Figure 11-4. This illustrates the USB signal analyzer file naming convention.
When a USB store of the signal analyzer data is requested, and if the signal analyzer
directory does not exist or contains no files with the appropriate naming conventions, the
drive will write the analyzer data to a file or files with the storage sequence number of
zero (00). If the directory already includes signal analyzer data files with the appropriate
naming conventions, the drive automatically uses a number sequence that is one greater
than the highest storage sequence number listed in the directory.
The drive will indicate an ANALYZR STORE error if the largest sequence number is 99.
EXAMPLE
A drive has a drive ID of 22 on which 4 prior stores of analyzer data have been
performed. Channels 1, 2, and 5 of the signal analyzer have completed storage of data.
This will result in the following files being created:
DRIVE022_04_CH1.ALZ
DRIVE022_04_CH2.ALZ
DRIVE022_04_CH5.ALZ
NOTES
The time stamp of the files will always be 1/1/2001 12:00 PM.
The maximum number of files that are allowed in the SIGNAL subdirectory is 100 files.
The operation will fail with an analyzer store error if a signal analyzer store operation
would result in more than 100 files in the directory. The results of the storage operation
that attempts to store in excess of 100 files in the directory are unpredictable and if any
files are created by the signal analyzer store operation in excess of the 100, the contents
of those files are likely to be invalid.
