7.3.6 MMEMory Commands
The MMEMory system provides mass storage capabilities for the R&S CMW500. For
MMEMory commands related to command macros see
chapter 7.3.1, "Macro Com-
mands" , on page 196.
The following rules apply to parameters specifying files or directories:
●
Parameters for specification of file names and directory names are strings.
●
You can specify complete absolute paths including the drive name and all subdirec-
tories. For locations in a network use the Universal Naming Convention (UNC) format
'\\server\share'
.
Examples:
'C:\TEMP\TRASH\test.txt'
specifies the file named
test.txt
in
the directory
TEMP\TRASH
of the internal hard disk drive
C:\
.
'\\myserver\data\archive\test.txt'
specifies the file named
test.txt
in
the subdirectory
archive
of the share
data
on the server
myserver
.
●
If you specify a string containing an absolute path but no drive or server, the default
storage unit is prefixed automatically (see
MMEMory:
​
MSIS
​
on page 217).
●
If you specify a string containing a relative path, the current directory is prefixed
automatically (see
MMEMory:
​
CDIRectory
​
on page 213).
●
Alias strings facilitate the entry of paths. To display the predefined alias strings and
the assigned paths see
MMEMory:
​
ALIases
​
on page 210. The defined strings can
be combined with normal text to specify file paths. Example:
'@SAVE\myfile.dfl'
specifies the file
myfile.dfl
in the save directory,
assigned to the alias
@SAVE
.
●
The use of wildcards ? and * is only allowed if explicitly stated for a command. Wild-
cards are only allowed in the last component of the string.
Example:
'archive\*test*'
allowed,
'archi*\test1.txt'
not allowed
●
A file name itself may contain the period as a separator for extensions.
●
A single period represents the current directory
●
A double period represents the parent of the current directory
●
Example: Assume that the default storage unit equals
'D:'
and the current directory
equals
'\user\data'
. Then the following commands yield the same result:
MMEM:CAT?
MMEM:CAT? '*'
MMEM:CAT? '*.*'
MMEM:CAT? '.\*.*'
MMEM:CAT? '..\data\*.*'
MMEM:CAT? '..\data'
MMEM:CAT? '\user\data\*.*'
MMEM:CAT? 'D:\user\data\*.*'
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
