscilloscope resets current working directory to the default directory the next time the oscilloscope is powered on or the next time you execute a file system command. This command supports the permutations of file and directory names supported by Microsoft Windows: Relative path names; for example, ‘./Temp’ Absolute path names; for example, ‘E:/MyWaveform’ Implied relative path names; for example ‘newfile.txt’ becomes ‘E:/TekScope/newfile.txt’ if the current working directory is ‘E:/TekScope’
Usage
  • Using the .write(value) method will send the FILESystem:CWD value command.
SCPI Syntax
- FILESystem:CWD {<new working directory path>}
Info
  • <new working directory path> is a quoted string that defines the current working; a directory name can be up to 128 characters.

delete property

Return the FILESystem:DELEte command.

Description
  • This command deletes a named file. If you specify a directory name, it will delete the directory and all of its contents, the same as the RMDir command. You can also specify the filename as *.* to delete all of the files in the current or specified directory.
Usage
  • Using the .write(value) method will send the FILESystem:DELEte value command.
SCPI Syntax
- FILESystem:DELEte <file path>
Info
  • <file path> is a quoted string that defines the file name and path. If the file path is within the current working directory, you need only specify the file name.
  • *.* will delete all files and subdirectories within the current working directory.

dir property

Return the FILESystem:DIR command.

Description
  • This query-only command returns a comma separated list of quoted strings. Each string contains the name of a file or directory in the folder referred to by the FILESYSTEM:CWD command.
Usage
  • Using the .query() method will send the FILESystem:DIR? query.
  • Using the .verify(value) method will send the FILESystem:DIR? query and raise an AssertionError if the returned value does not match value.
SCPI Syntax

print property

Return the FILESystem:PRInt command.

Description
  • This command (no query form) prints a named file to a named port. This command is the same as the FILESYSTEM:READFILE command. This command is not IEEE 488.2 compliant for the following reasons: The command produces output on the 488.2 bus. Queries, not commands, are the only message units that should produce output on the 488.2 bus. Errors might not be recognized if they occur while data is being output in response to this command. This will be evident if a command is sent to the instrument before all of the data generated by this command is read. In such cases, you should send a device clear message to the instrument. The command does not use a standard 488.2 output format. The closest defined format is the indefinite format of ARBITRARY BLOCK PROGRAM DATA encoding. However, this command output omits the initial ‘#0’ characters needed for that format. Newlines, ASCII value 10, can be included in the output data. Output on the bus can be terminated by newlines. The output of this command is only terminated by .
Usage
  • Using the .write(value) method will send the FILESystem:PRInt value command.
SCPI Syntax
- FILESystem:PRInt <filepath>, GPIb
Info
  • <file path> is a quoted string that defines the file name and path. If the file path is within the current working directory, you need only specify the file name.
  • GPIb specifies that the hard copy is sent out of the GPIB port. GPIb is the only port allowed for this command.
