You can use the internal disk drive or connect an external disk drive for storage of instrument
states, calibration data, measurement data, and plot files. (Refer to Chapter 4, "Printing,
Plotting, and Saving Measurement Results", for more information on saving measurement data
and plot llles.)
The analyzer displays one file name per stored instrument state when you list the disk
directory. In reality, several llles are actually stored to the disk when you store the instrument
state. Thus, when the disk directory is accessed from a remote system controller, the directory
will show several flies associated with a particular saved state. The maximum number of files
that you can store on a disk depends on the directory size. You can delbre the directory size
when you format a disk. See Table 12-3 for the default directory size for floppy disks and hard
disks.
The maximum number of instrument states and calibrations that can reside on a disk is limited
Bytes free : is the available disk space. If your disk is formatted in IJF', this value is the
largest contiguous block of disk space. Since the analyzer is reporting the largest contiguous
block of disk space, you may or may not see the bytes free number change when you delete
disk space. That number is updated whenever you save to or delete files from the disk.
A disk file created by the analyzer appends a sufllx to the file name. (This is on the analyzer's
directory and is not visible.) The suffix consists of one or two characters: the ilrst character is
the file type and the second is a data index. (Refer to 'Iable 12-2 for the deilnitions of each
