R&S FSP Remote Control – Description of Commands
MMEMory Subsystem
6.14 MMEMory Subsystem
The MMEMory (mass memory) subsystem provides commands which allow for access to the storage
media of the instrument and for storing and loading various instrument settings.
The various drives can be addressed via the "mass storage unit specifier" <msus> using the conven-
tional DOS syntax. The internal hard disk is addressed by "D:", the floppy disk drive by "A:" and a mem-
ory stick by “F:”..
The file names <file_name> are indicated as string parameters with the commands being enclosed in
quotation marks. They also comply with DOS conventions.
DOS file names consist of max. 8 ASCII characters and an extension of up to three characters separated
from the file name by a dot "." Both, the dot and the extension are optional. The dot is not part of the file
name. DOS file names do not distinguish between uppercase and lowercase notation. All letters and dig-
its are permitted as well as the special characters "_", "^", "$", "~", "!", "#", "%", "&", "-", "{", "}", "(", ")", "@"
and "`". Reserved file names are CLOCK$, CON, AUX, COM1 to COM4, LPT1 to LPT3, NUL and PRN.
The two characters "*" and "?" have the function of so-called "wildcards", i.e., they are variables for
selection of several files. The question mark "?" replaces exactly one character, the asterisk means any
of the remaining characters in the file name. "*.*" thus means all files in a directory.
MMEMory:CATalog:LONG? <path>
This command queries the directories and files in the given path.
Parameter: <path>::= DOS path
Example:
"MMEM:CAT:LONG? 'D:\USER\DATA'"
'queries the contents of directory D:\USER\DATA
Return value: <used_bytes_in_this_directory>,<free_bytes_on_this_disk>,
"<file_name>,<file_type>,<filesize_in_bytes>",
"<file_name>,<file_type>,<filesize_in_bytes>", …
with
<file_name>: name of file or directory
<file_type>: DIR (directory), ASCii (ASCII file), BINary (binary file) and STATe (file
with device settings)
<filesize_in_bytes>: size of file, 0 for directories
Characteristics: *RST value: -
SCPI: conform
Mode: A
For reasons of compatibility with the FSE instruments, addressing the hard disk by
"C:" is also accepted. Since hard disk "C:" is reserved for instrument software, all
read and write operations are rerouted to hard disk "D:" in normal operation (ser-
vice level 0).
