Save
what date and time it was last modified. In addition, you can use the Edit Register Names key to enter
custom names for each register.
In products that run multiple instances of the X-Series Application, save with different register name if you
do not want to overwrite the register of another running instance.
Although these 16 registers are the only registers available from the front panel, there are 128 state
registers available in the instrument. Registers 17–128 are only available from the SCPI interface, using
the *SAV command.
There is one set of 128 state registers in the instrument, not one set for each Mode. When a state is saved,
the Mode it was saved from is saved with it; then when it is recalled, the instrument switches to that Mode.
After the save completes, the corresponding register menu key annotation is updated with the date and
time and the message "Register <register number> saved" is displayed.

Mass Storage Catalog (Remote Command Only)
Key path
SCPI Only
Remote Command :MMEMory:CATalog? [<directory_name>]
Notes The string must be a valid logical path.
Queries disk usage information (drive capacity, free space available) and obtains a list of files and
directories in a specified directory in the following format:
<numeric_value>,<numeric_value>,{<file_entry>}
It returns two numeric parameters and as many strings as there are files and directories. The first
parameter indicates the total amount of storage currently used in bytes. The second parameter
indicates the total amount of storage available, also in bytes. The <file_entry> is a string. Each <file_
entry> indicates the name, type, and size of one file in the directory list:
<file_name>,<file_type>,<file_size>
As the windows file system has an extension that indicates file type, <file_type> is always empty.
<file_size> provides the size of the file in bytes. For directories, <file_entry> is surrounded by square
brackets and both <file_type> and <file_size> are empty
