Disk Disk stores the summary information to a disk. The store
summary menu allows you to specify the first four characters of the file
name. The last four characters are reserved for consecutively numbering
any subsequent summary files stored to the disk. If you select SUMM as
the first four characters of the file name, the file name of the summary
file stored to the disk is MSUM0000.SUM. The file name of the second
summary file stored to the disk is MSUM0001.SUM. Each subsequent
time the oscilloscope stores a summary file to the disk, it checks which
files are already on the disk, then increments the last four digits of the
file name by one. If you change disks, the file number starts over again at
MSUM0000.SUM
Theoretically you can have up to 9,999 summary files. However, there are
two limits that keep you from obtaining that many files. The first limit is with
MS-DOS itself. MS-DOS limits the root directory to 224 entries (an entry is
either a file name or subdirectory). Because the oscilloscope can only access
files in the root directory, that limits the maximum number of files the
oscilloscope can store to a disk to 224.
The second limit is the potential size of a summary file. The size of the
summary file depends on how many tests are made and the setup of the Run
until softkey.
Usually you will not have 224 summary files. However, if you are also storing
screen and waveform information to the disk, there is the potential to fill up
the disk. If the oscilloscope cannot store additional files to the disk, the
header portion of the summary is still updated, but additional logs are not
appended to the summary file.
Messages like "Channel 1 could NOT be saved to the disk" are caused by the
following conditions:
•
The disk is write-protected.
•
An MS-DOS disk is not in the drive.
•
The disk is full.
•
The maximum number of 224 files are already stored on the disk.
