System Command Reference Section

User Pattern Disk Operations

This subsystem is used for controlling the floppy disk used as mass memory with the

instrument. It is recommended that a floppy disk is reserved for sole use by the

Agilent 70843.

MMEMory:INITialize

The INITialize command is used to initialize the floppy disk mass storage medium.

This command is an event and has no *RST condition.

MMEMory:DELete <file name>

The DELete command removes a file from the floppy disk. The <file name> parameter

specifies the file name to be removed. It is a string parameter. File names are

‘HPPATxx.DAT’, where xx ranges from 05 through 12. For example to delete disk

pattern 7. the command would be “MMEM:DEL ‘HPPAT 07.DAT’”.

This command is an event and has no *RST condition or query form.

MMEMory:CATalog? <NR3>,<NR3> { ,<file entry> }

The CATalog? command is query-only and returns information on the current contents

and state of the floppy disk. Upon a CATalog? query, the instrument reads the floppy disk

and returns its directory information. The information returned is composed of two

numeric parameters followed by as many strings as there are files in the directory list. 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:

The <file size> is returned in bytes. The number of <file entry> items that is returned is

limited to eight.

MMEMory:MPResent? <boolean>

This command is short for Media Present. It returns a boolean indicating whether a floppy

disk is present.
