Keysight 53220A/53230A User’s Guide 275
In addition to the list of files, the commands also provide the total amount of
memory used and the total amount of memory available (free) on the specified
drive.
MMEMory:CATalog[:ALL]? [<“folder”>]
MMEMory:CATalog:DATA? [<“folder”>]
MMEMory:CATalog:STATe? [<“folder”>]
The folder parameter format is drive:path. drive is either INT (internal flash
memory) or USB (external memory device). path is an absolute path and folder
name beginning with \. If a folder is not specified, the contents of the specified
current folder (MMEMory:CDIRectory) or the contents of the drive’s root directory
are returned.
The format of the data returned is:
<total memory used>, <total memory free>, <“file listing”>
“file listing” with quotes (““) included is further separated into:
“<file name>, <file type>, <file size>”
Memory used, memory free, and file size are given in bytes. Examples of what the
individual CATalog commands might return for a folder on an external USB
memory device containing a sub-folder plus a .csv data file, a .dat data file, and a
state file are given as follows:
MMEMory:CATalog[:ALL]?
