Auto-Store Waveform
File Naming
The default notation for waveform files is Stt.nnn for manually
stored files and Att.nnn for automatically stored files, the characters
S and A representing the two storage methods, respectively.
When automatically generating a file name, the system uses the
assigned name plus a three-digit sequence number. If the assigned
waveform name is already in the default ‘Stt’ form — such as SC1,
STB — the name will be modified to the ‘Att’ form: AC1, ATB and
so on. All other user-assigned names remain as entered.
More on Auto-Stored FilesIf “Fill” is selected and default names are used, the first waveform
stored will be Axx.001, the second Axx.002, and so on, continuing
until the storage medium is filled, the file number reaches 999, or
there are more than 2400 files in the current working directory.
If “Wrap” is selected, the oldest auto-stored waveform files will be
deleted whenever the medium becomes full. And the remaining
auto-stored waveform files will be renamed — the oldest group of
files will be named “Axx.001”, the second oldest “Axx.002” and so
on.
The current sequence number is deduced from inspection of all file
names in the working directory, regardless of file type — panel, hard
copy or waveform. The highest occupied numeric file-name
extension of the form ‘nnn’ is determined, and the next highest
number is used as the current generation number for storage
operations.
Deleting Files When a file generation is deleted, all files designated with the three-
digit sequence number of the file-name extension will be deleted,
regardless of file type.
Media Size/Storage
Availability
The mass-storage file system indicates media size and storage
availability in kbytes where 1 kbyte = 1024 bytes. Many media
manufacturers specify the available storage in Mbytes where
1 Mbyte = 1 million bytes. This results in an apparent mismatch in
specified versus actual media storage availability, when in fact the
availability in bytes is identical.
