6.3.1 MMEMory Commands
The MMEMory system provides mass storage capabilities for the R&S CMW 500.
File and directory names
The <file_name> and <directory_name> parameters are strings. Some commands use
a fixed directory; for others the <file_name> can contain the complete path including
the drive name and all subdirectories, e.g. 'C:\TEMP\TRASH\test.txt' for the file named
test.txt in the TEMP\TRASH subdirectory of the internal hard disk drive C:\. If no
complete path is specified, the file location is relative to the current directory (queried
with MMEMory:CDIRectory?). The file name itself may contain the period as a
separator for extensions.
File and directory names can be chosen according to Windows™ conventions; the
restrictions placed on file names known from DOS systems do not apply. All letters and
numbers are allowed, as well as the special characters "_", "^", "$", "~", "!", "#", "%",
"&", "-", "{", "}", "(", ")", "@" and "`". Reserved file names are CON, AUX, COM1, ...,
COM4, LPT1, ..., LPT3, NUL and PRN.
The use of wildcards ? and * is not allowed.
MMEMory:CATalog? [<directory_name>]
Returns the contents of the current or of a specified directory.
'<directory_name>' String parameter to specify the directory. If the directory is
omitted, the command queries the contents of the current
directory, to be queried with MMEMory:CDIRectory?
