should be avoided since they are used in file paths. A number of names are reserved
for the operating system, e.g. CLOCK$, CON, AUX, COM1...COM4, LPT1...LPT3, NUL
and PRN.
In the R&S SMBV all files in which lists and settings are stored are given a characteris-
tic extension. The extension is separated from the actual file name by a dot (see Chap-
ter 4.7.2.1, "Extensions for User Files", on page 109 for an overview of the file types).
The two characters "*" and "?" function as "wildcards", meaning 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 files in a directory.
When used in conjunction with the commands, the parameter <file_name> is speci-
fied as a string parameter with quotation marks. It can contain either the complete path
including the drive, only the path and the 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 command MMEM:CDIR (default directory)
are used for the path and the drive settings 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 :MMEMory:STORe:STATe on page 575 command. Also,
subsequently to loading a file with instrument settings with command :MMEMory:
LOAD:STATe on page 573, these settings have to be activated with the common
command *RCL <number>.
