Configuration File Management – System MMEMory 
The MMEMory system provides mass storage capabilities for the CMU. The functionality of this system 
is included in the Data menu; see CMU200/300 operating manual. 
The mass storage of the CMU may be internal or external. The internal mass storage device is a sec-
tion on the internal hard disk that is reserved for mass storage (directory c:\temp). The external mass 
storage device is either a floppy disk or a PCMCIA memory card, depending on the instrument configu-
ration. The <msus> (mass storage unit specifier) parameter in the MMEMory commands denotes the 
root directory of the INTernal or EXTernal mass storage device.  
The <FileName> parameter is a string. The contents of the string may contain characters for specifying 
subdirectories, e.g. "\TEMP\TRASH\test.txt" for the file named test.txt in the TEMP\TRASH subdirectory 
of the root directory or "TEMP\TRASH\test.txt" for the file named test.txt in the TEMP\TRASH subdirec-
tory of the current directory, to be queried with the base system command MMEMory:DIRectory 
[:CURRent]?. The file name itself may contain the period as a separator for extensions.

Command description 
This command saves the configuration of the current function group and test mode to a configuration file. A "?" in 
the specified file name will be replaced by current numbers that are automatically incremented, starting with zero. 
The auto-increment function overwrites an existing file with a "9" in its file name. For instrument settings that may 
be different in manual and remote control (e.g. the repetition mode for many measurements) the manual setting 
is saved. The command is available in all function groups. This command is CMU-specific.
