where waveforms are stored, and \SETUP.ARB, where instrument set-ups are stored.
The instrument will use these directories exclusively for its files. Each directory may
hold up to 510 files, disk capacity permitting. If more than 510 files are stored in these
directories some will be invisible to the instrument because its directory cache buffers are
a finite size.

Formatting

Pressing the memory card... soft-key calls the MEMORY CARD screen:
The screen displays the memory card size, its name and the unused capacity. If either the
WAVES or SETUP directories are full the screen will show free: 0·0MB.
The instrument requires cards formatted with the FAT16 file system (see above). This is
the standard format for new card with capacities from 32 MB to 1 GB but previously
used cards may have been reformatted elsewhere.
To reformat as FAT16 press the format... soft-key followed by ok on the
subsequent screen. The instrument will warn that re-formatting will cause any data on the
card to be lost.

Saving Files to a Memory Card

When creating files the instrument uses the 8.3 file naming format where the 8 is the 8
character filename and 3 is the file extension. The user chooses the filename and the
instrument adds the extension. The instrument does not create Windows long filenames.
If long filenames exist on the memory card they are ignored by the instrument and the 8.3
alias name is used instead and will appear on the LCD screen.

Avoiding Long Filenames

If long filenames are allowed to get into the directories that the instrument uses they
consume directory space and will reduce the maximum number of files that can be seen
by the instrument. Unfortunately it is very easy to inadvertently create long filename
entries when using the card reader/writer; simply saving a waveform as wave.wfm will
create a long filename entry and an alias. This is because Windows takes the filename
literally as it is entered and, as 8.3 filenames do not allow lower case, any lower case
letter in a filename will produce a long filename. To avoid the problem in the above
example it is necessary to save the file as WAVE.WFM.
The Waveform Manager application supplied will ensure that all filenames are short
provided that the download to memory card function is used to transfer waveforms to the
card reader/writer.

Storing and Recalling Set-Ups

Complete set-ups can be stored to or recalled from the memory card using the screens
called by the STORE and RECALL keys. On the single-channel instrument the store
function is only available by means of the store... soft key on the UTILITY menu.
