7.12.1 File Naming Conventions
To enable files in different file systems to be used, the following file naming conventions
should be observed.
The file name can be of any length and no distinction is made between uppercase and
lowercase letters. The file and the optional file extension are separated by a dot. All letters
and numbers are permitted (numbers are, however, not permitted at the beginning of the
file name). Where possible, special characters should not be used. Use of the slashes
"\" and "/" should be avoided since they are used in file paths. A number of names are
reserved by the operating system, e.g. CLOCK$, CON, AUX, COM1...COM4,
LPT1...LPT3, NUL and PRN.
In the R&S Signal Generator all files in which lists and settings are stored are given a
characteristic extension. The extension is separated from the actual file name by a dot
(see the following table containing a list of the file types).
The two characters "*" and "?" function as "wildcards", i.e. they are used for selecting
several files. The "?" character represents exactly one character, while the "*" character
represents all characters up to the end of the file name. "*.*" therefore stands for all the
files in a directory.
When used in conjunction with the commands, the parameter <file_name> is specified
as a string parameter with quotation marks. It can contain either the complete path
including the drive, only the path and file name, or only the file name. The file name must
include the file extension. The same applies for the parameters <directory_name> and
<path>. Depending on how much information is provided, either the values specified in
the parameter or the values specified with the commands MMEM:MSIS (default drive) and
MMEM:CDIR (default directory) are used for the path and drive setting in the commands.
Before the instrument settings can be stored in a file, they have to be stored in an inter-
mediate memory using common command *SAV <number>. The specified number is
subsequently used in the MMEM.STOR:STATe<number>, <file> command. Also,
subsequently to loading a file with instrument settings with command MMEM:LOAD:STAT
<number>, <file>, these settings have to be activated with the common command
*RCL <number>.
Example:
In the example below, the current instrument setting is always stored in the file
'test1.savrcl' in the directory 'user' on the internal hard disk.
*SAV 4
MMEM:STOR:STAT 4,"d:\user\test1.savrcl"
If the complete path including the drive letter is specified, the file is stored in the specified
path.
MMEM:MSIS 'D:'*SAV 4
MMEM:STOR:STAT 4,"\user\test1.savrcl"
If the parameter only contains the path and file name, the default drive set with the
MMEM:MSIS command is effective.
